In-game description: Experience and training grant you bonus stats while wearing any armor.
In-game effect description: Advancing this skill increases bonus granted to stats.
Armor Mastery increases the defense of all protective gear items by 2% per skill level. The skill increases by at least 1 point per item, which makes the first level more effective compared to the next few levels. Generally, this skill is not considered to be worth the skill points, due to the fact that it does not stack with any of the advanced armor skills.
