Berserk
Hero ability
Berserk. Drinking enough Beer in one turn activates it for a die roll of turns (the current one included): +bonus to every attack, but no Market: you can't buy, sell or play coin cards. More Beer during Berserk doesn't extend it.

Frequently asked questions
How long does Berserk last? What if I keep drinking?
When you drink enough in one turn, Berserk lasts a die roll of turns (the current one included); the game counts them for you. More Beer during Berserk still gives you the Life Points, but doesn't extend it.
