This runthrough of Golden Sun's bosses will be a unique one, in that they will all use different classes than the norm. Most playthroughs just stick to default classes, so this will make it interesting.
While he is technically the second boss and Tret is the first, you can't really progress the story until the Mercury Lighthouse, so I usually hit Saturos up first. Makes a hell of a fight, better than Tret.
At these levels, I feel like this is the best set-up for Saturos. Issac has Cutting Edge, a Water psynergy based on the attack stat, so that's extra damage to Saturos, as well as Ply for Back up healing. Garet has Heat Wave for more damage, also Forge to boost attack. Mia has Impact for buffing, then goes to secondary healer or damage dealer. Ivan is the primary healer.
Not too challenging, but an Eruption focused on Mia or Ivan could kill them in one hit.
