You increase the water pressure in pressurize’s area, dealing 2d10 bludgeoning damage to creatures that enter or start their turn in the area; this damage isn’t reduced as a result of being underwater. Succeeding at the saving throw reduces damage by half. A creature that fails its saving throw by 10 or more must immediately attempt a Constitution check to hold its breath as if it had run out of air; if it fails, it becomes unconscious but stable and continues to suffocate normally unless moved out of the area or the spell ends.
