Wyvern poison

Wyvern poison was the deadly venom extracted from wyverns and commonly used throughout the East Faerûn.

Description
The substance had a telltale bitter scent.

Powers
The deadly poison could be used to coat blades. Once the substance was introduced into a target's wound, it sapped their constitution, by burning through the bloodstream, collapsing veins and arteries, eventually resulting in death as the poison reached the heart. One vial of the poison had enough poison for five applications.
