Real easiest way: fight lvl. 100 Exdeath, have Mimic (I think it was) equipped. He's pathetically easy to avoid, so you just have to let him hit you with a couple Bravery attacks to have him get 9999 Bravery, then use Mimic to copy his Bravery, then use an HP attack to finish him off. It's not even a challenge to beat him with a level 1 character.<br/><br/>
