Thanks for tip. I farmed that for a long while before the patch. Wasnt that one supposed to be from a thieves trove?
Yes I spent many hours riding around looking for troves that were already looted.
Yes, I kept trying to find Troves, too, and had no luck. Or if I did, there was no lead in them. And then it just dropped randomly off a chest. Makes me much happier than having to chase Thieves Troves...
It also drops from the random Daedric events that spawn around the zone. Got mine from one of those.
So it seems like the Sap-Stone Lead has different sources, not just Thieves Troves. Yay
