Ingredients

 * Orichalcum x1
 * Dark Ingot x20
 * Moonstone x8
 * Luck Tech x4

Effect
When equipped, the wearer has only 1 HP and cannot gain any more, but greatly increases gained EXP.

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.
