As @X5 Slicepointed out with the skiller only ironmen/women. The dragon pickaxe is unobtainable for them but I personally do not think they should be able to buy it per se. Maybe instead of adding to the donator store, add it to the MLM store and put a good nugget price on it that way they still can get it but earn it instead. I mean maybe not the best idea but I thought I would at least add my 2 cents.
