This scabbard, sized for a short sword, has a reservoir in which poisons can be stored. When a blade is placed in the scabbard and then drawn, the venom is automatically and magically drawn from the reservoir to coat the blade. The venom is wiped from the blade after one successful hit on a target, or it evaporates after 2d4 rounds. Any venom can be used, for the dweomer gives the venom virulence against whatever creature is struck. The scabbard holds enough poison for six doses, but must be manually refilled when empty. All other restrictions which normally apply to the use of poison weapons apply here.
