Armor skills
Heavy Armor, Medium Armor, Light Armor, and Unarmored improve armor rating for their respective armor types or when no armor is worn.
How it works
The armor skills increase armor rating from wearing their respective armor types. Unarmored provides bonus armor rating when not wearing armor. The skills level when the character takes physical strikes while wearing the corresponding armor type; the source groups the four skills together and does not provide individual ratings or progression amounts.

The Steam magic guide is a player-authored guide, and the skills page notes that it could use cleanup. Guidance explains the referenced mechanics; it is not a tested damage ranking.
