To Cut A Heart

You are correct in your assumption; I indeed can teach you how to cut a Blood of the Mountain yourself. To do so however requires a set of reagents I do not have access to. This warehouse may be plentiful, but with all the machinations Thaurissan is planning, the good stuff runs dry.

Here, bring me these materials and I will gladly show you the old Dark Iron art of cutting a Blood of the Mountain.

The Dark Iron pride themselves on their mastery over the mountain's body. Seldom has anyone else shown such expertise in manipulating Dark Iron ore and the countless unique gemstones found within its crust.

I appreciate the effort, <name>. This was definitely not an easy task, yet you provided me with such quality materials in no time at all.

Gemstones like the Blood of the Mountain require an extraordinary amount of precision and patience. Just the tiniest bit of unnecessary pressure and the entire jewel cracks in two. Watch closely, for I have only one chance to teach you. You can keep the gemstone once I'm done. See it as thanks for bringing me such a peculiar example of a gem.
