About

The colláis is a large, deer-like creature covered in thick, black fur. A great rack of antlers grows from its thick skull, in which prominent eye sockets display two red embers for eyes. The monster has no mouth; instead, a coarse beard grows in its place.

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.

Summoned Protector. If a forest village is in danger, the villagers might perform a ritual sacrifice to summon a colláis. Once the ritual is complete, the creature appears in the branches of a nearby tree. It then stalks the village and its surroundings. A colláis returns to its home plane after 24 hours.
