Additional Damage

Additional Damage (commonly referred to as “DoT” and “bleeding damage”) is a debuff that deals damage to afflicted enemies at the end of the turn. This debuff cannot be cleansed unless it is purged.

Additional Damage can be reduced with Additional Damage Reduction.

Interactions with Gradual Healing
This effect will always occur before Gradual Healing takes effect, making it a common strategy and a necessity to use Gradual Healing to counter Additional Damage.

Interactions with Turn’s End to Start Effects
Unlike Gradual Healing and Gradual BB Gauge Boost, DoT will always occur at the end of the turn and cannot be manipulated by any means. It is highly advised to not use Turn’s End to Start effects, as units will become highly vulnerable without utilizing Gradual Healing to survive the incoming attacks on the following turn.

Interactions with Shields
Shields take damage from Additional Damage rather than the unit's HP. Should the shield wear off as a result of Additional Damage, the remaining damage

Formula
DoT = [(UnbuffedATK x (DoT% + 100)/100) - (TotalEnemyDEF/3)] * Element Mod * (100 + DoT dmg% - DoT Mitigation%)/100

UnbuffedATK = Base ATK + DoT Flat ATK + Imp ATK

TotalEnemyDEF = Enemy DEF after all buffs

Element Mod = 1.5 if strong element, 0.5 if resisted element, 1.0 otherwise (unaffected by EWD)

Trivia

 * “Additional Damage” is known to cause major confusion, as it does not mitigate damage like Damage Mitigation and Elemental Mitigation do.
