Bloodletters are the daemonic soldiers of the Chaos God Khorne. These red-skinned fiends march to battle in orderly formations, which quickly fall apart once the battle is joined and their bloodlust is up. Crimson Killers. In many ways, a bloodletter resembles an archetypal fiend. It is a humanoid daemon with scaly red skin, goatlike legs ending in cloven hooves, spikes growing from their spine and shoulders, and a large, conical skull with two backswept antlers.
