Note The master necromancers are physically frail yet dangerous because of thier necromantic arts, but unlike apprentices they don't have to rely only on that.

Also note that the crystal skulls found in master necromancers' inventories are the only way how to get one, apart from [[Scroll of Change Material|transmuting]] a normal bone skull into a [[:Category:Light Crystal|light crystal]].
