Game Systems | Star Savior DB

Attributes

Every savior has one of five attributes. Advantage gives bonuses to damage and debuff accuracy; disadvantage penalizes both.

Element Wheel

The three basic elements form a cycle:

Sun →

Star →

Moon →

Sun

Order and Chaos are strong against each other:

Order ↔

Chaos

Advantage effects:

+5% base damage increase (hardcoded, stacks with stat bonuses)
+30% Effect Hit bonus (debuff accuracy)
Per-attribute damage bonus stat applies (e.g. DamageUp vs Sun)
Target's Attribute Guaranteed Effect RES applies
+1 base Toughness damage

Disadvantage effects:

-5% base damage decrease (hardcoded)
-30% Effect Hit penalty (debuff accuracy)
0 base Toughness damage (can't break without bonus)

Debuff Accuracy

When a skill applies a debuff, two sequential checks determine whether it lands: the Activation Rate roll and the Effect Hit check.

Quick Guide

Landing a debuff is two coin flips back to back. Both must succeed.

Flip 1 — Does the skill even try?

Check the skill's activation chance (shown on the tooltip). A skill that says "75% chance to stun" simply rolls 75% here. If it fails, nothing happens — Effect Hit doesn't matter.

Flip 2 — Does the target resist?

Your Effect Hit minus their Effect RES = your chance to land. Element advantage adds 30%; disadvantage subtracts 30%.

Everyone starts with 100% Effect Hit and 0% Effect RES, so against a base target you have 100% to land. But the built-in 20% Guaranteed Effect RES caps your maximum at 80% — unless you have Guaranteed Effect Hit to push past it.

Worked Example

Your caster has 120% Effect Hit. The target has 45% Effect RES. You have element advantage. The skill has a 100% activation chance.

Flip 1: 100% activation — auto-pass
Flip 2: 120% - 45% + 30% = 105%
But the target has 20% Guaranteed Effect RES, capping you at 80%
Final chance to land: 80%

Another Example

Same caster (120% Effect Hit), but now you're at element disadvantage against a target with 60% Effect RES. Skill activation is 75%.

Flip 1: 75% activation — must pass first
Flip 2: 120% - 60% - 30% = 30%
30% is under the 80% cap, so no cap applies
Overall chance: 75% × 30% = 22.5%

Detailed Formula

1 Activation Rate

Each skill effect has a base activation chance (ActiveRate), shown on skill tooltips. This is rolled first.

// Roll a random number in [0, 10000)
success = random < ActiveRate
// where 10000 = 100%

A skill with 75% activation chance has ActiveRate = 7500.

2 Effect Hit Check

If the activation roll passes, the game checks whether the target resists using the caster's Effect Hit against the target's Effect RES.

Attribute Advantage

// Check element matchup between caster and target
attributeBonus = 0
if caster has attribute advantage: attributeBonus = +3000 (+30%)
if caster has attribute disadvantage: attributeBonus = -3000 (-30%)

Base Effect Rate

baseRate = caster.EffectHit - target.EffectRES + attributeBonus

Default EffectHit = 10000 (100%), default EffectRES = 0.

Guaranteed Effect Hit / RES

A separate "guaranteed" layer can override the base rate. If the target has attribute advantage over the caster, their Attribute Guaranteed Effect RES also applies.

// Attribute-conditional guaranteed resistance
attrGuaranteedRES = 0
if target has attribute advantage over caster:
attrGuaranteedRES = target.AttributeGuaranteedEffectRES

// Net guaranteed value
guaranteedNet = caster.GuaranteedEffectHit
- (target.GuaranteedEffectRES + attrGuaranteedRES)

Guaranteed Override Logic

The guaranteed value acts as a floor or ceiling that can modify the final rate.

if (baseRate > 0 AND guaranteedNet > baseRate)
OR (baseRate < 0 AND guaranteedNet > 0):
finalRate = guaranteedNet // guaranteed raises the rate

else if baseRate > 0 AND guaranteedNet < 0:
cap = 10000 - |guaranteedNet| // guaranteed caps maximum
if baseRate > cap:
finalRate = cap
else:
finalRate = baseRate

else:
finalRate = baseRate

Final Roll

success = random(0, 10000) < finalRate

Default Stat Values

Stat	Base Value
Effect Hit	100.0%
Effect RES	0.0%
Guaranteed Effect Hit	0.0%
Guaranteed Effect RES	20.0%
Attribute Guaranteed Effect RES	0.0%

The 20% base Guaranteed Effect RES means even with massive Effect Hit advantage, the target always has a minimum ~20% chance to resist (via the cap mechanic), unless the attacker has Guaranteed Effect Hit to counteract it.

Critical Hits

Critical hit chance follows the same subtraction pattern as Effect Hit. Crit damage is then applied as a multiplier.

Crit Rate

Works the same way as Effect Hit — it's the attacker's crit chance minus the defender's crit evasion, then a dice roll.

// Some buffs grant forced crit — bypasses this check entirely
critRate = attacker.CRITRate - defender.CRITEvade
isCrit = random(0, 10000) < critRate

Crit Rate is capped at 100% (10000). CRIT Evade is not a common stat but some buffs/passives grant it.

Crit Damage

When a hit crits, the damage is multiplied by 1 + critDmgBonus. The bonus can be reduced by the defender's CRIT Damage Reduce stat.

critDmgBonus = attacker.CRITDamage - defender.CRITDamageReduce
critDamage = baseDamage * (1 + critDmgBonus)

CRIT Damage is capped at 300% (30000).

Example

Your attacker has 65% CRIT Rate and 180% CRIT Damage. The defender has 0% CRIT Evade and 20% CRIT Damage Reduce. A non-crit hit would deal 5,000 damage.

Crit chance: 65% - 0% = 65%
If it crits: bonus = 180% - 20% = 160%
Crit damage: 5,000 × (1 + 1.6) = 5,000 × 2.6 = 13,000

On average across many hits: 5,000 × (0.35 + 0.65 × 2.6) = 10,200 expected damage per hit.

Damage

Damage calculation uses ATK, DEF, skill scaling, and several multiplicative layers.

Constants

Constant	Value	What It Does
Damage Scale	18500	Global multiplier applied to all base damage after stat scaling. Effectively a normalization constant that the game uses to keep damage numbers in a desired range.
Defence Constant	3000 (PvE) 300 (PvP)	Used in the DEF formula: `DEF/(DEF+Const)`.
Damage Reduce Cap	50%	Total Damage Reduce from all sources (buffs, role bonuses, etc.) cannot exceed 50%. Prevents full damage immunity stacking.
CRIT Rate Cap	100%	CRIT Rate cannot exceed 100%.
CRIT Damage Cap	300%	CRIT Damage bonus cannot exceed 300% (for a max 4x multiplier on crit hits).

