Rather than adding a bunch of pointless spells I was thinking of adding something a little more in-depth. Granted I'm not sure how it would be coded into the game but in theory I think it might make necromancers happy.
What I was thinking of was giving necromancers a skill or spell that works with creating a Homunculus, or some other kind of magical creature similiar to a familiar.
This wouldn't be just walking around raising every corpse you can find skill. This could involve collecting ingredients scattered around the world to create a magical being you intend to be your companion or in the evil necromancer's case. Your little servant bitch. Making the skill in-depth as to produce different results based on the ingredients used and the level of the spell caster the creature would function similiar to a pmount. Allowing it only to be in groups the necromancer leads, if it dies repoping at the said necromancers house (laboratory) or if they don't have one, the creature would be slain permanently. If you did have a place for it to go it would be injured when it comes to there and you would have to go out and find more ingredients to repair it creating hybrids etc. Or something along those lines.
Now of course this being would be able to be ordered around and hopefully level up and gain strength as it battles with it's master. I was thinking it could have a limited number of spells/skills it can used based upon the ingredients etc. I don't have it all thought out yet and I'm not even sure if something like this was brought up before and I'm too tired and sick to check right now. Anyway give your thoughts on this I'm not sure if necromancers would like something like this or if they would deem it worthless.
