Golden Sun: The Lost Age Tips

Beating The Doom Dragon
First you have to be at least on level 40 or higher. Then start the match with Jenna, Isaac, Felix, and Sheba or Ivan.

First power up Felix and Isaac with Impact. Use Cool Aura with Jenna every turn. And normal attack with Isaac and Felix (Have one equiped with the Sol Blade and the other with the Excaliber). Once fully powered then start using resist to prepare for the Cruel Ruins. And you`ve got the match.

It always work. I fight it every day. Also never release your Djinn!
