"Yesterday, we took a look at some of the new items in patch 2.3 that will be in the crosshairs of farmers across the servers. Today we'll finish off that list.  First, blacksmiths will want to keep their eyes out for the new craftable weapon chain being added to the game. While the source of the Adamantite Weapon Chain is currently unknown, it is speculated to be an Outland-wide world drop. If this is true, then the plans will have a low chance to drop from any creature in Outland. Hopefully this will prove not to be the case and it will be discovered on a specific creature's loot table, since the only other weapon chain is a world drop thus and notoriously difficult to obtain.Fishing gets a boost in the patch through the new ability to track fish schools. This new skill is attainable by reeling in a crate from one of the pools of fish currently in the game. If you find a Weather-Beaten Journal when you crack open the box, you'll be able to click on it to learn the new ability. If you'd like to make a little extra cash, leave the book in the box and sell it via the trade channel. Currently on the PTR, the book is BoP, but its container is not.  Finally, a new non-combat pet can be found back in good old Azshara. This largely deserted zone was once a farmers' paradise and it will probably see more action in the weeks following the patch than it has in quite a long time. If you read Amanda's article the other day, then you'll know that the Azure Whelpling will be the source of all the new hubbub in the old area. The new pet reportedly drops from any of the blue dragonkin that are found on the southern peninsula of the zone.  Hopefully this list will be helpful in knowing which areas to visit or avoid when the patch comes out. It's complete and up to date, to the best of my knowledge. Please post a comment below if I've left something out and we can make this a nice reference tool. I'm sure I'll be looking over it again myself on patch day."^^<http://www.w3.org/2001/XMLSchema#string>
