Canith Glider

Flyby. The glider doesn't provoke opportunity attacks when it flies out of an enemy's reach.

Limited Telepathy. Using telepathy, the glider can magically communicate with any other glider  within 60 feet of it.

Magic Resistance. The glider has advantage on saving throws against spells and other magical effects.

Innate Spellcasting. The glider's innate spellcasting ability is Charisma (spell save DC 13). It can innately cast color spray  1/day, requiring no material components.

Assemble. Fifteen gliders can combine to form a Cannith Glider Monster.

Slam. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: 6 (1d8 + 1) bludgeoning damage.

Surprise Landing (Recharge 5–6). The glider emits a psychic pulse at one creature within 10 feet of it. The target must succeed on a DC 11 Wisdom saving throw, or for 1 minute, the target can’t take reactions and must roll a d6 at the start of each of its turns to determine its behavior during the turn:

1–4. The target takes no action or bonus action and uses all of its movement to move in a random direction.

5–6. The target doesn’t move, and the only thing it can do on its turn is make a DC 11 Wisdom saving throw, ending the effect on itself on a success.
