I got some monster cards and all of them have an information that based on the monster card color if its green you can exchange it for a green currency, if purple than for purple...
Can someone PLEASE explain me how to do it. I tried looking on google and youtube and found nothing... -.-
I noticed some NPCs in Varanas can do it, but I have no idea what to do and who to ask and I can't solo end game instances for materials if thats what's needed... 
EDIT.
I found something, but it's still confusing. Found an information on wiki chronicles of arcadia site...
