Bursting of Water

This spell concentrates the most mystical energies possible to embarrass your energy. As an action, you can use this spell on any humanoid creature within 60 feet that you can see. The creature must make a Wisdom DC 16 save, or they fail. Success means nothing happens. Success means that the creature's bladder is assaulted by magical energies that cause it to fill to the point of bursting. The creature must take the next 5 actions to cleanse their blander. During this time, it is as if they are under stunned condition, and take 1d8 piercing damage at the top of each turn. If the creature's hit points go below 15 due to this, they are knocked prone. If they reach 0 hit points, the creature falls to the ground and starts emitting a foul-smelling odor that acts as the stinking cloud spell in a 5 ft radius.
