Notes[ | ]
- The damage-reduction effect is calculated after offensive Specials and damage boosting effects such as
Arcane Lúin and Dominance.
- If a skill such as Miracle or Everliving Domain can trigger, the damage-reduction effect will not trigger and the user will still survive with only 1 HP.
- "Reduces damage by X%" effects stack multiplicatively, unlike interactions related to the weapon-triangle, such as Triangle Adept and the weapon-triangle advantage boost.
- Special "reduces damage by X%" effects cannot be neutralized or reduced by effects such as Share Spoils or Halves non-Special damage reduction.
- For more information, see Damage calculation.
