btw, I don't know if the rushers bothered... but the geomancer there is one of the best merchants in the game, if you can pass the THREE successive speech checks necessary to keep her non hostile.
she will have at least one, sometimes 2 new legendary items in her shop every levelup. also a good source for rare staffs and robes.
so, there's something for you to do in sacred stone.
a very good reason not to wipe the place out, as well.
