Consume Vigor (Ex)
Replaces: Uncanny Dodge
At 2nd level, when a raging cannibal reduces a creature of the same creature type as herself to 0 or fewer hit points with her bite attack while raging, she can consume a chunk of its body to gain a portion of its power. When this occurs, the raging cannibal gains 1 additional round of rage, provided the creature’s Hit Dice equal or exceed her barbarian level. At 5th level and every 3 levels thereafter, the raging cannibal gains 1 additional round of rage each time this ability is used. This ability replaces uncanny dodge.
