This guide provides an overview of the additions and changes to Engineering in World of Warcraft Shadowlands.
Table of Contents
Shadowlands Engineering Trainer Location
You can learn Shadowlands Engineering from Machinist Au'gur in Oribos in the Hall of Shapes. (Coordinates: 38.1, 44.7)
Oribos is the new Shadowlands city hub for both factions. You will arrive there after you finish the Shadowlands intro quests, so you can learn the new profession recipes before you head out questing.
Machinist Au'gur

Acquiring recipes
All new recipes only have one rank, and you can learn most of them from your trainer. This makes leveling professions much easier since you don't have to grind reputations to get higher rank recipes.
These 3 recipes below are the only ones that you can't learn from your trainer:
Schematic: PHA7-YNX - Requires Exalted reputation with The Ascended faction.
Schematic: Wormhole Generator: Shadowlands - Requires Honored reputation with The Undying Army faction.
Recipe: Crafter's Mark II - Requires Cordial "reputation" with Ve'nari.
Materials
The new ores are a bit different from ores in previous expansions because 4 of them are zone specific.
Laestrite Ore - Mined in every zone
Solenium Ore - Mined in Bastion
Oxxein Ore - Mined in Maldraxxus
Phaedrum Ore - Mined in Ardenweald
Sinvyr Ore - Mined in Revendereth
Elethium Ore - Low chance to drop when mining any deposit, or you can mine them from Elethium Deposits (rare spawn).
Porous Stone - Mined from every deposit, except Elethium deposit.
Twilight Bark - Gathered from Phaedrum Deposits in Ardenweald.
You can buy Luminous Flux and
Machinist's Oil from Distributor Au'burk. He also sells a few
Twilight Bark but in limited supply, so he won't always have it.
Immortal Shard for the Belt Attachments is sold by Distributor Au'resh.
Auctioneer accessible only to Engineers
You will find Photonic Gearhaggle the Holographic Auctioneer in Oribos standing near your Engineering trainer. He is accessible only to Engineers, but you don't have to level Engineering, there is no Engineering skill requirement to access this NPC, the only requirement is that you have to have Engineering as a profession.

Optional Reagents
These reagents change the item level of a crafted armor or weapon. (You can actually downgrade an item's item level and its level requirement if you use a lower level optional reagent)
These 3 optional reagents below can only be used to craft items from Shadowlands. All 8 manufacturing professions can craft these, so they are not exclusive to Engineering.
