How to Fight the Secret Boss Penance
Defeat all Dark Aeons to unlock a new super boss, Penance. His main body has 12,000,000 HP, and he has two arms 500,000 HP each that regenerate when destroyed. Penance requires both arms to perform his most devastating attacks, so take down the more dangerous left arm before focusing on the body.
Penance follows a very predictable attack pattern that switches up slightly once he losses about three million HP. As long as all of your party's stats are maxed out at 255, you can win this battle with a bit of patience.
Like all other enemies, Penance can be killed instantly with Yojimbo's Zanmato ability, but the chances of this happening are very low.