Damage Pipeline

Damage is calculated through several multiplicative stages:

Base Damage — Each skill has a scaling factor (e.g., a normal attack might scale at 65% ATK, a hyper skill at 265% ATK). Some skills also scale off DEF or HP. For AoE skills, all scaling factors except SPD are divided by a fixed value of 4 (see AoE Damage Split below)
Defence Reduction — DEF mitigates damage using the defence constant (higher constant = DEF matters less)
Damage Share — Some units can redirect a portion of incoming damage to themselves
Damage Up / Reduce — Additive bonuses from buffs, including role-specific and attribute-specific modifiers (see below). Capped at 50% total reduction
Break Bonus — While target's super armor is broken, attacker gets additional DamageUp (Break)
Critical — If crit: multiply by 1 + (CRITDmg - CRITDmgReduce)
Life Steal — Attacker heals for damage * DamageVampirism%, modified by target's Heal Receive stat

Damage Up/Reduce Breakdown

The Damage Up/Reduce stage combines several sources additively:

totalDmgUp = general DamageUp
+ DamageUp vs [Role] // e.g. DamageUp vs Striker
+ DamageUp vs [Attribute] // e.g. DamageUp vs Sun
+ DamageUp vs [Attack Type] // e.g. DamageUp vs Slash
+ DamageUp (Break) // only if target is broken

totalDmgReduce = general DamageReduce
+ DamageReduce vs [Role]
+ DamageReduce vs [Attack Type] // e.g. DamageReduce vs Element
+ DamageReduce (Break) // while self is broken
+ NonCrit DamageReduce // only on non-crit hits

modifier = totalDmgUp - totalDmgReduce

Attack type modifiers (Slash, Impact, Element, Spirit) let units specialize in resisting or dealing extra damage against specific damage types. NonCrit Damage Reduce only applies when the hit doesn't crit, rewarding high CRIT Rate builds.

Base Damage Formula

Each skill has scaling factors (ATK%, HP%, DEF%, SPD%) that are combined with the attacker's stats to produce the raw base damage before any multipliers.

// Scaling factors are divided by targetCount (see AoE below)
atkScaling = (AtkFactor + skillLevelBonus) / targetCount
hpScaling = HpFactor / targetCount
defScaling = DefFactor / targetCount
spdScaling = SpdFactor // SPD is NOT divided

baseDamage = (ATK × atkScaling
+ HP × hpScaling
+ DEF × defScaling)
× (1 + SPD_bonus × spdScaling)

baseDamage = baseDamage × DamageScale

The skillLevelBonus is the hidden DMG% gained from leveling the skill (the "DMG +1%", "DMG +2%" etc. shown in skill level descriptions). It is added directly to the ATK scaling factor before division.

AoE Damage Split

Skills that target all enemies (ENEMY_ALL) have their scaling factors divided by a fixed divisor of 4, regardless of how many enemies are actually on the field. This division is hardcoded in the game's damage calculation and applies to ATK, HP, and DEF scaling factors (but not SPD).

// targetCount is set BEFORE damage calculation
targetCount = 1 // default for single-target
if (skill.targetType == ENEMY_ALL)
targetCount = 4 // always 4, even vs 1 enemy

This means AoE skills always deal 1/4 of their listed scaling per target. The scaling factors shown in skill data represent the total damage budget, not the per-target amount.

Practical Impact

Skill Type	Listed Factor	Per-Target Factor	Example
Standard S1 (single)	65%	65%	Most saviors' basic attack
AoE S1	120%	30%	Luna's Defensive Mana Shot
AoE S3 (hyper)	265%	66.25%	Luna's The World I See
Single-target S3	115%	115%	Lydia's Void Within the Tome

The /4 divisor applies even when only 1 enemy remains. AoE skills do not redistribute unused damage to fewer targets. DOT and fixed-damage effects bypass this divisor.

Defence Formula

The defence constant determines how quickly DEF reduces damage. A higher constant means DEF matters less (you need more to see results).

// Standard defence reduction formula
reduction = DEF / (DEF + DefenceConst)
damage = baseDamage * (1 - reduction)

Damage Up/Reduce: Skill & Target Type Modifiers

In addition to the general Damage Up/Reduce stats, the game applies separate modifiers based on the skill slot and target type. These are additive with other Damage Up/Reduce sources.

// Attacker's skill-type bonus
skillDmgUp = DamageUp vs [Skill Type] // Basic / Special / Hyper

// Attacker's target-type bonus
targetDmgUp = DamageUp vs [Target Type] // Single Target / AoE

// Defender's corresponding reduction
skillDmgReduce = DamageReduce vs [Skill Type]
targetDmgReduce = DamageReduce vs [Target Type]

These stats can come from buffs, equipment set bonuses, or ranking raid effects. For example, the Chain debuff applies -20% DamageReduce vs AoE, making the target take more damage from AoE skills.

BP Scaling (PvE Only)

Each PvE stage has a recommended BP. The ratio between your team's BP and the stage's recommended BP applies a damage multiplier to both sides. Exceeding the recommended BP gives no bonus — this is purely a penalty system for being under. This only affects PvE — PvP battles have no BP scaling.

Your BP / Recommended	Your Damage	Enemy Damage
≥ 90%	100%	100%
85%	90%	110%
80%	80%	120%
75%	70%	130%
70%	60%	140%
60%	40%	160%
50%	20%	180%
< 50%	10%	190%

The scaling is a smooth curve with 500 entries — the table above shows key breakpoints. No penalty kicks in until you drop below 90% of recommended BP. Between 90% and 50%, your damage drops by roughly 2% for every 1% of BP you're missing. Below 50% you floor at 10% damage dealt / 190% damage taken.

Additional Damage Rules

Damage Variance — Some skills apply a ±5% random jitter to final damage. The roll is random(0.95, 1.05) multiplied against the calculated damage. Only skills tagged with the random damage flag use this.
Damage Limit By HP — Certain bosses have a stat that caps the maximum damage they can take per hit as a percentage of their max HP: maxDmg = MaxHP × DamageLimitRate. This prevents one-shots even from extremely buffed attacks.
Minimum Damage — Damage can never be reduced below 1. Even with extreme DEF stacking and damage reduction, a hit that connects will always deal at least 1 damage.
Evasion Damage — When a hit is evaded (see Hit/Evasion), damage is reduced by 50%, debuffs are not applied, and no Toughness damage is dealt.

