At 3rd level, when you adopt this path, you choose a totem spirit and gain its feature. You must make or acquire a physical totem object—an amulet or similar adornment—that incorporates fur or feathers, claws, teeth, or bones of the totem animal. At your option, you also gain minor physical attributes that are reminiscent of your totem spirit. For example, if you have a bear totem spirit, you might be unusually hairy and thick-skinned, or if your totem is the eagle, your eyes turn bright yellow.
Your totem animal might be an animal related to those listed here but more appropriate to your homeland. For example, you could choose a hawk or vulture in place of an eagle.
Yours is a path that seeks attunement with the natural world, giving you a kinship with beasts. At 3rd level when you adopt this path, you gain the ability to cast the beast sense and speak with animals spells, but only as rituals, as described in chapter 10.
When this effect is activated, each creature of your choice in your aura gains 2 temporary hit points, as icy spirits inure it to suffering. The temporary hit points increase when you reach certain levels in this class, increasing to 3 at 5th level, 4 at 10th level, 5 at 15th level, and 6 at 20th level.
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.
When this effect is activated, all other creatures in your aura take 2 fire damage each. The damage increases when you reach certain levels in this class, increasing to 3 at 5th level, 4 at 10th level, 5 at 15th level, and 6 at 20th level.
The Path of the Totem Warrior is a spiritual journey, as the barbarian accepts a spirit animal as guide, protector, and inspiration. In battle, your totem spirit fills you with supernatural might, adding magical fuel to your barbarian rage.
Most barbarian tribes consider a totem animal to be kin to a particular clan. In such cases, it is unusual for an individual to have more than one totem animal spirit, though exceptions exist.
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.
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.
At 3rd level, you harness your fury to anchor your feet to the ground, becoming a bulwark of strength. While you are raging, you can't be knocked prone or moved along the ground against your will.
