Can anyone tell me what is the purpose of the "Magic Dust" boost?? I can't even give the stuff away!! I think I've actually used about 400-500 to open stuff on the research tree in the 6 months I've been playing, but that's about it. I put 100 dust for 200 planks in the trader...it's still there, 24 hours later...that's like a 6 star trade...no one wants it! Please tell me that at some point it will have value?? Because having to put up 100 scrolls just to get 25 gems is getting old real fast!!
