Shadow walker dies twice - This trick only works if there is a template from the Book Of Life directly next to a Shadow Walker. Try not to touch the template before you kill the Shadow Walker. Jump on the Shadow Walker three times. While you are in the air from the third jump, go toward the template. Take it, and the Shadow Walker will die twice.
