Attacks the enemy with a bass. When the enemy is defeated, recovers Health of the caster and grants an extra turn. Penetrates the target’s Defense, and cannot trigger a critical hit. Amount recovered and damage dealt increase proportional to the caster’s max Health. Begins the first battle with full skill cooldown count, and when this skill is unavailable due to cooldown count, at the start of every turn, decreases all skill cooldowns by 1 turn.
