Armor Proficiency, Heavy (Combat)
You are skilled at wearing heavy armor.
Benefit: When you wear a type of armor with which you are proficient, the armor check penalty for that armor applies only to Dexterity- and Strength-based skill checks.
Normal: A character who is wearing armor with which he is not proficient applies its armor check penalty to attack rolls and to all skill checks that involve moving.
Endzeitgeist Says: Almost all builds that need this, have it by virtue of their classes. If you find yourself needing this without having access to it anyways, make sure that your class abilities still work in heavy armor!
