This venom, extracted from the stinger of a Wyvern, can be applied to any weapon that deals piercing damage to do additional harm to a target.

Upon the first successful piercing attack with a weapon coated in this venom, the target must make a DC 15 Constitution saving throw, taking 4d6 poison damage on a failed save, or half as much damage on a successful one. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralyzed while poisoned in this way.

One vial contains enough venom to coat three arrows or bolts or one piercing weapon (e.g. dagger, rapier, morningstar). Outside of a sealed vial, the venom will be rendered inert after 1 hour.
