Hallucinogen

A fighter hit by a weapon with the Gas trait with
this Gaseous Ammo applied must make a
Willpower check in addition to the Toughness
check to resist the effects of being hit by a
weapon with the Gas trait. If this Willpower
check is failed, the fighter immediately becomes
subject to the Insane condition.
Hallucinogen gases contain aggressive psychogenic
chems that attack the subject's mind and make them
doubt their own senses.
