Once a character has surpassed the time for which they can hold their breath, they must make a Resilience test every round with a cumulative –10% penalty. On a failed roll, the character automatically starts inhaling the suffocating substance.
|Substance Inhaled||Damage Taken|
|Poison Gas||A character suffers poison exposure. If the gas is also a thick smoke, then 1D6 damage is incurred in addition to the poison’s effect.|
Armour points do not reduce suffocation damage. The damage will only cease once the character can draw breathable air once more. Even then, the character will require a Resilience test to be able to do anything other than wretch or gasp for breath for 1D4 combat rounds.
