Patch 8.3 Visions of N'Zoth goes live January 14th in NA (January 15th in EU). There are no major changes in this new patch. We will basically get higher ilvl version of the 8.2 recipes. There are no new materials for these recipes, they will require ores/herbs from Nazjatar. (the mobs in the new assaults drop 8.2 leathers and cloths)
The last of the Mark 1 Focus produced in Argentina (2008 Version) featured either a 1.6 L Zetec RoCam Flex Fuel engine, a 2.0 L Duratec HE engine, or the 1.8 L Duratorq Diesel Engine. Assembly of the Mark 2 Focus started in 2008 for the 2009 model.
New item level 400 Uncanny Combatant recipes for every profession. Nothing really changed with these, they are like the Notorious Combatant recipes in 8.2 (Nazjatar) but higher ilvl. You can learn the rank 1 from your trainer in Boralus / Zuldazar, but the Ranks 2 and 3 will still require Mark of Honor to purchase.
The tooltip is bugged in the profession window for some of these new recipes. They show the wrong NPC name where you can buy these. They are sold by Jinxy Blastwheel / Bragni. These new NPCs are right next to the old ones: Ozgrom Ragefang in Zuldazar / Leedan Gustaf in Boralus.
You will build a new crafting station called the Void Focus. This is used to craft the new raid gear (ilvl 440/455/470). The new recipes don't directly require materials from dungeons and raids. The Void Focus is like the Abyssal Focus was in Nazjatar (patch 8.2).
The Void Focus is located in the Chamber of Heart. You will get a series of quests to upgrade it. Each upgrade lets you craft a higher level item. Upgrading the Void Focus is permanent. You don't have to upgrade it for each item, you can craft as many as you want once upgraded.
