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 is near Death's Door, the foul-tempered bagiennik applies healing oil to stabilize them, grumbling all the while.
