Decaying

If a fighter is Injured by a weapon with the
Toxin trait with this Toxic Ammo applied, and
is not taken Out of Action, place a marker on
their Fighter card. For each marker on their
Fighter card, a fighter must subtract 1 from any
Save rolls they are required to make. At the end
of the battle, or if the fighter goes Out of Action, remove these markers from their Fighter card.
Necrotic acids are used to create toxins that can eat
away at armour making victims more vulnerable.
