Nearly every patch includes new items for players to farm up. While these additions are typically new tradeskill recipes, occasionally other goodies are thrown into the mix. The upcoming patch 2.3 contains both of these types of items for your farming pleasure (or annoyance). I'll quickly cover the items, where they're dropping and the creatures that drop them in order to create a consolidated resource to help plan your farming once the patch hits the live realms.
First off is the new leatherworking bag. The pattern for the Bag of Many Hides can be found through the mass slaughter of the Gordunni ogres in the Barrier Hills above Aldor Rise in Shattrath. This recipe will allow a leatherworker to create a 24 slot bag to hold the essential tools and materials of their trade.
