Drown

You point your finger at a creature you can see within range. The creature must make a Constitution saving throw. On a failed save, the creature's lungs immediately fill with water and it drops to 0 hit points. The creature can then survive a number of rounds equal to their Constitution modifier before making death saves. If the creature is still under the effects of the spell and is stabilized or receives magical healing, they may make the Constitution saving throw again, ending the effect on a success. On a failure, they once again begin to make death saving throws.
