There's already a Dragon Gatherer's cog.. why add quarrying to the lairshaping one? I was talking to Knosses on Istaria and he agreed that it really isn't necessary. Quarrying doesn't have to do much with lairshaping technically. It's bugging me that I can't stack it in with other crystals in my claw because of the conflicting quarrying skills.
If there has to be 3 skills applied to the crystal, add focus to it as well as Knosses mentioned. I believe it helps up lairshaping skill, does it not?
But yeah, that was just bugging me. Random suggestion.
