All demons of Onslaught follow the path of blood and fire. These demons are filled with an incredible rage, and it is only through discipline and control that they can grow in power and progress in rank. The Children of Onslaught flay themselves, removing their own skins as an exercise in extreme willpower. This painful ritual allows them to control and channel the inferno within. Such power deadens the pain, and eventually they can harness the inferno to regenerate their skin and potentially ascend to a greater form. There is only one exception to this path: The Berserkers.
It is not uncommon for the Children of Onslaught to be driven mad by the pain and rage, and in most cases such unfortunates are usually killed by their fellow demons. Very rarely, a crazed follower of Onslaught will survive – the fire and rage growing unchecked. Their lack of control causes their bodies to swell and grow much larger than their brethren. Incapable of focusing enough to regrow their skin they are driven mad, susceptible to uncontrollable berserk rages. In such a state they rampage across the battlefield killing anything that they can.
Berserkers are viewed with a mixture of awe and disgust by the other demons of Onslaught. A perversion of the path. However, when pointed in the right direction, they are undeniably effective.
