Potion
Potion is an item found in Kingdom Hearts and Kingdom Hearts II that restores HP, but in slightly different ways in each game. In the first game, it restores 30 HP for one party member, while in the second game it restores 40% of the one party member's HP. In both games, it can be equipped for use in battle.
In Kingdom Hearts, they can be found in various chests and Trinities scattered throughout the Worlds, as well as purchased in the Traverse Town Item Shop. In Kingdom Hearts II, they can be found in a few select chests in Twilight Town at the beginning of the game; a few are also found by Roxas in the simulated town. Potions can also be purchased at shops in Hollow Bastion and Twilight Town, as well as the Moogle shops throughout the game.
Potion is also a card in Kingdom Hearts: Chain of Memories.
