The alpha fish flares its fins in an attempt to frighten its opponents. Each creature within 30 feet that can see the fish must succeed on a DC 13 Wisdom saving throw or be frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, 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 alpha fish's Fin Flare for the next 24 hours.
