Well, you have very low hit chance and dodge in melee combat, no hit chance and dodge at range, and weak willpower. You also only move one tile at a time. I'm not sure about the damage, but it doesn't seem like fists do much damage, so +20% will be a drop in the ocean. So, you level up very quickly, take little damage from elements, and are relatively durable, but you can't damage opponents almost at all.
