The Dwarven Berserker does not rely on any sort of formal training to defeat his adversaries so much as he does on sheer rage and strength. Berserkers disdain armor, as it only inhibits their mobility when plowing through the ranks of their enemies. They thrive on combat, and even on being outnumbered (which, to them, means more fighting). Dwarves do not look upon Berserkers as war-crazed deviants, rather they are honored as the bravest warriors among other Dwarves.
Like other Dwarves, they are resistant to magical and other effects. Berserkers are seldom impeded by the weakening effects of poisons.
