Each ship's armour lists which card suits and ranks cause damage, varying by firing ship class.
How it works
Drawn damage cards are compared to the target ship's armour list against that firer: e.g. Bismarck vs Hood/PoW takes damage from all Spades, all Clubs and Diamonds 5-7, never Hearts. Cards not listed are discarded without effect.
you compare the card to the armor of the target ship. if it is listed on the target ship’s armor then it causes damage.
