Berserk is a daily ability unique to Swordmasters. For 15 turns, the Swordmaster's attack power is doubled, and they recover 30 Life points each turn the effect is active. When the effect expires, the Swordmaster enters a state of fatigue for 50 turns, where their maximum Life and Stamina drop to 1/3, and their movement speed is reduced. It costs 5% of the Swordmaster's Energy to activate.
