I really like the Dread Necromancer from 3.5's Heroes of Horror, it's been one of my favorite classes for a long time, though I haven't actually gotten to play one before (story of my gaming life). I figured I'd try to work up something for Pathfinder, since that seems to be what I'm playing around here.
I'm trying to do something more original than just a conversion of the original, but retaining the basic pieces of the class that made it my favorite in the first place. Any help or criticism is more than welcome, considering I've never done anything like this.
Basic design goals: In descending order of importance to the class, Hordes of Undead Minions, powerful but very focused spellcasting, and moderate combat abilities for the first handful of levels.
On the Subject of Undead Hordes:- When you aquire Animate dead, the pool you can control is expanded to (HD x 4) + (HD x CHA modifier), like the undead mastery of the Dread Necromancer.
- I'm debating whether I should give my class a straight-up bonus to undead animated by the Necromancer like the Dread Necromancer does, work up some Corpsecrafting-esque feats that are given as free feats every few levels, or some kind of combination of both. Giving the choice of free feats every few levels would help what I see as a little lack of new things in the Dread Necromancer class at high levels.
On the Subject of Powerful but Focused Spellcasting:- The Dread Necromancer had a very focused spell list, almost entirely Necromancy spells, and even the Advanced Learning ability that let the Dread Necro add Wizard or Cleric spells only allowed more necromancy spells. The Dread Necro is a full 9 level class, but I'm wondering if maybe a 2/3rds spellcasting class is more appropriate, most of the Undead-related spells are level 6 or lower, at least on the Cleric spell lists. I think maybe adding Lesser Animate Dead at 2nd level or getting Animate Dead at 3rd level like a cleric instead of 4th like a wizard would make sure the class doesn't get the ability to build it's undead hordes any later than the Dread Necro already does.
- Some of the suggestions on old topics about converting the Dread Necromancer had an idea of the Advanced learning skill allowing you to learn any cleric or wizard spell at a spell level higher than normal. I was also thinking, if moving to a 2/3rd casting class, allowing the 7-9th level necromancy spells as once/day spell-like abilities, or casting having them take up 2 6th level spell slots.
On the Subject of Moderate Combat Abilities:- A big thing I'm thinking of is whether to stick with a d6 HD and slow BAB progression, or to bump it up to Medium BAB/HD. If I went to Medium BAB I think I would restrict spellcasting to a 2/3rds spellcasting like the Magus, though I wonder if staying with an almost totally-necromancer 9-level spell list is enough of a drawback for a medium BAB spellcasting class.
- Some kind of at-will or maybe CHA mod + 3 times a day touch attack of negative energy, like the Dread Necro's Charnel Touch, that is useful as damage at early levels but becomes a way to keep your undead minions topped up on health later on.
Miscellaneous:- Proficiencies? Light armor and Simple weapons? I swear I thought of 1 martial weapon proficiency totally on my own before realizing that's what the Dread Necromancer also does. I'm trying to create something partially original, but it's really hard guys!
I'll post more as I work it out, but right now I think I'm supposed to be cleaning up the apartment before I go to work so my wife doesn't have to do it all herself when she gets home from work before my mom comes for a visit tomorrow.
Any ideas/tips/criticisms are welcome, if anyone can wade through my walls of text.
