Path of The Storm (DI Herald)

All barbarians harbor a fury within. Their rage grants them superior strength, durability, and speed. Barbarians who follow the Path of the Storm Herald learn to transform that rage into a mantle of primal magic, which swirls around them. When in a fury, a barbarian of this path taps into the forces of nature to create powerful magical effects.

Storm heralds are typically elite champions who train alongside druids, rangers, and others sworn to protect nature. Other storm heralds hone their craft in lodges in regions wracked by storms, in the frozen reaches at the world’s end, or deep in the hottest deserts.

Aura of The Storm

Starting at 3rd level, your rage creates an aura of energy around you in the form of a raging storm. 

Your storm has an effect that activates when you enter your rage, and you can activate the effect again on each of your turns as a bonus action. Choose desert, sea, or tundra. Your storms’s effect depends on that choice, as detailed below. You can change your storm type whenever you gain a level in this class.

If your storm's effects require a saving throw, the DC equals 8 + your proficiency bonus + your Constitution modifier.

Desert

When this effect is activated, each creature of your choice in your aura take 4 fire damage. The damage increases when you reach certain levels in this class, increasing to 6 at 5th level, 8 at 10th level, 10 at 15th level, and 12 at 20th level.

Sea

When this effect is activated, you can choose one other creature you can see in your aura. The target must make a Dexterity saving throw. The target takes 1d6 lightning damage on a failed save, or half as much damage on a successful one. The damage increases when you reach certain levels in this class, increasing to 2d6 at 10th level, 3d6 at 15th level, and 4d6 at 20th level. You can add your Constitution modifier to the damage for your aura.
