Hint: Always, always, always use wound on bosses. It makes a huge difference. Also, leech is a very good spell to use. It will help you deal extra damage and heal yourself. Stun is also pretty nice since it disables all damage coming at you, it's probably best to use when an enemy is charging up an attack. Head cracker isn't worth the rage, and neither is strong attack. Stick to stun, leach, more rage, and wound and you'll be able to glide through bosses. Hope it helps!
Man, I love this game. I've played it so many times, and yet each time it seems original and fun. I'm lovin the into and the upgrade system. The only real problem I see is the annoying voice acting in general. Still a great game. 5/5
