Path of the Madman

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 Madness

Starting at 3rd level, you emanate a stormy, magical aura while you rage. The aura extends 10 feet from you in every direction, but not through total cover.

Your aura 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 aura’s effect depends on that chosen environment, as detailed below. You can change your environment choice whenever you gain a level in this class.

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

When this effect is activated, all other creatures in your aura must make a CON saving throw as a drunken stupor attempts to take hold of each of them. On a failed save, all affected creatures become intoxicated, gaining disadvantage on all attack rolls. Affected creatures may make a CON save at disadvantage at the end of their turn to break the effect of the aura.

Mad Soul

At 6th level, the storm grants you benefits even when your aura isn’t active. The benefits are based on the environment you chose for your Storm Aura.

You gain resistance to poison damage, and you have advantage on CON saves when drinking alcohol to avoid becoming intoxicated. Moreover, as an action, you can make any one weapon you are touching become a poisoned weapon, dealing 1d4 poison damage on a hit. This effect lasts for 1 minute before dissipating.

Shielding Fury

At 10th level, you learn to use your mastery of the storm to protect others. Each creature of your choice has the damage resistance you gained from the Storm Soul feature while the creature is in your Storm Aura.

Raging Frenzy

At 14th level, the power of the storm you channel grows mightier, lashing out at your foes. The effect is based on the environment you chose for your Storm Aura.

When a creature within your aura hits you with an attack, you may use your reaction to force them to make a CON saving throw. On a failed save, the target is engulfed in purple flames and takes fire damage equal to half your barbarian level.
