Traits

Distracting Beauty

A creature that starts its turn in the lymarien swarm’s space must succeed on a DC 15 Wisdom saving throw or be distracted by the swarm’s luminous eyes and fluttering wings until the end of its next turn. A distracted creature has disadvantage on Wisdom (Perception) checks and on attack rolls against the lymarien swarm.

Innate Spellcasting

The lymarien swarm’s innate spellcasting ability is Charisma (spell save DC 13). It can innately cast the following spells, requiring no material components:
At will: dancing lights, minor illusion
3/day each: hypnotic pattern, sleep (affects 9d8 hp)

Speak with Beasts

The lymarien swarm can communicate with beasts as if they shared a language.

Swarm

The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a Tiny lymarien. The swarm can’t regain hp or gain temporary hp.

Actions

Claws

+7 to hit. Hit: 6d6 slashing damage.

Melee Weapon Attack: +7 to hit, reach 0 ft., one creature in the swarm's space. Hit: 21 (6d6) slashing damage, or 10 (3d6) slashing damage if the swarm has half its hp or fewer.

Flight of the Fey

Recharge 4–6

The lymarien swarm lifts a Large or smaller creature in its space. The target must succeed on a DC 15 Dexterity saving throw or be lifted directly upward to a height up to the swarm's flying speed. When the swarm moves, the lifted creature moves with it. At the end of the swarm's turn, the swarm drops the creature, which takes falling damage as normal.
