the different stock levels are confusing, care to explain how it works? it says 1 for 1 but the stock levels says differently
In general, it's 1:1. If however, we are really low on runes (runes that are red), then we ask for 2:1 instead. If you are trying to give us runes we have a lot of (runes that are green) again, we ask that you give twice the amount. The idea is to encourage rune diversity, which… hasn't always happened, thus we have 800 fire blasts in the pool and people taking out other commons. The rules are there to try to promote diversity and fairness for *all* of the players =).
But anything, white to white, green to green, blue to blue, is all 1:1. And if you trade anything in that is red or white, you can almost get any other rune 1:1.