Example

An attacker with 2,500 ATK uses a skill with 200% scaling against a target with 1,500 DEF. The attacker has 25% Damage Up from buffs, no other modifiers. Non-crit hit in PvE.

Base damage: 2,500 × 2.0 = 5,000
Defence reduction: 1,500 / (1,500 + 3,000) = 33.3%
After DEF: 5,000 × (1 - 0.333) = 3,335
Damage Up: 3,335 × (1 + 0.25) = 4,169

Chain Damage

TL;DR

Chain DMG is a bonus true damage hit that procs when a condition is met (e.g. on crit, on Basic Skill, when attacked). It scales from a stat (usually ATK or Max HP) at a set rate, benefits from Damage Up and Break bonus, but ignores DEF, CRIT, Damage Reduce, and does not proc Life Steal. Think of it as an extra true damage instance tacked onto the triggering action.

Chain Damage (also called Additional Damage) is a separate damage instance triggered after certain actions — basic attacks, critical hits, being attacked, or specific skill conditions. It fires independently of the triggering skill's damage and has its own scaling.

How It Works

Trigger — A skill effect or potential specifies when Chain DMG fires: on attack, on crit, on Basic Skill, after being attacked, etc. Each has a proc chance (e.g. 50% or 100%).
Base Value — The effect specifies a stat to scale from (usually ATK, sometimes Max HP) and a rate. Base Value = Stat × AddDamageRate
Stat Source — The stat can be read from either the caster (self) or the target, depending on the effect.
Damage Modifiers — The base value is then multiplied by the caster's Damage Up buffs (including Break bonus if the target's toughness is broken): Final = (Base + Base × DmgUp%) × DamageScale
Separate Hit — Chain DMG appears as a separate damage number. Multiple Chain DMG effects on the same target from the same action are grouped and applied together.

Formula

// Step 1: Base damage from stat

BaseDmg = Stat(source) × AddDamageRate%

// Step 2: Apply damage multipliers

FinalDmg = BaseDmg × (1 + DamageUp%) × 1.85

// Where DamageUp% is the sum of:

NST_RATE_DAMAGE_UP (general Damage Up buffs)

+ attribute-specific Damage Up (element advantage, etc.)

+ role-specific Damage Up

+ NST_RATE_DAMAGE_UP_BREAK (only if target toughness is broken)

The 1.85 multiplier is the global DamageScale constant (18500 / 10000), the same one used in the normal damage formula. Chain DMG is not affected by DEF, CRIT, Damage Reduce, or Life Steal. Only Damage Up stats on the attacker modify it. True Damage variants (fixed amount) skip stat scaling entirely and deal a flat value.

Common Rates

Chain Damage rates vary by source. Here are typical values found in the game data:

Source	Rate	Stat	Notes
Potentials (Catalyst)	17.5%	ATK	On crit with Basic Skill, hits all enemies, once per turn
Potentials (Double Tap)	5 – 20%	ATK	On Basic Skill vs broken toughness target
Potentials (HP-based)	8%	Max HP	Counter-based: when attacked with no debuffs
Enemy Passives	30 – 50%	ATK	After Basic Skill or on being attacked
Boss Scaling (per stack)	30 – 150%	ATK	Increases per buff stack (e.g. Motif stacks: 30%, 60%, 90%, 120%, 150%)
Boss HP-based	3%	Target Max HP	Scales from target's HP instead of self ATK
Journey Item Effects	5%	Max HP	Charm/item battle effects

Key Differences from Normal Damage

Property	Normal Damage	Chain Damage
DEF Reduction	Yes	No
Can Crit	Yes	No (can be triggered by a crit, but the Chain DMG itself never crits)
Damage Reduce	Yes (buffs, role, etc.)	No
Damage Up	Yes	Yes
Break Bonus	Yes	Yes
Life Steal	Yes (skill damage only)	No

Healing

Heal skills scale off a stat (usually the caster's ATK or the target's Max HP) multiplied by the skill's heal rate, then modified by two stats.

Heal Formula

Each heal skill specifies which stat it scales from (usually the caster's ATK or the target's Max HP) and a heal rate multiplier. Two stats then modify the final amount:

Heal Give — on the caster, increases all healing they provide
Heal Receive — on the target, increases all healing they receive

baseHeal = scalingStat * healRate
modifier = 1.0 + caster.HealGive + target.HealReceive
finalHeal = baseHeal * modifier

Both stats are additive with each other — stacking Heal Give on the healer and Heal Receive on the tank compounds. Life steal from Damage Vampirism also uses this same Heal Receive modifier on the target being healed (the attacker).

Example

A healer with 3,000 ATK and 20% Heal Give uses a skill that heals for 50% of their ATK. The target has 15% Heal Receive.

Base heal: 3,000 × 0.5 = 1,500
Modifier: 1.0 + 0.20 + 0.15 = 1.35
Final heal: 1,500 × 1.35 = 2,025

Super Armor

Bosses (and some saviors) have a Super Armor gauge. When broken, the target takes increased damage and may trigger break-specific effects.

How It Works

Each damaging hit chips away at the Toughness gauge. When it reaches 0, the target enters Break state. Only hits that actually deal damage (Normal or Critical) chip the gauge — misses, nullified hits, and non-damaging skills don't count. The gauge refills after break ends.

Break Effects by Unit Type

Break effects differ depending on the type of unit being broken. The key difference: monsters get their speed gauge reset to 0, but saviors do not.

Effect	Savior	Normal	Elite	Boss
+15% Damage Taken (1 turn)	✓	✓	✓	✓
Speed Gauge Reset to 0	✗	✓	✓	✓
Counter Disabled (1 turn)	✓	✓	✓	✓
Preemptive Guard Disabled (1 turn)	✓	✓	✓	✓

The speed gauge reset is why breaking bosses feels so impactful — it delays their next turn significantly. In PvP, breaking a savior only gives the damage debuff and disables, with no turn delay.

