Necuratu

I know that.But i'm just asking if it couldn't be added in the profession shops.Since you got kinda all the regeants.Only those are missing.

So i got http://www.db.pandawow.me?item=72006/pattern-bladeshadow-leggings from Dragon Soul.The problem is i can't get Essence of Destruction and Volatile Air from the shops.So it's possible to add those two recipes to shops?
