Attribute Proficiency was a feature unique to The Elder Scrolls: Legends Asia. Each of the five Attributes possessed an Attribute Proficiency Level, which could be increased by using cards of that Attribute in your deck while playing.
Players could get new cards as a reward when they level up their Attributes. Players were rewarded for playing different Classes and Attributes to earn experience and new cards, and to learn the best strategies for each Class.
