So, hopefully I'm about to start playing the villian in a heroes vs. villain game. My character will be the BBEG if I get in. The character is a Human Necropolitan Dread Necromancer 19 with a charisma (post-boosts and inherent bonus) of 33, so he can (and will) have a good-sized army of skeles and zombies, making liberal use of Plague of Undead so they have maximum hp (total of 18 per HD, thanks to other boosts as well). I was sure to grab Corpsecrafter, Nimble Bones, Destruction Retribuiton, and Sickening Grasp (mainly for the caster level boost). My Human Bonus feat went to Mother Cyst, so I have access to that line of spells. I do not have any metamagic feats or divine feats (had to sacrifice my only divine feat for Landlord). All of my feat slots are filled. Leadership is a bonus feat for the main villian, but I don't get a cohort. That role is taken up by others playing "henchmen".
Important equipment so far includes the Lyre of the Restful Soul, Rod of Defiance (between the two, undead get -8 turn resistance), Scepter of the Netherworld (so I count as level 22 for Rebuking), and a Rod of Undead Mastery. And a Cloak of Charisma +6, but that's such a "duh" item...
So, with my Plague of Undead/Animate Dead pool alone, I have 578 HD of undead to control. Rebuking I won't calculate specifics on, but anything of up to 19 HD I could (doesn't mean I will) nab.
The final piece of my army creation is something that most necromancers don't have: living minions. Necrotic Tumor is a very nice spell, giving me permanant domination over the subject with the save DC of a 9th level spell, but only a 7th level slot. Did I mention that Protection From Evil doesn't stop this? Yes, I have to affect them with a Necrotic Cyst spell first, but I find that to be a non-challenge. This can potentially let me nab a lot of living allies who can never betray me.
Something I would like to know is what are good targets for each method of "recruiting"? All official books are open, but try and stay away from the cheese.
