Sleeping Syrup

A creature can apply a dose of this syrup to food or drink with the Use an Object action. A creature that consumes the food or drink must succeed on a Constitution saving throw or gain a level of exhaustion. A creature that fails that saving throw must succeed on another Constitution saving throw after 1 minute has passed or become unconscious for 8 hours. When a creature uses its action to rouse the sleeping creature or the sleeping creature takes damage, the sleeping creature can make another Constitution saving throw, waking up on a success.
