You may want to add a few more rules to go along with the vampire theme. Just a few suggestions:
No potions at all(after life tap); vampire must gain there strength back from leaching. or...
Only red potions; bottled blood; only can be used when found from enemies.
Hmm seems like he may just become a revive necro with life tap and teeth(a slow revive necro).
Perhaps he can only revive those that he has killed himself; transfering the vampiric curse with his bite.
It seems that the idea could use a little fleshing out, but could be lots of fun.
P.S. Maybe allow blood golem in some way; it seems that a vampire would specialize in blood magic.
EDIT: Also make some kind of ruling about mercs, which are allowed, if any, what they can use, ect..