Super Armor Damage Per Hit

Each hit's contribution to breaking the gauge is calculated from attribute matchup and bonus stats:

// Base SA damage depends on attribute matchup
if attacker has attribute advantage:
baseSA = 1
else:
baseSA = 0 // neutral or disadvantage

// Add bonus stats
saDamage = baseSA
+ attacker.SuperArmorDamage
+ attacker.SuperArmorTrueDamage
- defender.SuperArmorDamageReduce

Super Armor True Damage bypasses the defender's reduction stat. If the total is 0 or negative, no gauge damage is dealt that hit.

Example

A boss has Super Armor = 8 and 2 SA Damage Reduce. Your Sun attacker hits a Star boss (advantage). Attacker has 1 Super Armor Damage from gear.

Base: 1 (advantage)
+ SA Damage: 1
- SA Reduce: 2
Per hit: 1 + 1 - 2 = 0 — not enough to chip!

But if the attacker also has 1 Super Armor True Damage (bypasses reduce):

Per hit: 1 + 1 + 1 - 2 = 1 per hit
Needs 8 hits to break the boss

Break Skills

Break Skills are powerful party-wide abilities that activate after breaking enemy Toughness. Each party can equip one Break Skill. When triggered, the skill deals damage (or heals) and deploys a Domain that provides persistent buffs.

How It Works

Break an enemy's Toughness to gain Break Points. Normal enemies grant 1 point, bosses grant 3 points.
Once you accumulate 3 Break Points, the Break Skill becomes available on your next turn.
Activating the skill triggers its damage/heal effect and deploys the Domain.
After use, Break Points reset and the skill enters an 8-turn cooldown.

Break Skills do not trigger counterattacks. The damage scales off all allies' combined stats (total team ATK or HP), not the individual unit's stats.

Break Skills

Break Skill	Type	Scaling	On-Use Effect	Nova
Singularity Observation	AoE DMG	70% Team ATK	—	+4
Star Piercer	AoE DMG	50% Team ATK	+20% Action Gauge (all allies)	0
Cube Overload	AoE Heal	2% Team HP	Omega Protocol: ATK +15%, Effect Hit +15% (2 turns)	0
Dimensional Assault	AoE DMG	50% Team ATK	—	+4
Planetary Purification unreleased	AoE DMG	—	DEF Down on all enemies (1 turn, ignores Effect RES)	—

"Team ATK" means the sum of all allies' ATK stats. Break Skill damage is subject to the AoE /4 divisor like other all-enemy skills. Break Skills can be leveled from 1 to 10, adding up to +10% total damage (or +2% total healing for Cube Overload).

Domain Deployments

When a Break Skill activates, it deploys a Domain that changes the battle environment and provides persistent buffs to your team.

Domain	Break Skill	Effect
Starlight Horizon	Singularity Observation	+20% ATK and +20% DEF to all allies
Strategic Command	Star Piercer	+10% CRIT Rate and CRIT DMG to all; additional +10% to Strikers and Rangers
Cheat Matrix	Cube Overload	+10% SPD to all; additional +10% to Defenders and Supporters
CRF Amplification	Dimensional Assault	+15% ATK and +1 Toughness DMG to all
Witch's Blessing unreleased	Planetary Purification	+10% ATK to all; additional +10% to Casters and Assassins

Enhancement Costs

Break Skills are leveled using Break Skill Support Plans. All break skills share the same cost table (5,150 total plans to max).

Level	DMG Bonus	Cost	Cumulative
1	Base	50	50
2	+1%	50	100
3	+1%	100	200

8	+1%	1,000	2,550
9	+1%	1,200	3,750
10	+2%	1,400	5,150

Cube Overload (healing) follows the same cost table but gains +0.1–0.5% heal per level instead of DMG. Dimensional Assault requires a special unlock item for Lv1 instead of the standard plans.

Constants

Property	Value	Notes
Break Points to activate	3	Same for all break skills
Points per normal break	1	Breaking a non-boss enemy
Points per boss break	3	Instantly charges the break skill
Cooldown after use	8 turns	Must accumulate 3 points again after cooldown

Nova Burst

Nova Burst is a temporary power-up that enhances your savior's attacks with bonus Toughness damage and a unique secondary effect. It's fueled by Nova Force, a shared party resource that accumulates during battle.

How It Works

Gain Nova Force — certain skills have a Nova Force value (shown as a violet badge on skills). Using these skills adds to the party's shared Nova Force gauge.
Fill the gauge to 4 — the gauge holds up to 12 Nova Force, but activation costs 4. Break Skills like Singularity Observation and Dimensional Assault grant +4 Nova Force on use.
Activate with V — press V during a savior's turn to activate Nova Burst, consuming 4 Nova Force.
Enhanced attacks — while active, the savior gains +15% damage dealt plus bonus Toughness Fixed DMG and their unique Nova Burst effect for the duration of that turn.

Nova Force is shared across the entire party. Any savior's skill that has a Nova Force value contributes to the same gauge.

Nova Force Constants

Max Nova Force	12
Activation Cost	4
Nova Force per Skill	+1 (all skills with Nova Force grant +1)
Break Skill Bonus	+4 (Singularity Observation, Dimensional Assault)
Keybind	`V`

Effect Tiers by Skill Type

Each savior has three tiers of Nova Burst effects depending on which skill type is used during activation. Attack and Special skills get the common base effect, while Hyper skills unlock the savior's unique enhanced effect.

Skill Type	Nova Burst Effect
Attack	+1 Toughness Fixed DMG per hit (common)
Special	+1 Toughness Fixed DMG per hit (common)
Hyper	+1 Toughness Fixed DMG + unique savior effect

The "Instant" nova burst effect (Nova Burst Damage Up, +15% damage dealt) is applied at activation regardless of skill type, then removed after the skill ends.

Related Buffs & Debuffs

Buff	Effect
Nova Force Up	Increases Nova Force gauge
Nova Force Down	Decreases Nova Force gauge
Nova Burst Damage Up	+15% damage dealt — applied at Nova Burst activation regardless of skill type (auto-removed after the skill ends)
Toughness Fixed DMG Up	+1 Toughness Fixed DMG per hit (core nova burst buff, bypasses SA Damage Reduce)
Toughness Recovery	Restores own Toughness gauge (used by some support-type nova bursts)

Break Skill Bonus	+4 (Singularity Observation, Dimensional Assault)
Keybind	`V`

Effect Tiers by Skill Type

Each savior has three tiers of Nova Burst effects depending on which skill type is used during activation. Attack and Special skills get the common base effect, while Hyper skills unlock the savior's unique enhanced effect.

