The only tip I have for this fight (we almost beat him last nite) are:

-Once you reach the room of ogre position everyone on their respective spots and let only the tank/s trigger the cutscene, that alone saves teh CONs from using a curaga 2 on the whole party to heal from te starting firespit.

-If you want to punch the living crap out of him DO NOT DO IT FROM BEHIND unless you wanna get buttstomped to death, position yourself on THE SIDES of teh ogre to avoid him using his buttstomp.
