Just wondering what the best locations were for higher q stone, and if there was any way to tell the quality besides taking a stone from every single rock you come across, as this become rather tedious.
So you have to walk around digging on a mountain? I've been trying that for ages, I tried climbing higher, I tried all over the place and all I found was q10.
Your best bet is caves, otherwise yes, just like all the other nodes out there you need to keep testing areas by chipping away until you find a decent node.
