berserker 'savage frenzy'
Berserkers take the meaning of rage to a new level. Charging into battle with complete disregard for safety, they leave utter destruction in their wake. When going berserk they enter a savage frenzy which turns their blows even more lethal (doubling base damage dealt). However, this savage frenzy is impeded by the use of shield or heavy armor, and so most berserkers simply rush into their fights bare-chested wielding naught but a great axe. Base damage is 2d4 + level. Wielding a shield reduced the bonus damage by 1/3, while heavy armor reduces it again by half the heavy armor penalty. Lack of shield block/wrist shield and heavy armor skills impose half that penalty (up to -30% with none of the skills). Furthermore, tired berserkers only gain a reduced bonus (50%-100% based on current move percentage), and none while fighting defensively.
