Silver Stake gas bombs

A Silver Stake gas bomb was a unique invention used by the Silver Stake to subdue and capture lycanthropes.

History
It was invented by the alchemist Dram Kallen of Baldur's Gate.

Description
The bombs looked like small, tightly sealed leather or cloth pouches that faintly radiated abjuration magic.

Effects
The bombs were pressurized with a substance to which lycanthropes were allergic (this varied with the type of lycanthrope although typically might be catnip or wolfsbane). When the bomb was thrown against a hard surface, it exploded and scattered the contents over a radius of around 15' (4.8 m).

They could cause a severe reaction of coughing and sneezing in a lycanthrope for around a minute, after which the effects begin to subside, but usually remained for the next 24 hours.
