Hello,
I'm trying to figure out what the parameter UpgradeFromItems (inside of an ItemPurchaseRequest) is for.
What I try to achieve is like a typical upgrade where you use 5 basic runes + 100 gold, and you get 1 advanced rune.
I'm using StartPurchase in order to do all in a single transaction with the server, so i can avoid interruptions by losing internet connection and causing an incomplete upgrade.
Any thoughts?
Thank you
