Concentrated

The first time a weapon with the Toxin trait
with this Toxic Ammo applied hits an enemy
fighter, add 2 to the dice roll to see if it
overcomes the fighter's Toughness. Note that
this Toxic Ammo only affects this weapon's first successful hit, and any subsequent hits, even
during the same action, will be worked out as
normal.
Concentrated toxins are short-lived, but deliver a
strong dose of poison right into the heart of their victim.
