The true necromancer is a new class to me. I read about it in the Manuel and it looked VERY fun, but kinda hard to create an effective AND RP friendly build.
I came up with two different concepts for possible builds, but I want some more input and ideas. I have not yet selected feats and such for builds, but rather have general concepts of what they are like RP wise and how they will play out in the game...
Necromantic Master-
A true master of undeath. A power-hungry dread necromancer who turned to evil gods as a path to greater power, the necromantic master is the ultimate lord of the grave who can both amass a massive army of undead, and strengthen them with his wicked power.
25 Dread Necromancer/5 Cleric/10 True Necromancer
The ultimate necromancer, the cleric levels are basically ignored for the most part and only used as a gateway into the true necromancer class. They can be of some use though, mainly as minor heals(inflect spells) and boosts for your undead and defenses for yourself. However, the real power lies in the combination of the dread necromancer and true necromancer classes. The dread necro can control a massive amount of undead thanks to his undead mastery feat, the zone of animation feat and spells such as plague of undead. The True Necromancer's zone of desecration in turn powers up your undead army. Combined that with some of the minor cleric buffs and perhaps some corpsecrafter feats, you have a VERY scary undead hoard at your command.
Master of Dark Magics
A power-hungry spellcaster who has devoted her life to gaining the greatest magical power possible. Gaining her powers from both the favor of evil gods and vigorous study the arcane arts, she has become a truly frightening caster capable of casting both the most powerful of divine and arcane spells as well as using her dark magic to bolster her undead minions.
23 Cleric/7 Wizard/10 True Nercomancer
This build is much less a "true necromancer" then the first, but in turn for giving up some necromantic powers like zone of animation and undead mastery, this character becomes the ultimate evil caster, capable of casting both 9th level cleric and wizard spells(via scroll learning) In fact, this kind of character, like a normal wizard, has the potential to learn and be able to cast EVERY wizard spell and every cleric spell. Meaning that you have a VERY versatile caster who has power over the undead to boot. Also, a little side note about this build, if you decide you REALLY want zone of animation and undead mastery, then there is a way to do it. Chose Ithlid as your race. The monster bonus to int means you can take less points in it and put them to charisma, and you also get nice charisma and wisdom bonuses of +6, meaning you can essentially do what is impossible for most other races and have three extremely high stats.
The details of said builds are still being worked out, but if you have any other build ideas, please tell.
