So I'm making a Dread Necromancer starting at lvl 8. I have the build down already, I just need help creating the undead I'm going to start with. I'm limiting myself to CR 6 and below creatures (things I could conceivably kill solo). I've read the handbooks, but what I'm looking for now is specific ideas. So far I have a Zombie 7-headed hydra, a wight, a shadow, a Skeletal Ettin, and a Zombie Nightmare. That's barely over half my control pool, so go nuts!
We have most monster-related books available, with the notable exclusion of Eberron-specific stuff.
