Bring 10 Thick Leather to Pratt McGrubben in Feathermoon Stronghold.
<name>, you're becoming quite skilled as a leatherworker! I know some patterns you might be interested in... Wild Leather armor! Wild Leather taps into the potent and chaotic properties of wildvines, found in areas of lush vegetation and on some of the creatures there. The armor made using it is second to none for people of your skill, guaranteed.
I'll teach this to you, but you'll be working for me for a while. The first cost is simply ten pieces of thick leather. After this, we'll talk specifics.
Like I said, you'll be working for me while you learn about Wild Leather armor. Because wildvines are both potent and chaotic, it yields a random but strong benefit to the already strong armor you will be making. This knowledge, however, was not easy for me to come by.
The initial cost to begin this process is ten pieces of thick leather.
Once that is done, we'll get to the work you need to do in order to obtain the patterns.
Well <name>, I'm glad to have you on board. You've made a smart decision as a leatherworker; those who wear leather armor will be clamoring to you once you learn how to make any of the Wild Leather armor pieces.
Let's get to work - where do you want to start?
