Expertise in dragonscale crafting is the utmost skill a leathercrafter can
hone. Skill in it is required to get the most out of scales and perfect
the armours crafted from scales. Extremely experienced dragonscale
crafters are able to preserve the primal power inside the scales and pour
it into their work, creating amazing masterpieces. Some of the training
can be achieved by crafting wyvern scales and other suitable scales but
to achieve utter perfection one needs to craft real dragonscales, which
are of course very rare and hard to get.

This skill is a pseudo mastery.
