  • Multiattack. The groac’h makes two attacks with its Tusks.
  • Tusks. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (2d4 + 3) piercing damage.
  • Weighted Net. Ranged Weapon Attack: +5 to hit, ranged 20/60 ft., one Small or Medium creature. Hit: The target is restrained until it escapes the net. Any creature can use its action to make a DC 15 Strength check to free itself or another creature in the net, ending the effect on a success. Dealing 15 slashing damage to the net (AC 12) destroys the net and frees the target.
  • Luring Song. The groac’h sings a haunting melody. Creatures of the groac’h’s choice within 60 feet that can hear the song must succeed on a DC 15 Wisdom saving throw or be charmed for 1 minute. The charmed creature regards the groac’h as a trusted friend to be heeded and protected. Although the target isn’t under the groac’h’s control, it takes the groac’h’s requests or actions in the most favorable way it can. Each time the groac’h or its allies do anything harmful to the target, it can repeat the saving throw, ending the effect on itself on a success. Otherwise, the effect lasts 24 hours or until the groac’h is destroyed, is on a different plane of existence than the target, or takes a bonus action to end the effect.
  • Change Shape. The groac’h can use its action to polymorph into a Small or Medium humanoid, or back into its true form. Its statistics, other than its size, are the same in each form. Any equipment it is wearing or carrying isn’t transformed. It reverts to its true form if it dies.


In her true form, the groac’h appears as a richly dressed woman adorned with ornate and enchanting garments that reflect her magical nature. She has long teeth resembling those of a walrus, with warty skin that’s rough like a toad’s hide.

Groac’hs (ho-EKH) are malevolent water-fairies often found inhabiting caverns beneath the sea or coastal areas. They possess the power to change their form and can take on alluring appearances to ensnare their victims. Their ability to shift between shapes makes them formidable predators.

These creatures are known to prey on unsuspecting humans who venture near their domains, using their innate magical abilities to charm and control their victims. Groac’hs are skilled at manipulation and are capable of luring humans into dangerous situations. They have mastery over the forces of nature, particularly water-related spells and abilities. Their underwater lairs are often decorated with treasures pilfered from ships and sailors who fell prey to their charms.

Despite their malevolent tendencies, groac’hs can sometimes be appeased through offerings or flattery. Legends tell of humans who managed to win their favor, obtaining magical objects and cures for ailments. However, such interactions are rare, and most encounters with groac’hs end in tragedy.

Groac’hs are solitary creatures by nature, although some stories hint at the existence of groac’h families. They are sensitive beings, easily offended and quick to retaliate against perceived slights. These creatures exhibit an affinity for spinning and weaving, often engaging in these activities in their lairs.
