Player's Handbook · Chapter 14

Gas

"Gas! GAS! Quick, boys!—An ecstasy of fumbling Fitting the clumsy helmets just in time, But someone still was yelling out and stumbling And flound'ring like a man in fire or lime.— Dim through the misty panes and thick green light, As under a green sea, I saw him drowning." — Dulce et Decorum Est, Wilfred Owen

The foul putrescence of SLAGG vaporized with the essence of fading living matter. Toxic to those who cling to life — even more so to those who deny their own existence.

But not all drown.

Being Gassed

Test Toughness DR14 each round GAS is present to avoid succumbing. On a failed test, all caught within its wrath without a gas mask are permanently disfigured according to the table below.

Gas Masks

The salvation of a gas mask (<@gas-mask.equipment>) prevents the smothering torture; there is a 1-in-4 chance the mask breaks. If you avoid the damage, suffer SHOCK.
