After killing animals in Two Worlds, they come back in "ghost" form. When you create a multi-player game, kill an animal and teleport to another area. Come back in roughly three to five minutes to give the animal time to "respawn" as a ghost. Aggro this ghostly animal and have him chase you into a town. This animal cannot be killed with normal weapons, and the guards will attack the animal because it is chasing you. Let the animal kill the guards and you can loot them without dying.
