Dark champions of Necropolis.

Horses don't fly anywhere; it would look silly (I checked). The difference is that in one of the versions, both upgrades have the same stats and abilities as they did before the mod.
Oh, I don't even know what to do with this armor; it doesn't look very good in dark colors either... Maybe give it some kind of color tint?
I think there's a piece of texture that was accidentally cut out somewhere. I'll take a look.
