As I'm getting close, I noticed the reward for getting all 20 of your equipment to lvl 7 (which takes Medium Refine runes) is.......Medium Refine Runes. LOL. The only problem is when you get all of your equipment to lvl 7, you have no need for Medium Refine runes anymore, you have to start using Advanced Refine runes. So the reward is bunk :P.
