Elixir

In Kingdom Hearts 358/2 Days, Elixir is in form of an item panel which restore all of your HP and Magic. In Kingdom Hearts Chain of Memories the Elixir card reloads all attack and magic cards. It can be used on the field, in battle and from the Main Menu. They can be synthesized, found in chests and Trinities and are occasionally awarded as prizes for completing certain tasks and quests.
