Barbarian (Drunken Brute)

While raging, the drunken brute can drink a potion, or a tankard of ale or similar quantity of alcohol, as a move action that does not provoke attacks of opportunity. A potion has its normal effect, while an alcoholic drink allows the barbarian to maintain her rage that round without expending a round of rage for the day (instead of the alcohol's normal effects). For each alcoholic drink consumed while raging, the barbarian is nauseated for 1 round when her rage expires, in addition to the normal fatigue that follows a rage. Tireless rage does not negate this nauseated condition but the internal fortitude rage power does. This ability replaces fast movement.