Skill Type	Nova Burst Effect
Attack	+1 Toughness Fixed DMG per hit (common)
Special	+1 Toughness Fixed DMG per hit (common)
Hyper	+1 Toughness Fixed DMG + unique savior effect

The "Instant" nova burst effect (Nova Burst Damage Up, +15% damage dealt) is applied at activation regardless of skill type, then removed after the skill ends.

Related Buffs & Debuffs

Buff	Effect
Nova Force Up	Increases Nova Force gauge
Nova Force Down	Decreases Nova Force gauge
Nova Burst Damage Up	+15% damage dealt — applied at Nova Burst activation regardless of skill type (auto-removed after the skill ends)
Toughness Fixed DMG Up	+1 Toughness Fixed DMG per hit (core nova burst buff, bypasses SA Damage Reduce)
Toughness Recovery	Restores own Toughness gauge (used by some support-type nova bursts)

Unique Nova Burst Effects by Savior

When using a Hyper skill during Nova Burst, each savior gains their unique enhanced effect in addition to the base Toughness Fixed DMG bonus. Some saviors also have unique effects on their Attack or Special skill types.

Nova Burst & Toughness Synergy

Nova Burst's core function is accelerating Toughness breaks. The +1 Toughness Fixed DMG from Nova Burst is classified as Super Armor True Damage, which bypasses the enemy's SA Damage Reduce stat.

// During Nova Burst
saDamage = baseSA
+ attacker.SuperArmorDamage
+ attacker.SuperArmorTrueDamage
+ novaBurstBonus // +1 or +2 (True Damage, ignores reduce)
- defender.SuperArmorDamageReduce

The optimal flow is: build Nova Force with skills that have the Nova badge → use a Break Skill (Singularity Observation or Dimensional Assault give +4 Nova Force) → activate Nova Burst on your next turn with a Hyper skill for maximum break damage and unique effect.

Turn Order

Turn order is determined by each unit's Turn Speed stat. Higher speed means the unit acts sooner.

Speed Gauge

Each unit has a speed gauge that fills over time. When it reaches 10000, the unit takes its turn. The rate it fills depends on Turn Speed — higher speed = fills faster = acts sooner.

// Time until a unit's next action
timeToAct = (10000 - currentGauge) / TurnSpeed

// Lower timeToAct = acts first

If a unit's gauge is already at or above 10000, they get an instant turn.

Leader Position

The savior in the Leader slot (first team position) gets +10 Turn Speed in PvE. This is a flat bonus added to their base speed before any other calculations.

Turn 1 Randomization

On the very first turn only, a random multiplier is applied to each unit's Turn Speed to break ties and add variance:

// Only on turn 1
jitter = random(9500, 10500) / 10000 // 0.95x to 1.05x
effectiveSpeed = TurnSpeed * jitter

This is a +/- 5% jitter. After the first turn, speed is used as-is with no randomization — turn order becomes fully deterministic.

Example

Three units start a battle. All gauges begin at 0.

Unit	Speed	T1 Jitter	Effective	Time to Act
A	500	×1.03	515	10000/515 = 19.4
B	500	×0.97	485	10000/485 = 20.6
C	400	×1.01	404	10000/404 = 24.8

Turn order: A → B → C. Units A and B have the same base speed but the jitter broke the tie — A got lucky with a 1.03x roll while B got 0.97x. On subsequent turns, their actual speed (500) is used with no jitter.

Counter

When you prepare a skill of the same kind (Attack, Special, or Hyper) as the enemy's most recently used skill, the COUNTER mark appears on that enemy. Hitting a target in a COUNTER state deals bonus damage.

How It Works

The game tracks the last skill type each enemy used (Attack, Special, or Hyper)
When you select a skill of the same type, the COUNTER mark appears on matching enemies
Attacking a target in the COUNTER state grants +10% Damage Up

Example

An enemy just used their Attack skill. On your turn, you prepare your savior's Attack skill.

The COUNTER mark appears on that enemy
Your attack deals +10% bonus damage against them
If you had used a Special or Hyper skill instead, no COUNTER mark would appear (type mismatch)

Preemptive Guard

Some units have a chance to intercept single-target attacks aimed at their allies, taking the hit in their place. This is checked before the attacker's skill resolves. AoE and multi-target skills bypass Preemptive Guard entirely.

How It Works

When an attacker uses a single-target skill, the game checks if an ally of the target has Preemptive Defend before the attack resolves. If it triggers:

The guarding unit steps in and takes the hit instead of the originally targeted unit
The guarding unit does not attack back — they only absorb the damage
The original attacker's skill still resolves, but against the guarding unit instead

Dead, stunned, or otherwise incapacitated units cannot guard. Preemptive Guard is also disabled for 1 turn when a unit's Toughness is broken.

Guard Rate

guardRate = guard.PreemptiveDefend - attacker.PreemptiveDefendReduce
guardRate = max(0, guardRate)

isGuard = random(1, 10000) <= guardRate

If the attacker has enough Preemptive Defend Reduce, they can completely shut down the guard chance.

Example

A guard has 30% Preemptive Defend. The attacker has 10% Preemptive Defend Reduce.

Guard rate: 30% - 10% = 20%
20% chance the guard intercepts the attack and takes the hit for the targeted ally
The guard does not retaliate — they only absorb the damage

Hit / Evasion

Separate from debuff accuracy, there is a physical hit/evasion system that determines whether an attack connects at full effect. This is governed by HIT and Evasion stats, which are entirely different from Effect Hit and Effect RES.

Hit Check Formula

On each attack, the game rolls to determine if the hit connects normally or is evaded:

hitChance = attacker.HIT - defender.Evasion
isHit = random(0, 10000) ≤ hitChance

Most saviors have 100% HIT (10000) and 0% Evasion by default, so this check almost always passes in normal PvE. It becomes relevant when Evasion buffs are active.

What Happens on Evasion

Damage is reduced by 50%
Debuffs from the skill are not applied
No Toughness damage is dealt

Force Hit / Force Evade

Some buffs grant Force Hit (attacks always connect regardless of evasion) or Force Evade (attacks are always evaded). Force Hit overrides Force Evade when both are present.

Stat Scaling

Final stats are computed using a 3-stage multiplicative pipeline. All percentage stats use a base of 10000 = 100%.

Quick Explanation

A savior's final stats come from stacking several layers on top of their base stats. The key thing to understand is the order — percentage bonuses multiply the pool after flat bonuses are added, so flat bonuses get amplified by percentage bonuses that come later.

