Ravenloft challenges would end up with some pretty neat gear, you could expect the following to be common!

*Vampirism
*Disruption
*Solar damage effects
*Holy damage effects
*Invisibility Guard
*Nightmare guard
*Silver
*Necromancy assist items
*Turn undead assist items
*Healing amp items

Hell they might even have a silver bastard sword with vampirism, constitution damage, bludgeoning damage, force damage, paralysis, and a red augment slot!
