When I try to make the Bloody Tooth Pitfighter's Mercenary Coat, it does not recognize my Shadeweave Root. Actually, looking through other Bloody Tooth Merc recipes, several do not see the rares I have. I did make a bug here: [EQII-777] Bloody Tooth Pitfighter's Mercenary Coat recipe does not see Shadeweave Root - Daybreak Community Issue Tracker
The Bloody Tooth Pitfighter's set of 4 is labeled as wanting shadeweave, but really wants the shadowstone ore. (Ore makes more sense anyway, since it is plate armor, but ...). I filed a /bug a couple days ago about it.
