Arc-Fort Breath

Inflicts Atk/Def-4 on foe, unit deals +X damage (excluding area-of-effect Specials; X = the greater of 15% of unit's Atk or 20% of unit's Def), and grants Special cooldown charge +1 to unit per attack during combat (only highest value applied; does not stack), and also, when unit's Special triggers, neutralizes foe's "reduces damage by X%" effects from foe's non-Special skills (excluding area-of-effect Specials).
