Special Traits

  • Keen Smell. The selkolla has advantage on Wisdom (Perception) checks that rely on smell.
  • Shapechanger. The selkolla can use its action to polymorph into a humanoid or into a seal, or back into its true form, which is seal-humanoid hybrid. Its statistics, other than its AC, 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.
  • Telepathic Bond. The selkolla ignores the range restriction on its telepathy when communicating with a creature it has charmed. The two don’t even need to be on the same plane of existence.


  • Multiattack (Humanoid or Hybrid Form Only). The selkolla makes two attacks: two with its eye poke or one with its eye poke and one with its bite (hybrid form).
  • Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 5 (1d4 + 3) piercing damage.
  • Eye Poke (Humanoid or Hybrid Form Only). Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 6 (1d6 + 3) piercing damage, and if the creature can see the selkolla, it must make a DC 15 Dexterity saving throw. If the saving throw fails by 5 or more, the creature loses one eye. If the creature has just one eye remaining, it has disadvantage on Wisdom (Perception) checks and ranged attack rolls. If it has no eyes remaining, it is permanently blind. Permanent blindness lasts until the creature’s sight is restored by the lesser restoration spell or other magic. Otherwise, a creature that fails the save begins is temporarily blinded in one eye until the end of its turn. The blinded creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. Unless surprised, a creature can avert its eyes to avoid the saving throw at the start of its turn. If the creature does so, it can’t see the selkolla until the start of its next turn, when it can avert its eyes again.
  • Charm. One humanoid the selkolla can see within 30 feet of it must succeed on a DC 15 Wisdom saving throw or be magically charmed for 1 day. The charmed target obeys the selkolla’s verbal or telepathic commands. If the target suffers any harm or receives a suicidal command, it can repeat the saving throw, ending the effect on a success. If the target successfully saves against the effect, or if the effect on it ends, the target is immune to this selkolla’s Charm for the next 24 hours. The selkolla can have only one target charmed at a time. If it charms another, the effect on the previous target ends.
  • Draining Kiss (Humanoid Form Only). The selkolla kisses a creature charmed by it or a willing creature. The target must make a DC 15 Constitution saving throw against this magic, taking 32 (5d10 + 5) psychic damage on a failed save, or half as much damage on a successful one. The target’s hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0.
  • Etherealness. The selkolla magically enters the Ethereal Plane from the Material Plane, or vice versa.


This seal-headed horror walks the streets naked, heedless of the looks it’s getting.

Selkollas are terrifying beings formed from the dead children of neglected parents. When those parents fail to ensure the health of a baby by ignoring its needs, its soul it claimed by a selkolla, who returns as an adult seal-headed creature hell-bent on making everyone pay for their sins.

Children Avenged. Selkolla seek out parents of children who cheat on their spouses and then appear as attractive humanoids to tempt them into bed. Once here, the selkolla transforms into its hybrid form. Those who dare to defend its chosen victim are often found with their eyes gouged out.
