Special Traits

  • Healing Oil. A bagiennik can automatically stabilize a dying creature by using an action to smear some of its oily secretion on the dying creature’s flesh. A similar application on an already-stable creature or one with 1 or more hit points acts as a potion of healing, restoring 2d4 + 2 hit points. Alternatively, the bagiennik’s secretion can have the effect of a lesser restoration spell. However, any creature receiving a bagiennik’s Healing Oil must make a successful DC 13 Constitution saving throw or be slowed for 1 minute.


  • Multiattack. The bagiennik makes two claw attacks.
  • Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 18 (4d6 + 4) slashing damage.
  • Acid Spray. Ranged Weapon Attack: +6 to hit, range 15 ft., one target. Hit: 14 (2d10 + 3) acid damage. The target must make a successful DC 13 Dexterity saving throw or fall prone in the slick oil, which covers an area 5 feet square. A creature that enters the oily area or ends its turn there must also make the Dexterity saving throw to avoid falling prone. A creature needs to make only one saving throw per 5-foot-square per turn, even if it enters and ends its turn in the area. The slippery effect lasts for 3 rounds.


Bagienniks are small, amphibious fey that hide in tall reeds along rivers. They frequently dig into the silt beneath the pools of hot springs, where they take long naps in the warm and comforting waters and play pranks on foolish bathers who swim too close to the bagienniks’ hiding spots. Despite their capricious nature, the creatures are sought for their healing abilities. They delight in curing maladies and burning away infirmities with their caustic nasal spray.

A local bagiennik is considered a boon in many river towns. Citizens of such settlements often venture to the rivers with offerings, hoping to encourage the fey to stay close and heal their families. A bagiennik that finds a generous town might invite its extended family to settle in, testing the patience and largesse of its hosts.

With webbed claws, bulbous eyes, and two nostril-slits that ooze an oily black substance, the creature is not quite hideous-but it might be, if most of it wasn’t concealed by a thick coating of muck and mud.

Bathing Uglies. When a bagiennik is alone, it spends its time bathing in local springs, rivers, and marshes. The creature sifts through the muck and silt, extracting substances that enhance its oily secretions. If anything disturbs the creature during its languorous bathing sessions, it angrily retaliates. Once a bagiennik has bathed for four hours it seeks a target for mischief or charity.

Unpredictable Moods. One never knows what to expect with a bagiennik. The same creature might aid an injured traveler one day, smear that person with corrosive, acidic oil the next day, and then extend tender care to the burned victim of its own psychotic behavior. If the creature feels beneficent, it heals injured animals or even diseased or injured villagers. If a bagiennik visits a settlement, the ill and infirm approach it cautiously while everyone else hides to avoid provoking its wrath. When a bagiennik leaves its bath in an angry mood, it raves and seeks out animals or humanoids to spray its oil onto. If a victim drops to 0 hit points, the foul-tempered bagiennik applies healing oil to stabilize them, grumbling all the while.

Acid Oils. Collecting a dead bagiennik’s black oils must be done within an hour of the creature’s death. A successful DC 15 Wisdom (Medicine) check yields one vial of acid, or two vials if the result was 20 or higher. A bagiennik can use these chemicals either to heal or to harm, but no alchemist or healer has figured out how to reproduce the healing effects. Other than their acidic effect, the secretions lose all potency within moments of being removed from a bagiennik. A bagiennik weighs 250 lb., plus a coating of 20 to 50 lb. of mud and muck.
