Path of the Demon Soul

There are occasions when a demon is slain and its soul attaches itself to a nearby creature, often a young adolescent but any age is possible. Evidence of this second soul might not appear until later in life but there are subtle destructive urges that the host must fight. Some learn to tame this demon and can call upon it when necessary while others are controlled by it and cannot control when it emerges. In either case these beings are formidable foes.

Abyssal Resilience

When you begin this path at 3rd level your twinning with a demonic soul begins to manifest. You have resistance to poison damage and immunity to the poisoned condition.

 

Intimidation Expertise

Also at 3rd level you gain proficiency in the Intimidation skill and your proficiency bonus is doubled for any intimidation checks.

Path of Slaughter

At 6th level, when you first drop bellow half of you maximum hit points, you enter a berserk state giving you the following benefits.

• Your melee  weapon attacks deal an extra 1d4 damage
• Your movement speed increases by 10ft

This state lasts until you fall unconsious or your rage ends. If you are not raging it lasts for 1 minute.

At 14th level the extra damage becomes 1d6.

Demonic Influence

At 10th level you gain the ability to summon aid from between the planes. You can cast summon greater demon (XGtE) once with no need for material components and a DC of 15. Once you use this feature you can't use it again until you finish a long rest.

Additionally you learn to speak read and write in your choice of abyssal or Infernal

Immortal Anger

At 14th level your rage is so strong that not even death can contain you. If you die, you are resurrected 8 hours later with 1 hit point. If you are disintegrated (as with the disintegrate spell) beheaded, or killed such that your body would not be able to regenerate, this resurrection does not succeed
