Isaac learns Grand Gaia at lv 54.
Another advantage is the specialization of stat bonuses. re: strongest psynergy If you go to the status screen, click on whoever you gave teleport to, then click the A button, you can see what elements the psynergy they have are. Each adept will have +60 in both elemental power and resistance, yielding the strongest elemental psynergy attacks in the game. You have to play Lost Age for that. The strongest psynergy is Call Dullahan, but you can't get that in GS. However, Mother Gaia will likely be the strongest Power-based Psynergy available … Golden Sun: Gaia will only see early game use if Isaac is placed in the Apprentice series; by the time he acquires the four Venus Djinn needed to access it in his base class, it would be outclassed. Garet learns Pyroclasm at lv 51 This setup will yield some very powerful ranged elemental attack psynergy. Double elemental classes reigned supreme in the first Golden Sun game and they are still a great choice.
