Psynergy is a type of magic in the Golden Sun series. There are tons of different types of Psynergy, each with it's own unique ability. One of the first psynergy types you get is titled Move, which allows you to move certain things on screen which will help you progress through the game. You should take note that some psynergy will only be useable during battle, and others while traversing through the game (and not fighting.). Some of the psynergy, however, will be used both during battle, and out of battle.
