Path of the Elemental Rage

Some barbarians take the wild and choatic elements into their forms and channel them to devastating affect. Often taught through tribal rituals or being exposed to the elements in their purest form, these kinds of barbarians are rare but often draw attention due to their unique characteristic of fighting alongside raging torrents and great infernos. Barbarians who follow this path find that one of the elemental planes backs their rage, fueling it with elemental powers.
