Terminus earring SMD. I mentioned that above xD but I didn't wait 8 months without zoning just to keep the boxes prowess, i left after 2 weeks (also 8 hours a day). As far as caskets go, there are several calculators out there that will help you open them, and only with the worst hints or fumbles will you fail in opening the box. Thief helps a little if used before the first hint. It can STILL take upwards of 2-3 days even under optimal conditions (I still don't have a Fisher's Rope despite trying for a week solid under Myriad Mystery Boxes + Boxes 5 prowess). The drop rate is too low, it has nothing to do with people failing at boxes. I got my goldsmithing torque on the very first box without Myriad or box prowess, but that is certainly not the norm. This is essentially the Ebisu Rod Quest Items but in dungeon form; the drop rates are probably around 0.5% considering it takes upwards of 200 boxes (typically) to acquire the item you're after. In some zones, there are no "easy" pages or no "grindable" kills (Sky comes to mind, where the average kill still takes 30 seconds, not the ~1 second a lvl 10 bunny does in Dangruf Wadi). In short, many of these items are unnecessarily difficult to acquire, especially considering the bonuses they provide and the current future of the game. My 2 cents.
