Shattering Stars/Beastmaster

Beastmaster
Not too hard. Bring along a Panzer Ghalad for this fight along with the usual Opo-opo necklace, sleep potions, hi-potions and some def up food (I personally like fish chiefkabobs as a dedicated tank but it's up to you). Okay, sleep yourself to 100% TP, summon your pet and sic it on Maat while you fight Maat's pet but don't use your WS on Maat's pet, that's for Maat himself. once you kill Maat's pet, run out of range, heal yourself back up with hi-potions and let your pet fight Maat to the death. Now run in and hit Maat with rampage. That should send him packing. (as for your 2hr, I suspect using it will prompt Maat to use his as well which could give you trouble. If you don't need to use it, then don't. No need to risk it)
