Hey I wanted to share something interesting I found out.
You can reset your Digsites in Uldum while having ''Mantid Artifact Sonic Locator'' in your inventory just by leaving the zone and coming back in. The end result is you dig your Tol'vir digsites and leave Uldum come back and spawn brand new digsites leading to only getting Tol'vir instead of other races.
I searched if there was a similar post to this but I couldnt find anything so I posted it here.
Have fun farming your Mount or Crawling Claw and GL. Did 50+ solves today so far
PS: Mantid Artifact Sonic Locator can be bought in Vale of eternal blossoms from Brann Bronzebeard. Near the Mogushan palace instance.
