Special 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.
  • 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.
  • 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:


  • Claws. 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.

Lymarien Familiars

Some lymarien might choose to serve a good-aligned spellcaster as a familiar. Such lymarien have the following trait.

The lymarien can serve another creature as a familiar, forming a magic, telepathic bond with that willing companion. While the two are bonded, the companion can sense what the lymarien senses as long as they are within 1 mile of each other. While the lymarien is within 10 feet of its companion, the companion shares the lymarien’s Speak with Beasts trait. At any time and for any reason, the lymarien can end its service as a familiar, ending the telepathic bond.