In practice: the higher your base stat, the more value you get from percentage bonuses. A 15% ATK buff on a unit with 2,000 ATK gives +300, but on a unit with 3,000 ATK it gives +450.

Stat Calculation Pipeline

Stats are built up in stages. Each stage adds to the running total, and percentage multipliers apply to everything accumulated so far:

// Stage A: Start with base + growth + journey stats
pool = baseStat + growthStat + journeyStat

// Stage B: Add per-level growth, then apply first % multiplier
pool = pool + growthPerLevel
pool = pool + pool * (percentBonus0)

// Stage C: Add flat bonuses (equipment, etc), then apply second % multiplier
pool = pool + flatBonus
pool = pool + pool * (percentBonus1)

// Stage D: Round down
finalStat = floor(pool)

Stat Sources (in order of application)

Flat additions — Equipment main stats, set bonuses, resonance bonuses
Percentage multipliers — Percentage-of-base bonuses (e.g., "ATK +15%") — these multiply the entire pool, so they amplify flat additions too
Rate additions — Flat percentage point additions for rate stats (e.g., "CRIT Rate +5%") — added directly, not multiplied

Example

A savior has 1,000 base ATK and 200 ATK from growth. They equip a weapon with +500 ATK (flat) and a set bonus giving +15% ATK.

Stage A: 1,000 + 200 = 1,200
Stage B (no per-level growth in this example): 1,200
Stage C flat: 1,200 + 500 = 1,700
Stage C percent: 1,700 + 1,700 × 0.15 = 1,700 + 255 = 1,955

Note: the 15% bonus multiplied 1,700 (including the +500 weapon), not just the 1,200 base.

Battle Power Weights

Stat	Weight
ATK	10
HP	55
DEF	5
Turn Speed	5
Overall Scale	12

Full Battle Power Formula

BP is not just a weighted stat sum — it incorporates CRIT, Effect Hit/RES, potential points, limit break, and skill levels as multiplicative layers on top of the base stat score.

// Step 1: ATK factor (accounts for crit scaling)
baseATK = ATK / 10 × 12
atkFactor = baseATK × (1 - critRate) // non-crit portion
+ baseATK × critRate × (1 + critDmg) // crit portion

// Step 2: HP and DEF factors (simple weighted)
hpFactor = HP / 55 × 12
defFactor = DEF / 5 × 12

// Step 3: Speed factor (diminishing returns above 100)
spdFactor = (100 + (SPD - 100) / 5) / 100

// Step 4: Effect Hit/RES factor
hitResFactor = 1 + (effectHit - 1.0 + effectRES) / 10 // minimum 1.0

// Step 5: Combine into first score
// totalPotenPoints = (sum of PP spent on BP-flagged potential levels) × 0.0001
firstScore = (atkFactor + hpFactor + defFactor)
× (1 + totalPotenPoints)
× spdFactor
× hitResFactor

// Step 6: Limit break and skill level multiplier
secondScore = 1 + limitBreak × 0.02 + totalSkillLevel × 0.01

// Final BP
BP = firstScore × secondScore

limitBreak is the unit's limit break count, excluding any levels beyond limit break 3 (capped at 3).
totalSkillLevel is the sum of all four skill levels: Unique Passive + Basic Skill + Special Skill + Ultimate Skill.
totalPotenPoints only counts PP spent on BP-flagged potential nodes — most basic stat potentials do not contribute. Check the potentials page (BP column) to see which ones count.

Per star grade: +2% ATK, +2% HP, +2% DEF
At max (7 stars): +14% ATK, +14% HP, +14% DEF

Party Position Buffs

How Party Slots Work

Standard parties have 4 slots in two rows. The front row has higher targeting priority (80% chance enemies target front) while the back row is safer (20%). Leader is a separate designation for any slot, granting +10 flat SPD.

Journey parties start with 1 savior and expand up to 3 during the run. With 3 slots, the layout is: Slot 0 (back), Slot 1 (front), Slot 2 (back) — so 1 front and 2 back.

Targeting

When an enemy selects a target, the skill's targeting conditions are checked in order. Each condition is an independent dice roll that can narrow the candidate list.

How It Works

A skill can have multiple targeting preferences (e.g. front row + Defender). Each preference is processed sequentially:

The game rolls a dice against the preference's rate (out of 10000). If the roll fails, the preference is skipped entirely — the candidate list is unchanged.
If the roll passes, the candidate list is filtered to only units matching that preference (e.g. front row units only, or Defenders only).
If the filter would result in an empty list (no matching units), the filter is not applied — the candidate list stays as it was.
The next preference then operates on whatever list remains.

After all preferences are processed, a target is randomly selected from the final candidate list.

Common Targeting Patterns

Enemy skills use these row and role preferences:

80% front row — the most common pattern
100% front row — always targets the front row
100% back row — always targets the back row
80% Defender — the most common role preference, often paired with front row
100% Defender — always targets a Defender if one exists

Example

An enemy skill has 80% front row and 80% Defender preference. Your team has a Defender in front, a Striker in front, and a Supporter in back.

Step 1 — Front row roll (80%):
Roll passes → candidate list narrows to the 2 front row units (Defender, Striker)
Step 2 — Defender roll (80%):
Roll passes → candidate list narrows to just the Defender
Final target: Defender

But if the front row roll fails:

Step 1 — Front row roll (80%):
Roll fails → candidate list stays as all 3 units
Step 2 — Defender roll (80%):
Roll passes → candidate list narrows to just the Defender
Final target: Defender (Defender preference still caught it)

Candle Square

Candle Square is the hub for all PvE battle content. Each mode has different rules, restrictions, and reward structures.

Cosmo Gate

Seasonal competitive PvE. Fight powerful bosses for Raid Score and rank against other players for Stellagem and cosmetic rewards.

How It Works

Each season features 2 bosses with 3 escalating difficulty steps each
All saviors fixed at full stats — Star Link stats beyond Lv200 do NOT apply
Saviors and gear used against one boss are locked and cannot be reused on the other boss unless you pay Gold to reset (which also resets your score)
Each step has a 50-turn limit
Step 3 unlocks Challenge of the Stars — optional difficulty modifiers for extra score

Scoring

stepScore = basePoints // fixed per step
+ damagePoints // scaled by boss damage dealt
+ remainingTurns × turnBonus
+ survivingSaviors × saviorBonus

raidScore = stepScore × (1 + difficultyBonus%) // Step 3 only

Component	Step 1	Step 2	Step 3
Base Points	0	158,000	553,000
Max Damage Points	100,000	250,000	2,500,000
Per Remaining Turn	1,000	2,500	2,500
Per Surviving Savior	2,000	5,000	50,000
Battle Power	33,450	48,950	64,450

Total score = sum of all 3 steps per boss, summed across both bosses. Your highest score per boss is saved across attempts.

