It would be really awesome if you were able to convert X number of basic and medium refines into medium or advanced refines. If you went with the same ratio as in lucky board it would be 6 basic refines equal 2 advanced and 3 medium equal 2 advanced refines. This would be a great addition to the game because many player have lots of unusable basic and medium refines that could be put towards this system. This system c*so be used for the basic and medium threads that many people have no use for either.
