Paw the Earth

The aatxe lowers its horns and paws at the ground with its hooves. Each creature within 30 feet of the aatxe must succeed on a DC 15 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 aatxe's Paw the Earth for the next 24 hours.
