The battle system of Golden Sun is pretty much alike with other Turn Based fighting games. You can have up to 4 party members, and each member only can take 1 turn.
 Battle Commands
 Regular Commands
Fight leads to the secondary commands.
This command allows you to switch out members. You can't do this until the 2nd game, once you have met Isaac and party.
Flee is an option that allows you to run away. You will not gain and coins or experience for this. You cannot flee from Bosses and the Battle Arena.
This option allows you to look at the status of each party members.
 Secondary Commands
Attack is basically doing normal attacks with weapons. These can lead sometimes to the weapon howling, and releasing a special attack.
This allows you to use special skills as adepts. It uses up PP, and comes in different elements depending on what Djinn are attached to a member.
Djinn allows you to summon your Djinn to use.
Summon allows you to use Djinn who are in set so you can use them to summon powerful creatures. The summon that you want to use is depending on how many Djinn are in "set". Each summon can either heal you, or damage an opponet. Each has some special effect that they can use to either help you, or hurt the opponet.
The Item command allows you to see the inventory of that Adept and select and item to use. Unusable items will be shown in yellow, usable items in white, and broken items in red.
This allows you to do absolutely nothing during that turn, but cuts the damage your Adept takes in half.
