Supplemental Damage refers to damage that is added to certain damage instances. The generic status associated to supplemental damage is DMG BoostedDMG dealt is boosted
.

Supplemental damage activations follow certain rules:

• DMG BoostedDMG dealt is boosted
  is applied additively to each damage instance.
  • Skills that hit foes for multiple times (e.g.  Stardust10-hit, 80% Fire damage to a foe (Damage cap: ~82,000Does not include Peacemaker. per hit).
    At level 95:
    Also gain 30% Bonus Fire DMGDeals bonus fire DMG for one-foe one-ally attacks
    Strength: 30%Duration: 2 turns and Guaranteed TAGuaranteed Triple Attack regardless of Triple Attack Lowered debuffs
    Duration: 2 turns.) will apply the supplemental damage per damage instance.
  • Every Bonus DMGDeals bonus DMG for one-foe one-ally attacks
    instance will be treated as a separate damage instance.
  • Charge Attacks are treated as a single damage instance, even if the extended animation shows multiple hits.
  • Certain characters will show multiple damage instances per normal attack (e.g. Ilsa). For Supplemental Damage purposes, these are treated as a single damage instance.
• DMG BoostedDMG dealt is boosted
  typically ignores DMG Cuts, except for 100% DMG Cut and is not affected by soft capping mechanics.
• DMG BoostedDMG dealt is boosted
  is boosted by any multiplier that increases Final Damage (e.g. Seraphic multiplier).
• DMG BoostedDMG dealt is boosted
  is applicable to the following:

• The supplemental damage value usually has a cap, and it is dependent on the source of the effect. However, the actual damage is usually based on a formula , which can take different forms, for instance:
  • Based on a percentage of the enemy's maximum HP, such as Sandalphon (Event)'s  The Power of OneAll allies gain 30% / 50% Critical Hit Rate UpDMG is slightly boosted for critical hits
    Strength: 30% chance of dealing 50% more damage.Duration: 3 turns and DMG BoostedDMG dealt is boosted
    Strength: 1% of enemy's max HP (Damage cap: 10,000)Duration: 3 turns. skill.
  • Based on a percentage of the initial damage instance, such as Halluel and Malluel's EverbaneBoost to DMG taken / HP is lowered on every turn (Can't be removed)
    Local status effect effect.
    • When two sources of this type are present and stack (e.g. Nightmare ScarletDMG taken is boosted
      Local status effect and EverbaneBoost to DMG taken / HP is lowered on every turn (Can't be removed)
      Local status effect), they stack additively and not multiplically, i.e. the calculation is based on the damage before supplemental damage.
  • Based on the number of debuffs, such as Silva (Light)'s Weak PointDMG taken is boosted based on number of debuffs
    effect.

• Supplemental damage based on different conditions should generally stack, e.g.
  • DMG BoostedDMG dealt is boosted
    , Yuel (Themed)'s Zuigetsu support skill, and
    
     Hollowsky Weapons
    • Hollowsky Staff
    • Hollowsky Spear
    • Hollowsky Axe
    • Hollowsky Bow
    • Hollowsky Blade
    ' Covenant skills can all stack at once.
  • Similar conditions from different sources may stack, (e.g. Hollowsky Blade's Calamitous Covenant and Weak PointDMG taken is boosted based on number of debuffs
    ).
  • Supplemental damage from the same source (eg. DMG BoostedDMG dealt is boosted
    from Kokkoro's Speed Up and Hollowsky Axe's charge attack) will not stack.

• When the supplemental damage is a non-integer, the damage is rounded up.

• A quick way to test stacking for a given setup is to enter a Trial Battle with an empty weapon/summon grid, as the Supplemental damage will represent most of the damage and provide a clearer visual.
