Notes[]
Main article: Skill interaction
- The HP threshold applies both to the guaranteed follow-up attack and the bonus neutralization.
- The HP threshold is checked at start of combat, and the skill either applies throughout the entire combat, or not at all.
- "If foe initiates combat" means if a foe triggers combat during the enemy phase. The unit being initiated upon does not need to deal damage, nor be able to counterattack.
- However, if the effect is applied after combat, the unit being initiated upon must also survive it to fulfill this condition.
- Wily Fighter can neutralize
Bonuses during combat.
- Bonuses are neutralized by inflicting temporary debuffs of the same amount during combat.
- The Bonus neutralizing effect will be negated if the affected unit has Panic (and doesn't have Null Panic), or has their Bonuses removed by a source of Bonus effect neutralization.
- As a general rule, if a unit is both prevented from making, and guaranteed to make a follow-up attack, the effects cancel out, and the Spd difference decides instead (including effects that alter the Spd difference such as Frozen).
- A foe with effects such as Phys. Null Follow or Null Follow-Up will neutralize the guaranteed follow-up attack granted by Wily Fighter.
- The stat reduction that can be applied during combat by Wily Fighter 4 is considered a temporary debuff.
- The damage boosting effect of Wily Fighter 4 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.
- 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
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. - 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 flat damage-reduction effect is calculated after offensive Specials, damage boosting effects such as Arcane Lúin and Dominance, and "reduces damage by X%" effects such as Gust and Dodge.
- 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.
- Flat damage-reduction effects stack additively, similar to damage boosting effects and interactions related to the weapon-triangle, such as Triangle Adept and the weapon-triangle advantage boost.
- Flat damage-reduction 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.
