Head Bowl The depression atop a kappa's head is filled with water. Spilling, evaporating, or otherwise removing all the water from the top of a kappa's head reduces all their Speeds to 5 feet until the basin is again filled with water. A kappa who becomes Prone must succeed at a DC 15 Reflex save or spill their water, and a kappa who becomes Unconscious automatically spills their water.

If a kappa is Grabbed, Restrained, or Stunned, another creature can attempt to spill the water from their bowl by spending a single action, which has the attack and manipulate traits, to attempt an Athletics check against the kappa's Fortitude DC. On a success, the creature spills the kappa's water.

Speed: 15 feet, swim 40 feet

Melee ◆ claw +11 (agile, unarmed), Damage 1d10+3 slashing

Pull Arm ◆ The kappa pulls one of their arms, gaining 10-foot reach with that arm. The opposing arm shrinks to little more than a hand extending from their shell. The kappa can still use their shortened hand to hold things, but they can't use that hand to wield a shield or weapon. By spending a single action to pull their opposing arm, the kappa can return their arms to their original length.
