Beast Slayer

For the beast slayer fighting their fellow humanoids is not enough of a challenge, they must seek out and slay the largest creatures they can find. Defeat a rival tribe’s greatest warrior? Yawn. Bring down a rampaging reptile that towers over the jungle like a mountain? Now you’re talking.

Trophies

Beginning at 3rd level, when you slay an aberration, beast, dragon, fey, monstrosity, or plant that has a CR at equal to or greater than your levels in barbarian, you may harvest a trophy from it. Harvesting a trophy involves a 10-minute ritual. The type of trophy you take determines the benefits the trophy grants as long as you carry it on your person. You may only have a number of trophies equal to your proficiency bonus at one time, and may harvest a new trophy to replace one you already have, losing the benefits of the replaced trophy. Trophies lose their power when you are no longer using them. You may not have more than one type of trophy at a time.

Bones

You drape a necklace of bones around your neck, adorn your armor with ribs, mount a skull upon your shield, or otherwise display the bones of the creature you have slain. While raging, you gain resistance to necrotic damage. Additionally, you have advantage on death saves while you have this trophy.

Fangs/Claws/Talons

You don gauntlets with sharp talons over your forearms, a necklace of fangs, helmet made of tusks, or otherwise display the biting and clawing instruments of your prey. While raging, as a bonus action you may make an unarmed attack inflicting 1d8 piercing or slashing damage (depends on the nature of the trophy). This bonus damage increases to 2d8 at 10th level, and 3d8 at 15th level. Additionally, you have advantage on Strength (Athletics) checks to climb.

Feathers

You drape over your shoulders a cloak made of bright feathers, a headdress sporting a crown of feathers, armbands of trailing feathers, or some other display of your trophy. While raging, you may take the Disengage action as a bonus action. Additionally, you have advantage on Wisdom (Perception) checks.

Head

You mount the preserved head of a creature on a spike you carry, attach it to your shield, wear it as a helmet, or otherwise display the grisly trophy. When raging, other creatures may not gain advantage on attacks against you. Additionally, you have advantage on Intelligence (Nature) checks.

Horns

Your helmet is adorned with spreading antlers; you place a pair of horns on your shield, wear a breastplate of interlinked antlers, or otherwise display your trophy. When raging, you may use a bonus action to take the Dash action to spring into the air, allowing you to move vertically up to your full speed. Additionally, you have advantage on Wisdom (Survival) checks.

Furs

You don a cloak of fur, fur armbands, fur hat, or otherwise display your trophy. While raging you gain resistance to cold damage. Additionally, you gain advantage on Dexterity (Acrobatics) checks.

Scales/Skin

You don a cape made of a scales, cover your shield in thick hide, craft a shirt adorned with strips of thick leather, or otherwise display your trophy. While raging add your proficiency bonus to your AC. Additionally, you have advantage on Wisdom (Animal Handling) saves.

Heart of the Beast

Starting at 6th level, when you harvest a trophy you may also, during the same ritual, eat the heart of the creature you have slain. If the creature does not have a heart you eat some other vital organ. When you do so you gain the effects of a short rest. You may do this once, and regain uses following a long rest.

Fatal Blow

At 10th level you gain the ability to aim your attacks against creatures larger than you at their most vital points. When you succeed at an attack roll against a creature larger than you, you inflict an additional 1d8 points of damage. This bonus damage increases to 2d8 at 15th level.

Bloody Rage

Beginning at 14th level, while raging you may, as an action, use your heart of the beast feature.
