These small, winged faeries appear to be made out of gray mist, and can conceal themselves completely in the fogbanks and clouds enshrouding their mountainous lairs.

Mist Dancers. These evil and cunning faeries (whose name means “mist dancers” in Old Elvish) overcome their victims by seeping into their lungs and choking them on the bereginyas’s foul essence.

Mountain Spirits. They are most commonly found in the highest mountain ranges, often above the treeline, but they can be encountered in any foggy or misty mountainous region. Shepherds and goatherds often leave bits of milk or cheese to placate them; these offerings are certainly welcome during the spring lambing season.

Actions

Multiattack. The bereginyas makes two claw attacks. If both attacks hit the same target, the target is grappled (escape DC 12) and the bereginyas immediately uses Smother against it as a bonus action.

Claw. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 9 (1d8 + 5) slashing damage.

Smother. If the bereginyas grapples an opponent, it extends a semi-solid gaseous tendril down the target’s throat as a bonus action. The target must make a successful DC 14 Strength saving or it is immediately out of breath and begins suffocating. Suffocation ends if the grapple is broken or if the bereginyas is killed.
