When a creature that can see Ammon's eyes starts its turn within 30 feet of him, Ammon can force it to make a DC 20 Wisdom saving throw if Ammon isn't incapacitated and can see the creature. On a failure, the creature is frightened for one minute. Unless surprised, a creature can avert its eyes to avoid the saving throw at the start of its turn. If the creature does so, it can't see Ammon until the start of its next turn, when it can avert its eyes again. If the creature looks at Ammon in the meantime, it must immediately attempt the save. While averting its eyes, any attacks on Ammon are done at disadvantage.
