Cry of the Forest

The colláis sounds a dreadful and reverberating call. Each creature within 100 feet of the colláis that can hear the cry must succeed on a DC 16 Charisma saving throw or be frightened until the end of its next turn. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the colláis's Cry of the Forest for the next 24 hours. Forest-dwelling beasts and monstrosities with an Intelligence of 4 or lower automatically succeed or fail on this saving throw, the colláis's choice.
