Horrifying Visage. Each non-undead creature within 60 feet of the Echo Missionary that can see it must succeed on a DC 13 Wisdom saving throw or be frightened for 1 minute. A frightened target can repeat the saving throw at the end of each of its turns, with disadvantage if the Echo Missionary is within line of sight, ending the effect on itself on a success. If a target’s saving throw is successful or the effect ends for it, the target is immune to the Echo Missionary's Horrifying Visage for the next 24 hours.

On a success, a creature takes 10 (3d6) psychic damage.
