Lv1 through the whole game, sadomasochism at it's finest. Good luck on next run. Personally, I will wait for the complete game to give it a try ;P
You can theoretically try it with lv 1 cleric archer, with coat weapon + cleric spells for saving and attack throws and maxed out dexterity. Not too sure how it will work on lv 1 (: Usually not much hits you though if you're a cleric.
