The Blood God gifts his most dedicated slaughterers with mutations that better enable them to kill in his name. A Bloodspawn is especially 'blessed' in this manner, having become horribly swollen and distorted with Khorne's murderous power. Huge, bulging muscles, razor-sharp bone spurs, vicious talons, and more are the hallmarks of a Bloodspawn. When one is herded onto a pitch and unleashed in all its destructive glory, the ensuing carnage can turn the stomach of even the most bloodthirsty fans.
The Bloodspawn will inevitably dominate any area of the pitch, either through the application of extreme violence or the intimidation factor of its murderous capabilities. If you want a player to deal with other Big Guys or smash a cage with impunity, waste no time in adding the spectacularly brutal Bloodspawn to your Khorne team's roster.
