As a dev pointed out, there is a new NPC in the Loth Vinyards called a "Lothlorien Crafting Guild Emissary." He sells guild-type recipes for many of the Loth-specific teal items, including woodworker weapons. Turbine has also announced new changes for Woodworkers with upcoming Book 8. So we've decided to collect all information about woodworkers and the result is Book 8 Woodworker changes and Lothlorien Crafting Guild Emissary with Gallery.
