Sara. The Kappa has a natural divot in the top of it's skull, which must remain filled with water when the Kappa is on land. Because of this, the Kappa has disadvantage on all dexterity saving throws when outside of water

If the Kappa loses the water in it's Sara, it immediately becomes Paralyzed.

If it remains in this state for more than one hour, it becomes Petrified until freed by the greater restoration spell or other magic.

Restoring water to the Sara will render the Kappa loyal, although the water must be from the Kappa's home lake or river.

Honor-bound. The Kappa is incapable of willingly lying or breaking a promise.


Multiattack The Kappa makes two Claw attacks, or one Grapple and one Claw attack

Claw. Melee Attack: +4 to hit, reach 5ft., one target. Hit 5 (1d6 + 2)

Grapple Melee Attack +4 to hit, reach 5ft., one target. Hit 5 (1d6 + 2) and the target is Grappled (save DC 12)

Bard's Notes

  • Seems to be intelligent, and fairly harmless, if mischevous. That said, especially cruel or aggressive Kappa can become a risk to children and livestock -- even full grown adults, on occasion.

  • Surprisingly polite, and unwilling (unable?) to break their word, despite their seemingly capricious nature.

  • Particularly enjoy cucumbers.
