Drip Of Hemlock

You touch a piece of prepared food no larger than 1 lb. in size or a container holding 4 pints or less than liquid, contaminating it with a incredibly potent poison. Any time a creature that eats or drinks the poisoned food or liquid before the end of the spell, it must make a Constitution saving throw. Creatures immune to poison automatically succeed on the saving throw. On a failed save the target takes 10d10 poison damage and is poisoned for 12 hours. If this damage reduces the target to 0 hit points, it automatically dies. If the target succeeds on the saving throw it is poisoned for 12 hours. Each hour that the creature stays poisoned it must make another Constitution saving throw, .taking 1d10 poison damage on a failed save, or ending the poisoned condition on a success.
