Upgrade Nebula Stones used for a limited time in General Discussion Posted May 15, 2016 · Edited May 15, 2016 by IncredibleOne6 2 hours ago, luzt said: This stone really messed up the market in a bad way. In reality you aint saving much gold, if any, compared to before the Nebula stone. I saved a lot thanks to the events. Saved me a couple gold on the upgrade and 36g for transformation stone. The biggest saving was I didn't have to do dungeons daily for another 5days for enough stingers. So all in all I saved like 40g and 5 days worth of daily stingers. That's a huge saving in my book. All the other mats I have farmed over time doing ssp multiple times a day and kept rather than put on the market.
