Dungeons & Dragons 5e Element 133 Class Feature: Undead Repellant

You gain the ability to craft a aerosol spray directed at killing the undead. You may craft one spray can each long rest, but may not do so if spending that long rest crafting or repairing any other equipment. You may make a melee attack against undead creatures within a 15 foot cone originating from you. The targets must make a Wisdom saving throw against your Medic Save DC. If the creatures fail their saving throws, they are repelled for 1 minute or until they take any damage.

A repelled 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.
