Djinn are a type of species in the video game Golden Sun. Once your team finds one, you will have to battle the Djinn for it to join your team. Djinn will help you throughout the game during battles and other incidents. There are four different types of Djinn, each one with its own abilities. If a Djinn in your party is on STANDBY, you are then able to summon the selected Djinn for battle. Though if he is not on Standby, then it will give the selected party member much better stats then before.
