Talk:Armor class: Eagle Warrior/@comment-213.181.52.31-20180108105353/@comment-27198062-20180108235615

Yes the Cataphract does deal a bonus damage of +9 against Eagle Warriors but not because they are in Armor Class: Eagle Warrior but because they are in Armor Class: Infantry, as Cataphracts have a bonus attack against Infantry class but not the Eagle Warrior class specifically.

Like you mentioned, the Jaguar Warrior has a bonus attack against both the Infantry class as well as the Eagle Warrior class. In this case, since Eagle Warriors are in both armor classes the damage is additive, for a total of +10+2=+12 bonus damage. The Eagle Warrior class was given to Eagle Warriors to make them weaker against other infantry, as most other infantry units have a bonus attack against the Eagle Warrior class.

Generally speaking, multiple armor classes are always additive. The system is explained here ff..
