Tranquilizer Rounds (10) (5e Equipment)
From D&D Wiki
Any modern firearm which uses bullets for its ammunition can fire tranquilizer rounds. Tranquilizer rounds consist of plastic or rubber bullets which contain a ballistic syringe filled with a potent sedative. In effect, they are a completely unrealistic form of ammunition which can quickly and effectively incapacitate people without causing harmful side effects or injury, like you see in movies and video games.
Tranquilizer rounds change the damage type of a firearm attack from piercing to poison, and inflict -1 points of damage per die. A creature reduced to 0 hit points by an attack using tranquilizer rounds falls unconscious, but is stable and at no risk of dying.
