Another Greatsword?

[Soilwyr]

So I sold the greatsword from Trevo Mine, while I didn't have the "Vocation Frustration" quest and it seems, you can't buy back items.
Does someone know where to find another greatsword? I found the Lifetaker, but when I give it for the quest, I get the normal greatsword.

Greatswords and Archistaves are sold in Checkpoint Rest Town. You can take an ox cart there from Vernworth.

Thank you! :)

Hope this works for me because I too cleared out the cave before getting the vocation quest..

In my case i can't find someone who actually sells it ...
