That reminds me, I would assume Rhal can use the standard ReDead abilities, yes? By that I mean the paralyzing scream and life energy draining and whatnot. In fact, it would probably be best to set some ground rules for how that stuff works so it won't cause debates later, yes?

I'm still not sure how the scream will be balanced, but the life drinking thing is likely going to be Rhal's only real means of healing himself. Being an undead creature, I wouldn't expect healing magic or even life potions to work on him, or in fact have the opposite effect (they harm him) a la Final Fantasy.
