Special Traits

  • Innate Spellcasting. The swarm of grig’s innate spellcasting ability is Charisma (spell save DC 14, +6 to hit with spell attacks). It can cast the following spells innately, without requiring material components.
  • Surprise Attack. If the swarm of grigs surprises a creature and hits it with an attack during the first round of combat, the target takes an extra 28 (8d6) damage from the attack.
  • Swarm. The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a grig. The swarm can’t regain hit points or gain temporary hit points.

Actions

  • Shortsword. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 12 (3d6 + 2) piercing damage, or 5 (1d6 + 2) piercing damage if the swarm has half its points or fewer.
  • Fiddle (Recharge 5-6). The swarm of grigs begins playing a lively tune with its fiddles. Creatures within 30 feet that can hear the fiddle must make a DC 13 Wisdom saving throw or be charmed for 1 minute. While charmed by the swarm, the target uses its action to dance in place, capering comically. The creature can repeat the saving throw at the end of each of its turns, ending the effect on a success. If the saving throw is successful, or the effect ends for it, the creature is immune to that grig’s Fiddle ability for 24 hours.

About

Winged man-shaped creatures with blue skin and cricket legs buzz about in a dense mass both hypnotic and frightening. A grig swarm is a large mass of flying grigs. Normally grigs don’t gather into groups larger than 80 or so creatures. But sometimes when several tribes come together, they join as a grig swarm. The individual grigs that make up the swarm have light blue skin, forest-green hair, and brown hairy legs, and usually wear tunics or brightly colored vests with buttons made from tiny gems. A grig stands 1½ feet tall and weighs about 1 pound.

A grig swarm normally attacks by surrounding and enveloping its opponents. Before closing to melee range, a swarm uses its entangle ability to bind its foes. If facing destruction, a swarm often turns invisible and flees.
