Spooky Scary Skeleton

You can use your action to spoop the guts out of others with a soul-chilling gaze, grin, cackle or shriek. When you do so, each creature of your choice within 60 feet of you and aware of you must succeed on a Wisdom saving throw (DC = 8 + your proficiency bonus + your Charisma modifier) or become frightened of you for 1 minute. A creature can repeat the saving throw at the end of each of its turns, with disadvantage if you are within line of sight, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the effects of this feat for the next 24 hours.
