It's not easy to beat him alone, even a low level friend can be a great help. Especially a fire wizard. Fire Elf will keep his cheat occupied for 3 rounds so you can blade up. If you're doing it alone, load up on low/mid-level spells for your school and some TC Fire Elf.
What school are you? For Ice, tower shield until you can do snow angel then do a lot of wand hits until you have blizzard.Then the minion should be dead. After that blade, shield, attack with mammoth. For Storm, spam tempest until minion is dead then shield and blade then attack with levy or triton. For Fire, shield, blade, rain of fire. Minion should be dead then shield, shield, blade, blade then efreet. For Myth, shield, blade, use aura that boosts your attack then use frog. After that blade up and shield then attack with medusa. For Death, use feint, blade, then use scarecrow. Use feint again and death blade, after that use Dr.Von. For Life, blade up, shield, then attack with forest lord, again use an aura that boosts your attack. Then just blade up shield then attack with Gnomes. For Balance, well spam sandstorm then blade up, if your health is lower then 1500, use fairy or satyr then feint and use chimera if you have, if not buy the tc.