Boss Roster

Ranking Rewards

Final ranking at season end determines ranking rewards. Top 30% and above receive a seasonal cosmetic item (profile frame), with higher-tier versions for higher ranks.

Rank Tier	Seasonal Cosmetic
Rank 1–3	Tier 3
Top 10 – Top 3%	Tier 3
Top 5% – Top 10%	Tier 2
Top 15% – Top 30%	Tier 1

PvP Contents

Star Savior has two PvP modes: Async Arena (attack AI-controlled defense teams) and Ranked Arena (real-time matches with a draft phase). Both share a tier ladder and seasonal structure.

Game Modes

Async Arena

Draft mode from Gold tier onwards
20 sec turn timer (+5 sec delay)
Fixed level 200, resonance 10
Season rewards based on peak tier
Weekly score decay at Diamond+
Requires minimum 16 saviors for private matches

Stat Scaling

PvP modes apply a stat squish to HP, ATK, and DEF only. Each stat source is then scaled independently using the multipliers below (values are basis points, ÷ 10000).

Mode	Base Stats	Tactics	Star Link	Stellar Archive	Equipment
Strategy Battle	10%	5%	5%	10%	10%
Ranked Match	10%	0%	0%	10%	10%

These multipliers only impact HP, ATK, and DEF — all other stats pass through unscaled. The PvP Defence Constant is 300 (vs 3000 in PvE), compensating for the stat squish so damage mitigation stays proportionally equivalent.

Async Arena Tiers

Score changes per battle are: base amount + tier bonus. The base amount is determined server-side. The bonuses below make climbing easier at lower tiers and taper off at higher ranks. Bronze and Silver have demotion protection (can't drop below tier floor).

Tier	Score	Win Bonus	Loss Bonus	Def Win Bonus	Def Loss Bonus	Weekly Reset To

Bonuses are added to a server-determined base score change. At Bronze/Silver, the large loss bonuses offset the base loss (demotion protection). At Gold, bonuses are equal for wins and losses. From Master onwards, no loss bonus — you take the full base penalty. Weekly Reset To = your score is floored to that tier's minimum each week (e.g. Gold 3 resets to Gold 3's minimum). - = no bonus (base only). Master+ hides opponent info.

Ranked Arena Tiers

Same bonus system as Async. From Gold onwards, Draft mode is enabled. Only attack bonuses apply (no async defense). Score decay at Diamond+ reduces your score weekly if inactive.

Same bonus system as Async — bonuses are added to a base score change. At Bronze/Silver, large loss bonuses offset the base loss (protection). From Gold onwards, no win bonus — only the loss bonus reduces the penalty, and it shrinks each tier. - = no bonus (base only). Master+ hides opponent info.

Win Streak Bonus

Consecutive wins grant bonus score (and in Async, bonus currency) on top of the normal win amount.

Async Arena

Grants both bonus score and bonus currency

6+ wins: +1 score, +1 currency
11+ wins: +2 score, +2 currency

Ranked Arena

Grants bonus score only

4+ wins: +1 score
7+ wins: +2 score
10+ wins: +3 score

Async AI Difficulty

You can choose the difficulty of AI opponents. Higher difficulty grants bonus reward currency per win.

Difficulty	Win Reward Bonus
Beginner	-
Expert	+2
Veteran	+4

Opponent Refresh Cost

Refreshing your async arena opponent list costs gold, escalating with each refresh.

Refresh #	Gold Cost
1st	1,000
2nd	2,000
3rd	4,000
4th	6,000
5th	8,000
6th	10,000
7th	15,000
8th	20,000
9th	50,000
10th	100,000

Sudden Death

PvP battles have a sudden death mechanic that prevents matches from going on indefinitely. The two modes handle this differently.

Async: Elves' Bolt Strike

Deals flat true damage to the attacker's team. Fires once per level, escalating rapidly.

Level	Turn	True Damage
1	13	1,000
2	24	1,500
3	33	2,000
4	40	2,500
5	46	3,000
6	51	6,000
7	55	12,000
8	58	24,000
9	61	48,000

Ranked: Roche Limit

Progressive stat shifts applied to both teams. Each level replaces the previous. Level 1 is the start marker with no effects.

Level	Turn	Damage Up	Effect Hit	HP	DEF	Heal
1	13	-	-	-	-	-
2	22	+10%	+10%	-10%	-10%	-10%

Sudden Death Mechanics

PvP matches have built-in overtime mechanics that escalate damage as the match drags on, preventing stalemates.

Async Arena: Elves' Bolt Strike

At specific turn thresholds, all units take escalating true damage at the end of each turn:

Activates At	True DMG / Turn
Turn 13	100
Turn 24	150
Turn 33	200
Turn 40	250
Turn 46	300
Turn 51	600
Turn 55	1,200
Turn 58	2,400
Turn 61	4,800

Ranked Arena: Roche Limit

Instead of flat damage, Roche Limit progressively buffs offense while crippling defense for both sides:

Phase	DMG Up	Eff Hit	HP%	DEF%	Heal
Turn 13	—	—	—	—	—
Turn 22	+10%	+10%	-10%	-10%	-10%
Turn 30	+20%	+25%	-20%	-20%	-20%
Turn 37	+40%	+50%	-40%	-30%	-40%
Turn 43	+80%	+75%	-60%	-40%	-60%
Final	+160%	+100%	-80%	-50%	-80%

Roche Limit makes defensive stalling increasingly futile — by the final phase, units take massive extra damage with shredded HP/DEF while healing is nearly useless.

Guild

Guilds are the cooperative social system in Star Savior. Members contribute through attendance, donations, and Guild Defense battles. Guilds level up to increase capacity and unlock shop items.

Guild Levels

Guilds gain EXP from member donations and attendance. Higher levels increase the member cap (max 30 at level 11+).

Level	EXP Required	Max Members
1	250	20
2	500	21
3	1,000	22
4	1,500	23
5	2,000	24
6	3,000	25
7	4,000	26
8	6,000	27
9	8,000	28
10	10,000	29
11	13,000	30
12	17,000	30
13	22,000	30
14	28,000	30

17	70,000	30
18	98,000	30
19	133,000	30
20	150,000	30

Total EXP to max: 656,250. Member cap reaches 30 at level 11 and stays there.

