User blog:Burniez/Anyone know how to get back spheres sold?

There have been lots of new spheres that requires low tier Arena spheres this few updates. Is there anyway to ever get spheres that have been sold a long time ago? Right now I'm technically screwed because I sold Demon Robe away a long time ago and now I cannot make Demolishing Plate..

If anyone know how to get a sphere back that already been sold please tell me.-. I thought they will never get an upgrade.. I was dead wrong.-.
