Path of the Monster

The Barbarians who follow the Path of the Monster Usually never choose it on purpose. Their path was chosen for them the moment they were taken from wherever they used to live and made into a monster. Their backstory doesn't really matter since they cant even recognize the man on the mirorr.

This subclass is one out of many inspired by monsters made by me, this is only a playable version of a boss (The Monster) and due to that it may be unbalanced, any criticism is appreciated.

Wrath of the Monster
