Can we please have one of the paths of the Necromancer be a Death mage. A mage that focuses on spell of the realm of death?
We could have spells like pain, a AFF spell that only affects living. Perhaps with a low 10 % chance to cause 1 round lag, due to victim contorting in pain spasms.
Some corpse spell. A spell that either makes corpse objects in room either explode for AoE damage, or poison smoke liek ninjas.
Control undead. A spell that lets you charm undead. Liek DK charm.
Some form of "Dispel Undead" A necromancer master of undead should know how to harm the magic suporting undead constructs.
Draining. Allow this path to cast and inflict the Drained affect.
Perhaps have a spell that allows you to summon for 0-1 hour a ghost to aid you in combat as a Pet.
A spell that allows you to temporarily transform yourself into undead like. Not really undead, just undead like. Disease/hunger/thirst immunity + holy vuln. Perhaps make it last long and consume a soul.
Perhaps an enervation spell that would effectively lower that person level for a time. (Probably to hard to code.)
The Fear spell.
A pet slaying spell that is save or die (Like isolate) but that doesn't cost 200 mana and 2 rounds lag.
