From publisher blurb: The force of a barbarian's rage is often described as volcanic, but barbarians following the Path of Roiling Magma truly channel the immense pressures and volcanic forces of the earth into their rages, scouring their foes with heat and unparalleled tectonic forces. Expanding upon the mechanics of the 5E Barbarian class, this PDF allows you to create barbarians who harness the volatile might of volcanoes through their rages. The PDF also contains three volcanic-themed feats suitable for these barbarians or any other character.
