Elemental Leatherworking

Elemental leatherworking is what I know, and if you're willing to open your mind to the greater powers of substance, I will share with you all there is to learn. Know this, <class>: by choosing this path you agree never to learn dragonscale or tribal leatherworking; there is only room for practice of one of the three arts. Furthermore, I'll need adequate proof that you are in tune with the elements of nature; to that end, bring me the purest essences of fire, water, earth, and wind.
