You learn to use willpower to induce a state of frenzy:

Berserker's Rage

Action Points: 1 // Willpower Points: 4

You enter a Berserker's rage for 10 turns (60 seconds), while in this state your Strength is increased by 1 per rank in the Berserkers skill set.

While in Berserker mode you are compelled o perform at least one melee attack during your turn, prioritizing that strike before taking any other actions. If you cannot reach an enemy, you must attack the nearest creature, even if it is an ally.

If no valid targets are reachable, you use all your actions points to move toward the nearest creature.

While under a Berserker's Rage, whenever you take damage, you can spend 2 Willpower points to ignore an amount of damage equal to your Strength + level.

While under a Berserker's Rage, your first successful weapon attack each turn returns half its action point cost.

While under a Berserker's Rage, if you would be afflicted with a status or conditions, you can choose spend 2 Willpower and lose Health equal to twice your Strength to remove the conditions or status effect.

While under a Berserker's Rage, you can now use the following action:

Rampage

Action Points: 2 // Willpower Points: 4

You start rampaging, and for this turn and the next one, your maximum Action Points are increased by 2, and the Strength bonus from Berserker's Rage is doubled. However, you can only perform standard melee weapon attacks until Rampage ends. 

When Rampage ends, you become stunned until the end of your next turn. You cannot enter Berserker's Rage until you take a long rest after using Rampage.
