Psy Crystal

A Psy Crystal is a consumable item in the Golden Sun series. Like most consumable items, each party member can hold up to 30 psy crystal in a single inventory slot. When used, a psy crystal completely restores a single party member's Psynergy Points. Psy crystals can be bought for 1500 coins and sold for 1125 coins. Also, psy crystals are considered Artifacts, meaning they can be re-purchased if sold or dropped.

Trivia

 * Before Golden Sun: Dark Dawn, psy crystals were the only consumable item that restored Psynergy Points. Even with the new PP-restoring items introduced in Dark Dawn, psy crystals are the only ones considered Artifacts.