Attendance

Members earn rewards by checking in. The first check-in each day is the basic reward; additional milestones grant bonus rewards as cumulative attendance grows.

Days	Type	Guild Points	Guild EXP	Gold	Coupons
1	Basic	10	10	100	10
3	Bonus	—	5	100	10
5	Bonus	—	5	150	15
10	Bonus	—	10	200	20
15	Bonus	—	10	250	25
20	Bonus	—	10	300	30

Each attendance milestone also awards Gold (currency). Bonus milestones stack with the daily basic reward.

Donations

Members can donate resources to the guild up to 3 times daily per type. Each donation step costs more but gives the same rewards. Donations generate Silver Guild Coins (guild treasury) and Guild Coupons (personal).

Resource	Cost (1st / 2nd / 3rd)	Silver Coins	Coupons	Guild Pts	Guild EXP
Gold	3,000 / 5,000 / 7,000	100	10	5	5
Certificates	15 / 15 / 15	50	5	10	10
Stellagems	30 / 40 / 50	100	10	20	20

Silver Guild Coins are spent in the Manager Shop (guild-wide purchases). Guild Coupons are spent in the Member Shop (personal purchases). Values shown are per donation.

Guild Defense

Guild Defense is a seasonal PvE boss mode with 3 rotating seasons, each containing 6 stages. All stages are solo (1 party), boss kill mode, with a 50-turn limit. Each member's score contributes to both personal and guild point totals.

Stages

Stage	Level	BP	Base Pts	Boss Kill	Elite Kill	Mob Kill
1	45	8,300	1,500	500	100	100
2	120	21,000	1,500	1,000	100	100
3	175	29,500	1,500	1,000	200	200
4	400	64,500	1,500	2,000	200	200
5	665	105,500	1,500	2,000	400	400
6	1,047	164,800	1,500	4,000	400	400

Stages are identical across all 3 seasons. Score = Base + Boss Kill + Elite Kill + Mob Kill points per enemy defeated.

Seasonal Buffs

Each season features a promoted special buff and 4 normal buffs. You select one before entering a Guild Defense battle at no cost.

Star Link

Star Link is an HQ facility that synchronizes the levels of multiple Saviors. Unlocked after completing Episode 3, Stage 15.

How It Works

Your four highest-level Saviors are automatically assigned as the main slots.
The Star Link Level equals the minimum level among those four main Saviors.
You manually assign other Saviors to registration slots to sync their level to the Star Link Level.
Linked Saviors cannot be leveled individually — their level is controlled by the link.
Removing a Savior from a slot returns them to their original level.
The system supports up to 50 registration slots.

Facility Upgrades

Upgrading the facility adds registration slots. Each upgrade costs 10 Star Link Facility Cores.

Level	Bonus	Cost
1	Base facility	—
2	+3 slots	10 Cores
3	+3 slots	10 Cores
4	+3 slots	10 Cores
5	+3 slots	10 Cores

Additional slots beyond these 12 can be unlocked with Stellagems (free gems used first), up to a maximum of 50 registration slots.

Star Link Amplification

When your Star Link Level reaches 200 (all four main Saviors at level 200), Star Link Amplification unlocks. The four main Saviors become fixed at level 200 and can no longer be leveled individually.

How Amplification Works

You spend resources to raise the Star Link Level itself (200 → 201 → 202, etc.).
You are not leveling individual Saviors — the Star Link Level increases for all linked Saviors at once.
Every Savior in a registration slot automatically has their level set to the current Star Link Level.
Amplification grants growth stats — all Saviors receiving the shared level gain stats proportional to the amplified level.

Max Level Formula

Max Level = Max Savior Level + (Saviors Owned × 1.25) + (Total Limit Breaks × 1.25)

Owning more Saviors and performing more Limit Breaks raises the amplification ceiling. You can check the current max via the Star Link facility.

Stats gained beyond Level 200 through Star Link Amplification do not apply to boss battles (Cosmo Gate). PvP modes also have separate stat scaling — Ranked Arena ignores Star Link bonuses entirely, while Async Arena halves them.

Amplification Costs

Each amplification level costs Gold, Operation Reports, and Starlight Essence. Costs increase at higher tiers. Data available for levels 200–349.

Level	Gold / Lv	Op. Reports / Lv	Starlight / Lv
200–219	2,842,500	18,582,300	9,360
220–229	2,842,500	18,582,300	9,360–11,700
230–249	2,842,500	18,582,300	11,700
250–279	3,411,000	22,298,760	14,040–16,380
280–299	3,411,000	22,298,760	16,380
300–349	4,127,310	28,207,931	20,720–25,900

Levels 350–700 exist in data but have placeholder costs (not yet released).

Cumulative Costs

Total resources needed to reach each milestone from level 200.

Target Level	Total Gold	Total Op. Reports	Total Starlight
225	73,905,000	483,139,800	245,700
250	145,536,000	951,413,760	540,540
275	230,811,000	1,508,882,760	893,880
300	316,802,310	2,072,260,931	1,307,720
325	419,985,060	2,777,459,206	1,848,512
349 (current max)	519,040,500	3,454,449,550	2,426,600

Slot Rules

Main Slots (4)

Auto-assigned to your 4 highest-level Saviors
Their minimum level sets the Star Link Level
These Saviors can still be leveled normally
Once amplification is active, these 4 become fixed

Registration Slots (up to 50)

Manually assign Saviors to sync to Star Link Level
First 12 slots from facility upgrades, remaining via Stellagems
Each slot can be: empty, locked, or occupied
Removing returns the Savior to their original level
Saviors not assigned to a slot are unaffected

Level Reset

You can reset a Savior's level back to Level 1, refunding all materials that were used for leveling.

Cost: 10 Stellagems per reset.
Available from: Savior Lv. 2 and above.
Refund: All leveling materials (Gold, Operation Reports, Starlight Essence) are returned.
Resonance: Enhanced Resonance Grades will be locked until the Savior reaches the required level again.
Star Link: Saviors currently receiving shared levels through Star Link cannot be reset.

System Interactions

Tactics: Some Tactics enhancements require a minimum Star Link Level to unlock.
Cosmo Gate: Stats gained from amplification beyond Lv.200 do not apply in boss raids.
Resonance: Removing a linked Savior may lock Resonance Grades that require the synced level.
Limit Break: More Limit Breaks across all Saviors raises the amplification max level ceiling.
