Ether

The Ether (エーテル) is an item that restores 3 MP or magic points in Kingdom Hearts. However, in Kingdom Hearts II it fully restores MP (if there is some left in the bar) or it can be used to reduce the MP Charge Gauge. In Kingdom Hearts Chain of Memories and Kingdom Hearts Re:Chain of Memories, an Ether card quickly reloads all magic cards. In Kingdom Hearts 358/2 Days, it's in the form of an item panel which restores one cast of each magic you've installed. In Kingdom Hearts Birth by Sleep, it restores 30% of the user's Focus Gauge. In Kingdom Hearts Re:coded it raises Data-Sora's clock level by one.
