At the start of combat, if unit's Special is ready and unit's Spd > foe's Spd, reduces damage from attacks during combat by percentage = difference between stats × 3 (max 30%).

Notes[]
- The Special damage boosting effect of Vital Astra can be reduced by damage-reduction effects such as
Gust, Atk/Spd Excel, and Dodge.
- Damage boosting effects stack additively, similar to flat damage-reduction effects and interactions related to the weapon-triangle, such as Triangle Adept and the weapon-triangle advantage boost.
- A foe equipped with Invincibility Seals will neutralize all sources of damage except from Røkkr area-of-effect Specials and the minimum 1 damage from Umbra Burst weapons.
- A foe equipped with Invincible Sister will neutralize all sources of damage during combat except for the minimum 1 damage from Umbra Burst weapons only once per Phase after it triggers.
- A foe equipped with Vengeful God will neutralize all sources of damage during combat except for the minimum 1 damage from Umbra Burst weapons only once per Phase after Miracle triggers if that foe's HP ≥ 25% at start of combat.
- For more information, see Damage calculation.
- Damage boosting effects stack additively, similar to flat damage-reduction effects and interactions related to the weapon-triangle, such as
- The non-Special "reduces damage by X%" 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.
- Umbra Burst weapons will always deal a minimum of 1 damage even if the foe is equipped with
Invincible Sister, Vengeful God, Invincibility Seals, or damage reduction effects. - "Reduces damage by X%" effects stack multiplicatively, unlike interactions related to the weapon-triangle, such as Triangle Adept and the weapon-triangle advantage boost.
- Non-Special "reduces damage by X%" effects can be neutralized or reduced only during combat by effects such as Share Spoils+ or Halves non-Special damage reduction.
- For more information, see Damage calculation.
- If a skill such as
- The Area-of-effect Special damage-reduction effect is calculated after Area-of-effect Specials and damage boosting effects that trigger before combat such as Treachery and Dominance.
- Røkkr area-of-effect Specials will always deal out of combat damage even if the foe is equipped with Invincibility Seals or damage reduction effects.
- "Reduces damage by X%" effects stack multiplicatively, unlike interactions related to the weapon-triangle, such as Triangle Adept and the weapon-triangle advantage boost.
- Non-Special "reduces damage by X%" effects that reduce damage from Area-of-effect Specials can be neutralized or reduced only out of combat.
