The Warmaster Tomb Kings army I have is an acquisition from a friend who used to play the game. Despite having 1000s of points of Skeleton Warriors he began to paint up some Chaos Marauders as units of ethereal undead warriors. He initially painted them in white but since then GW has released the Hexwraith Flame shade and so I did a wash with that and then drybrushed the models with Pallid Wytchflesh and then white.
