Asparain Adder Venom

Asparain Adder Venom is one of the most lethal substances known in all the Realms. Coming from the small fangs of the Asparain Adder, a small snake. This venom is so powerful a mere drop of it is enough to kill ten men. It kills fast, and victims experience first an odd itching in their throat, then they begin to sweat, and this is followed usually within a few moments their heart swelling in their chest and bursting. Thus the venom's appeal with assassins and others.

The only known cure, or possible cure is Blue Salt. However it has to be given within moments of being exposed to the venom for it to work.
