When you are wearing heavy armor, lessen the armor check penalty of the armor by 2 and increase the armor bonus by 1. Both of these effects stack with the benefit of the Heavy Armor Optimization feat, for a total lessening of the armor check penalty by 3 and a total increase to the armor bonus of 2.
A fighter may select Greater Heavy Armor Optimization as one of her fi ghter bonus feats (see page 38 of the Player's Handbook).
