Wrath of Darkness
Wrath of Darkness (闇への流出 Yami e no Ryūshutsu , lit. "Bleeding into Darkness") is a technique in Kingdom Hearts Birth by Sleep Final Mix. It is inserted into the hero's deck if they stand still for too long in one of No Heart's pools of darkness.
Wrath of Darkness allows the user to fire a single orb of darkness at an opponent. If it hits an opponent, it deals minor damage, but also inflicts a status effect on the user.
Mechanics
In Kingdom Hearts Birth by Sleep Final Mix, Wrath of Darkness is a Command that replaces one slot in the Command Deck, has a normal reload time of 4 seconds, and fills the Command Gauge by 5%. Each time it is used, it will inflict a more cumbersome status effect on the protagonist, starting with Blindness, then progressing to Confusion, Poison, and finally, Doom. It cannot be retained outside of the No Heart boss battle.
