Extreme is a ring panel synthesizable in Kingdom Hearts 358/2 Days. Roxas must have the Legend Rank, which requires completing Story Mode.

Ingredients

 * 1 Orichalcum
 * 8 Moonstone
 * 20 Dark Ingot
 * 4 Luck Tech

Effect
When equipped, the wearer has only 1 HP and cannot gain any more, but greatly increases gained EXP (2x as much is gained).

Although having only 1 HP seems very risky and dangerous, some players actually take advantage of the 1 HP rule by using Limit Breaks when surrounded by a group of enemies or against bosses.
