From publisher blurb:
Welcome to VDP's Trio of Subclasses: the Barbarian!
This document includes three Barbarian archetypes, based on the elemental forces of calamity.
Meet the Raging Mountain, earth-wielding strong men who manipulate the ground around them.
The Seething Cyclone, ancient mariners who command the sea and storms to fight for their goals.
and the Flowing Calamity, tropical survivors of their islands fury.
