Brandish Head

You can pull a phantasmal head out of thin air and brandish it for all to see, uttering an ominous threat for good measure. You gain the following benefits.

Ability Score Increase. Increase your Constitution or Charisma score by 1, to a maximum of 20.

Brandish Head. You can use an action to summon a phantasmal head into a free hand. Each creature of your choice within a 60-foot Emanation originating from you makes a Wisdom saving throw (DC 8 plus your Proficiency Bonus and the modifier of the ability increased by this feat). On a failed save, the creature has the Frightened condition for 1 minute. At the end of each of its turns, the Frightened creature repeats the save, ending the effect on itself on a success. On a successful save or when the effect ends for the creature, the creature is immune to Brandish Head for 24 hours.

Special. If you’re already holding a real decapitated head in your hands (by using the Decapitate feat, for example), you can use the real head instead of summoning a new one. If you do, creatures have Disadvantage on their initial saving throw against the effect. After you Brandish Head, the decapitated head you brandished goes up in flames and is destroyed, instantly burning to ash.
