Endless Magic (エンドレスマジック, Endoresu Majikku?) is an ability introduced in Kingdom Hearts II. It allows the user to string powerful magic combos together in rapid succession, disabling magic combo finishers.
In Kingdom Hearts II, Endless Magic is a support ability. While in Master Form, magic combo finishers are unavailable. As such, Sora may continuously string spells together for as long as he has MP. He is also free to transition out of the rapid-casting with his physical combo finishers.
In Kingdom Hearts III, Endless Magic is a support ability that disables magic combo finishers.
