Dark Lord:
That's the basic chassis. I think fear and awe as a baseline is pretty powerful, but he's pretty expensive, and demon offers some counters. The magic is pretty limited, and death is not a very useful path for him to have to complement Angmar, so I think the potency of the chassis is ok. Besides, his encumbrance is probably too high to be a very good SC out of the box.
The weapon "Hammer of the Underworld" is currently a magical weapon with ok stats that hits with AoE 1 and turns things slain into soulless. I'm not sure why I have that second effect, but I'm looking for something to make it interesting.
Graphically, I think the legs are too bright inexplicably, so I'll probably play around with that to make it a bit better.
