Victim said:Don't liches come standard with a negative energy touch attack that could be used for healing his undead form?
Good point. It doesn't make sense to me for a creature to recharge its undead life force with its undead life force, but the way the rules are written, this should work.
I like the Negative Energy Burst spell, from Tome and Blood. Don't know if its been converted officially in a 3.5E book, though.
