[Fistter]

Hello i have a problem, i had off hand from Toc 25 called Chalice of Benedictus and the problem is, i think i accidently sold it to vendor because its gone from my bag and its too late to buy it back and my question is, can i do something in this situation? I wrote a ticket but im waiting whole day already and there is no response and i dont really know what to do :<

Only items that you bought with coins can be restored.

Sometimes the item does not appear in the buyback tab but you can right click the empty spot and it appears right back. Not sure if it survives a relog though.
