Notes
- The Special damage boosting effect of Logic is not affected by the weapon-triangle, and includes the increased Atk from skills like Blárblade+ in its calculations.
- The Special damage boosting effect of Logic can be reduced by damage-reduction effects such as Archrival, A/S Rival Break, 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 using attack damage preventing effects can neutralize damage dealt from the foe's own attacks and the unit's attacks (Units with Umbra Burst weapons will take and deal the minimum 1 damage).
- For more information, see Damage calculation.
- "If unit initiates combat" means if the user starts combat during the player phase. The unit does not need to deal damage, nor be the first to attack.
- However, if the effect is applied after combat, the unit must also survive it to fulfill this condition.
- The Special "reduces damage by X%" effect is calculated after offensive Specials and damage boosting effects such as Arcane Thorn and Change of Fate.
- If an effect such as Miracle or Roy: Of Binding's boosted Special effect 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 uses attack damage preventing effects, 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.
- Special "reduces damage by X%" effects cannot 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.
- Logic's Special cooldown count reduction that occurs during combat is a flat -1 and is not affected by effects related to Special cooldown charge such as Guard, Special Cooldown Charge +1, and Tempo Echo.
- All flat cooldown count increases and/or reductions during combat will stack with each other if they trigger at the same time.
- For example, if a unit has Preempt Pulse and Hush Spectrum, the effects will stack and the unit's cooldown count will neither increase nor decrease.
- All flat cooldown count increases and/or reductions during combat will stack with each other if they trigger at the same time.
- The extra damage boost and special cooldown count -1 effects of Logic will activate if the foe receives a 【Penalty】 effect.
- The extra damage boost and special cooldown count -1 effects will not be negated if the foe receives a 【Bonus】 effect.
- If the foe does not receive a 【Penalty】 effect, or has their 【Penalty】 effect removed by a source of Penalty effect removal, the extra damage boost and special cooldown count -1 effects will be negated.
- For more information, see Status effects.
