Renewed Vigor (Ex)
Source: Pathfinder Core Rulebook, p. 33
As a standard action, the barbarian heals 1d8 points of damage + her Constitution modifier. For every four levels the barbarian has attained above 4th, this amount of damage healed increases by 1d8, to a maximum of 5d8 at 20th level. A barbarian must be at least 4th level before selecting this power. This power can be used only once per day and only while raging.
