Armor Breaker

Overview
Armor Breaker is an unlockable starting card for the Knight class. It is a rather situational card, but is very effective when played right. The best way to use this card is to use other cards in conjunction which will grant bonus strikes, so that the armor breakage will be maximum. Even a moderate amount of armor breakage is quite useful since the card stays in effect for multiple rounds. Remember to play all the cards which grant extra strikes before playing Armor Breaker, since it only considers the strikes you have already gained for the armor breakage effect.

This card is upgradeable and increases the number of rounds for which the armor breakage persists.

Armor Breaker cannot be found during runs by any class, but can be passed to other classes by Knights after death.
