UNYIELDING CHITIN

Use this Stratagem in your Charge phase or your opponent’s Shooting phase, when a TYRANID PRIME or TYRANID WARRIORS unit from your army is chosen as the target for an attack made with a ranged weapon. Until the end of that phase, when resolving a ranged attack against that unit, reduce the Damage characteristic of that attack by 1 (to a minimum of 1).
