Notes

• The damage dealt as combat begins ignores the foe's Def or Res, and cannot be reduced by damage-reduction effects such as  Gust,  Atk/Spd Excel, and  Dodge.
  • The damage dealt as combat begins cannot reduce a unit's HP to 0.
  • Units with effects such as  Breath of Life 4 or  Divine Nectar will recover HP after damage dealt as combat begins.
  • A foe equipped with  Embla's Ward,  Múspellflame,  Niðavellir Axiom,  Gold Perfection, or  Nine-Realm Pact will neutralize all sources of damage except from Røkkr area-of-effect Specials and the minimum 1 damage from Umbra Burst weapons.
  • For more information, see Damage calculation.

• The damage boosting effect of Resonance ignores the foe's Def or Res when calculating the damage boost, and can be reduced by damage-reduction effects such as  Gust,  Atk/Spd Excel, and  Dodge.
  • A foe equipped with  Embla's Ward,  Múspellflame,  Niðavellir Axiom,  Gold Perfection, or  Nine-Realm Pact will neutralize all sources of damage except from Røkkr area-of-effect Specials and the minimum 1 damage from Umbra Burst weapons.
  • For more information, see Damage calculation.
• Resonance will reduce the effect of non-Special "reduces damage by X%" effects from Specials such as  Vital Astra.
  • Damage-reduction reducing effects stack multiplicatively, unlike interactions related to the weapon-triangle, such as  Triangle Adept and the weapon-triangle advantage boost.
    • For example, if a unit has  Halves non-Special damage reduction and a foe with  Dodge is on a space with 【Divine Vein (Water)】, the maximum total damage-reduction is reduced to 10%, since the two effects reduce the damage to (1 − ((40% − 50%) − 50%)) = 90% of the original damage instead of 60% of the original damage.
  • Each damage-reduction effect is reduced individually.
    • For example, if a unit has  Halves non-Special damage reduction and the foe has both  Spurn 4 and  Dodge, the maximum total damage-reduction is reduced to 40%, since the two effects reduce the damage to (1 − (50% − 50%)) × (1 − (40% − 50%)) = 60% of the original damage instead of 30% of the original damage.
  • Resonance will not reduce the effect of Special "reduces damage by X%" effects such as  Gust or  Laguz Friend 4.
  • For more information, see Damage calculation.
• The stat decrease that can be applied by Resonance 4 is considered a temporary debuff.
