Once More (コンボリーヴ Conbo Rīvu?, lit. "Combo Leave") is an ability available in Kingdom Hearts II, Kingdom Hearts II Final Mix, Kingdom Hearts 358/2 Days , Kingdom Hearts Birth by Sleep, Kingdom Hearts Birth by Sleep Final Mix, and Kingdom Hearts Re:coded. Once More ensures that the player will retain 1 HP after being attacked by a combo that would normally finish them off. However, if the player already has 1 HP, Once More will not save them from defeat. In Kingdom Hearts III, this ability is translated as Withstand Combo. Another ability similar to Once More is Second Chance.
