How can I exchange gold medals for a rainbow? I need a spirit numen of fire borna's gem to evelve one of my monsters. It is available in monster exchange for 3 rainbow medals. I got one rainbow medal from a special dungeon for players with P&D pass but I have been playing Ganeshas treasure trove multiple times to get gold silver and bronze medals. In monster exchange you can exchange multiple bronze for silver, multiple silver for gold but no way to exchange multi gold for rainbow medal. I also have multiple silver draconic orchestra tickets that can't be spent on anything.
