3rd level Way of the Nightstalker feature.
You have enmity with a certain type of creature. Choose one of the following types: aberrations, celestials, constructs, dragons, fey, fiends, shapechangers, or undead. These are creatures of enmity.
You may gain enmity with an additional type every 5th level hereafter (8th, 13th, and 18th). You do not gain additional languages at these levels.
Strike of Enmity
Turn Creatures of Enmity
Starting at 11th you gain the ability to turn creatures of enmity. As an action, you present your holy symbol or item that is a bane to the creature (wolf's bane, cold iron, silver, etc.) and verbally censure the creature of enmity. Each creature of enmity that can see or hear you within 30 feet of you must make a Wisdom saving throw (DC = 8 + your proficiency bonus + your Wisdom modifier). If the creature fails its saving throw, it is turned. This lasts for 1 minute, or until it takes any damage.
A turned creature must spend its turns trying to move as far away from you as it can, and it can’t willingly move to a space within 30 feet of you. It also can’t take reactions. For its action, it can use only the dash action or try to escape from an effect that prevents it from moving. If there’s nowhere to move, the creature can use the dodge action.
At 17th level, when you hit a creature with an unarmed strike you may spend 5 ki points to release your ki to disrupt the creature. The creature must make a Wisdom saving throw against your ki save dc . On a failed save, the target takes 5d6+20 psychic and 5d6+20 force damage or half as much damage on a success. Creatures of enmity have disadvantage on this save. You may only use this feature once per turn.
