I just can't seem to pull large scales and I'm only 2 away from finishing my twf dual mineral 2s. Been that way for more than week of constant shroud runs now. I'm willing to trade you choice of any 2 bones, shrapnel, or arrowheads for each Large Scale you have.
I'll give 5 of them for 2 Large Scales for the convenience of one trade
Can also work out a deal if you need a bunch of smalls/mediums for your crafting. Got a whole truckload of those.
