When in two player mode with Dorn and Ysuran, after raising both their classes by doing the special side quests in Chapter 3, get Animal Friendship for Dorn and Shadow Conjuration for Ysuran. Get full ranks in both. Cast Animal Friendship on Ysuran's Shadow Creature for double damage from its attacks, This works especially well when battling foes around corners. You can send him around and he will attack with extra damage, and you will not get hit at all. This is especially useful in extreme mode because of the increased difficulty and creature damage. Note: This also works with the summoned undead Also, it only works if the Shadow Creature is moving.
