I had hoped to avoid making yet another Miner on my new shard, Siege - but I may have no choice... I can not find any Crystalline Blackrock for sale period, and since it's needed for the highest levels of skill imbuing - I simply need to go get my own... I went to the Yomotsu mines and killed no less than 20 Dull Copper elems which yielded zero Crystalline Blackrock... That's simply too much time invested for too little reward and I won't do that.. So I went and killed a bunch of rats down in the Cavern of the Discarded, again zero Crystalline Blackrock.... This is nuts... So, apparently it's only Miners who don't have to spend more than an hour to maybe get a single Crystalline Blackrock? Right? Or am I missing something? How do you farm the stuff?
