  • Fiddle. The fossergrim plays its fiddle and chooses one of the following magical effects. Any creature within 60 feet of the fossergrim that can hear the fiddle must succeed on a DC 14 Wisdom saving throw or be affected as described below. Other fossergrims and creature that can’t be charmed are unaffected. An affected creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature’s saving throw is successful or the effect ends for it, the creature is immune to these panpipes for the next 24 hours.

About

This handsome man rises up out of a waterfall, seemingly untouched by its mists, with a fiddle at his side.

Fossergrim are fey who are exceptionally talented fiddlers. They are confined to waterfalls, where they use their music to lure the unwary.

An Appropriate Sacrifice. Legend has it that fossergrim can be convinced to share their talents with bards in exchange for a he-goat thrown with its head turned away into a waterfall that flows northward, or smoked mutton stolen from a neighbor’s storage four Thursdays in a row. If there is not enough meat on the goat or the mutton, the fossergrim merely teaches the bard how to fiddle.
