Tear Gas Grenade (SWAC)

Tear gas, formally known as a lachrymator agent or lachrymator (from the Latin lacrima, meaning "tear"), is a chemical weapon that causes severe eye and respiratory pain, skin irritation, bleeding, and even blindness. Lachrymatory agents are commonly used for riot control. Their use in warfare is prohibited by various international treaties.
Anyone within a Medium Burst Template must make a Vigor roll at -2 (-4 if in an enclosed space). Those who fail are Shaken and remain Shaken while in the gas cloud. Once out of the gas, a victim suffers a -4 to recover from being Shaken for three rounds.
