Beyond the Stars
Requires Vacc Suit
An insidious atmosphere is like a corrosive one, but it is so potent 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 Traveller’s protective gear. An insidious atmosphere worms its way past protection after 2D hours on average, although vigilant maintenance or advanced protective gear can prolong survival time.
