I went with the Mana Leak strategy. Started with a Trisword, a Bear Mace and a Strength Potion and bought a Wharrgarbl in the dungeon. Converted as many glyphs as I could find except for fireball, then worshipped Mysty early and built up piety while revealing the whole map, then killed the goat and hit Mana Leak. Then I killed a Wraith to level up. Once i leveled, I hit the boss with fireballs until I ran out of MP, then leveled again. Repeated this until I could survive a hit from the boss, then I'd hit him and level up for as long as I could. Lather, rinse and repeat until everything's dead.
