Insidious Atmosphere

A Insidious Atmosphere is similar to a corrosive atmosphere, but extreme conditions cause the corrosive effects to defeat any protective measures in 2 to 12 hours.

Description (Specifications)

Insidious (C): An insidious atmosphere is like a corrosive one, but it is so corrosive that it attacks equipment as well. The chief danger in an insidious atmosphere is that the toxic gases will destroy the seals and filters on the character’s protective gear. An insidious atmosphere worms its way past protection after just a few hours on average, although vigilant maintenance or advanced protective gear can prolong survival times.
