We've already covered the new Engineering Flying Machines (and what it takes to get them!), but there are also many other new recipes introduced with Patch 2.3. Our very own Insider Trader gave us an overview of profession additions and changes, but I wanted to focus on some of the new recipes that will be available.
First, there is a new weapon enchant in town that drops from the bosses in Zul'aman: Executioner. It ignores 840 of your opponent's armor, which is an increase of 2-5% dps according to the commenters on WoW Head. The proc rate isn't clear yet. There are two movies of it on YouTube. This one showcases the glowy effect and this one shows the weapon in action. It's a 375 enchant and takes 6 Void Crystals, 10 Large Prismatic Shards, 6 Greater Planar Essences, 30 Arcane Dusts and 3 Elixirs of Major Strength.
