Frightful Presence

Each creature of the spider's choice that is within 120 ft. of the spider and aware of it must make on a DC 21 Wisdom saving throw or become 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 this feature for the next 24 hours.
