However as I already posted I'll still poison him BEFORE fighting Gate Keeper/Zelos even on normal mode via 10x exp BUT on Hard/Mania mode he CAN still kill a lv 200 party in 1 hit but NEVER play as Collete yourself its still better to play ONLY has Lloyd especially on hard mode. As for Regal I'm not good enough to control him so I'll still ONLY use Lloyd (play him your self especially AFTER you poison him) and Collete and BOTH ZELOS and Raine against him I had lv 120 party members against him on NORMAL mode via 10x exp but on hard mode he can still 1 shot a LV 200 party WITH Meteor Storm. For the 20 floors BOOK dungeon since theirs 4 bosses every 5 floors and 0 save points not only is a LV 200 party a MUST for Mania mode so are having AT least 5000 out of 9999 kills for EVERY Devils arm weapon besides Genis/Raine since those don't really work for SPELL damage and even if they did Raine would be ONLY be using Healing spells and Geni sucks their even on normal mode.
