Commentary:

This skill increases the defense value of your armor, increasing your durability, and also decreases the requirements (e.g., lowers the level, strength, dex, etc. requirements) of a piece of armor. This skill can be useful as a default (e.g., those times when you go "I don't know what to do with my skill points") skill. Everyone probably should aim on maxxing this skill out.
