A set of spells, mods and other little or not so little tweaks to Skyrim that make being a necromancer all that much more hilarious. From purely cosmetic look of zombies to cost of magicka to new summons, theres oodles to play with for the fledgling lord of the dead. All of these mods are loaded in my copy of Skyrim and function just about perfect, so you can trust they are compatible. Will work with either vanilla Skyrim or with Dawnguard, haven't gotten to testing Dragonborn yet but I've no reason to believe they'll cause issues there either.

Though some do cause effects they wouldn't on their own:
The NPC Hearts and Humans drop Human parts mod sometimes overlap, sometimes not, cant figure out what causes one to overwrite the other but sometimes you get lucky and you get a whole slew of drops from both mods. Hasn't caused me to crash yet and both are useful.

Using the Grim Reaper spell on undead minions cancels out the Undead FX, not sure how to fix, but doesn't affect how they act so not a big problem.

Skull minions do NOT have extended lives under Invested Magic, yet, I'm trying to find out how to get this to work.

Future Changes/Addons: Skull minion/invested magic compatibility.
Possibly including the "Lich Form" mod, should it become more stable in a future update.
