Path of the Abyssal Lord

Some tribes of barbarians worship or are ruled by a powerful demonic entity. These tribes often elect a champion that serves as an embodiment of destruction for the aforementioned demon. A small few of these abandon the tribe and fiend, striking off on their own with a shard of demonic power bound to their soul. These few who reject the evils of the tribe become barbarians of the Path of the Abyssal Lord

Abyssal Strikes

Starting when you choose this path at 3rd level, your weapon strikes carry special demonic power. When you begin a rage, choose one of the following damage types: Fire, Poison, Lightning, or Necrotic. During the rage, your melee weapon attacks deal an extra 1d4 damage of that type.

Inspiring Might

Beginning at 6th level, your allies are strengthened by your fiendish might. While you are raging, every ally within 30 feet of you gains the reckless attack feature.

Fiendish Knowledge

At 10th level, you can cast the spell contact other plane, but only as a ritual.

Undying Destroyer

Starting at 14th level, the shard of fiendish power you carry makes killing you difficult. While you're raging, having 0 hit points doesn't knock you unconscious. You still must make death saving throws, and you suffer the normal effects of taking damage while at 0 hit points. However, if you would die due to failing death saving throws, you don't die until your rage ends, and you die then only if you still have 0 hit points.
