The grigs that make up a grig swarm carry tiny, grig-sized fiddles. When the fiddlers play, any non-fey within 30 feet of the instruments must make a successful DC 17 Will save or be affected as though by irresistible dance for as long as the playing continues. The save DC is Charisma-based.
Environment temperate forests
Organization solitary, tangle (2-4 swarms), or cyclone (5-10 swarms)
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 1-1/2 feet tall and weighs about 1 pound.
