I recommend tihs party Sagex2,Magus,Knight. Use one of the sage to spam curage on all. The other one using haste on the Knight first, then spam protect. Magus spam flare. After the second Saga finish spamming protect, if you see the Magus' mp for flare at 1, use an elixer. Continue, then you should win. I tried him at level 57 with my party of Sage,Magus,Knight,(SPOILER)Onion Knight. He was pretty easy.
