A Silver Stake gas bomb is a unique invention used by the Silver Stake to subdue and capture lycanthropes. The creation was invented by the alchemist Dram Kallen of Baldur's Gate and the bombs are pressurized with a substance to which lycanthropes are allergic (this varies with the type of lycanthrope although typically might be catnip or wolfsbane). When the bomb is thrown against a hard surface, it explodes and scatters the contents over a radius of around 15' (4.8m). The bombs look like small, tightly sealed leather or cloth pouches that faintly radiate abjuration magic. They can cause a severe reaction of coughing and sneezing in a lycanthrope for around a minute, after which the effects begin to subside, but usually remain for the next 24 hours.
