Acidic

A fighter hit by a weapon with the Gas trait with
this Gaseous Ammo applied does not benefit
from armour or Wargear that would normally
increase their Toughness against weapons with
the Gas trait. However, Out of Action results on
the Injury dice generated by hits from a weapon
with the Gas trait with this Gaseous Ammo
applied count as Seriously Injured instead.
Caustic compounds within the gas eat away at filters, making mockery of respirators and hazard suits.
