Damage Control

Crisis Half is an ability that only appears in Kingdom Hearts II: Final Mix and Kingdom Hearts 358/2 Days. In 358/2 Days, it can be activated through the abilities of Roxas's and Xion's Fate Rebellion+. In Kingdom Hearts II: Final Mix, it can be used through the abilities of Goofy's Save the King+ and Donald's Centurion+. Oddly, this ability can only be used through upgraded weapons, as shown by the "+" at the end of their names.
