Lose that Item after getting raped by 4 or 5 tough critters, I did, but I found a way to get it back, has only worked once so far for me.
Just as you get ready to go to the nearest Villiage take and spam the pickup button, there is a split second that you are actually alive in the same spot. I know it’s kind of far stretched but this did work for me once, who knows, maybe just a fluke. Let me know if you can get it to work for you.
If all else fails try The MMORPG Exchange L2 Adena . MMORPG-Exchange has supplied me for years and has great customer service and 24/7 instant delivery.
