Path of the Fiend Hunter

The fiend hunter is one who focuses on the hunting and eradication of fiends, whether it be a personal vendetta, or a righteous cause.

Hatred of Evil

Starting when you choose this path at 3rd level, when you enter a rage within 30 feet of one or more evil aligned creatures, you gain 1d12 temporary hit points for each. In addition, you have advantage on Intelligence (Arcana and History) checks to recall information about fiends.

Experienced Slayer

Beginning at 6th level, you become an expert at spotting weaknesses in your enemies defenses, especially when it comes to the denizens of the Nine Hells, and can add your Intelligence modifier to your melee weapon attacks, as well as having advantage on attack rolls against fiends.

Unending Rage

Beginning at 10th level, if your rage would end, you may instead move up to half your movement towards a hostile creature you can see, and make a melee weapon attack against that target with advantage. Your rage now lasts for 1 minute longer.

Once you use this feature, you can't use it again until you finish a short or long rest.

Hunter of the Planes

Starting at 14th level, whenever you hit a creature with a melee weapon attack, you can mark the creature. If the attack was a critical hit and the target was a fiend, you may immediately banish it to its home plane after applying the following effects. For the next hour, if the creature leaves this plane of existence, you know when and where it left from and to what plane it went to and where it is specifically on that plane. If the creature was a fiend, it takes 5d10 psychic damage whenever it moves to a new plane of existence.
