I'm running a Fighter build based on a valkyrie from Norse mythology. Skills are Warfare, Polymorph, and Hydrosophist. Bull Horns and Spread Your Wings from Polymorph tree and healing spells from Hydrosophist. Roll the Warfare skill however you like to fight. Leech and Hot Head for the first 2 talent points. I'm having a lot of fun with the character. High mobility and hits like a train.
