This is the PSP version exclusive super boss.

A grandiose looking fight for sure, but not really that difficult.

The worst part by far is having to level 15 characters to around level 55.

First part is the chest and a hand, it's probably the worst part. Lot of nasty abilities. I would put your second strongest party on this part.

Second part is the head, chest, and yet another hand. If you kill the hand first it casts Reraise on itself, so kill the head first.

It can summon weak normal monsters, kill them when they get summoned. Your weakest party should be on this one.

Final part is the CPU and a bunch of nodes. Unlike CPU in the Depths, you should kill all of the nodes on this fight. Once all of the nodes are dead, CPU will heal itself for significant amounts of damage every turn. Due to this, put your strongest party on it, so you can overwhelm it with damage.
