  • Hold Breath. The selkie can hold its breath for 30 minutes.
  • Innate Spellcasting. The selkie’s innate spellcasting ability is Charisma (spell save DC 13, +5 to spell attacks). It can innately cast the following spells, requiring no material components:
  • Magic Resistance. The selkie has advantage on saving throws against spells and other magical effects.
  • Shapechange. The selkie can use its action to polymorph into a seal, or back into its true form of a fey creature. Its statistics, other than those for the Hold Breath feature, are the same in each form. They shed their seal skins after transforming. The selkie reverts to its true form if it dies.
  • Speak with Beasts. The selkie can communicate with beasts as if they shared a language.


  • Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (1d8 + 2) piercing damage.
  • Unarmed Strike. Melee Weapon Attack: +4 to hit, reach 5 ft. one target. Hit: 5 (1d6 + 2) bludgeoning damage.


Sailors swear that some seals can turn into humans. This is close to the truth, selkies are actually fey creatures that can shapechange into seals.

Rocky Romance. Selkies have been known to fall in love with humans who find their seal skin. If someone possesses their skin, the selkie’s magic doesn’t work on them. The fey aren’t the best judge of character and find it hard to escape unhealthy relationships.

Children born from marriages with selkies have webbed toes and fingers.

Seven Year Hitch. Every seven years there is a chance a selkie can’t return to its humanoid form and remains in seal form. These shapechangers are usually shunned by other fey creatures and forgotten about.
