Parch

The Parch Psynergy is a Utility Psynergy introduced in Golden Sun: The Lost Age. It is learned by Piers and Piers only at one specific, mandatory point in the game: when the party reaches the end of the Aqua Rock dungeon and interacts with the magic tablet that would bestow the Mercury Psynergy onto a Mercury Adept. Piers can use Parch to evaporate and effectively remove small bodies of standing water within dungeon-style environments. In addition to being required to complete the game, particularly being required to enter Tundaria Tower, this Psynergy is needed to get to the Coatlicue summon tablet.
