Path Of The Performer

For this path of barbarian the barbarian in question has channeled their rage not to one individual, but to society as a whole, maybe they've had yet to find their big break or have been sabotaged by a rival. Whatever the case is this barbarian has channeled their rage into over the top theatrics and is willing to send a message to anyone willing to rumble.
