I'm a new player and I've been looking at some of the pale master stuff for wizards using the character creation tool, and I got to say, it looks like a blast. I don't see many players using it though... is it nerfed in some way in terms of damage? Also, I can't really tell what the "negative energy spells" are and how pale masters are supposed to use being healed by negative energy to their advantage. Also, are their any particular builds that are recommended?
