I finished the gargoyle contract in Loc Muine but I didn't farm them to get enough gargoyle dust for the Kinslayer outfit. Is there any way to get more dust? I am willing to hack save file if that's what it takes, by any, I mean any. I am playing to PC
The gargoyles stop spawning after you do the contract so you are at loss there. The only other way I know for getting the dust is by doing the quest From a Bygone Era. Where attacking the operator will spawn Gargoyles. But you need to have started the quest in Act II tho.
