The new Shadowlands Patch 9.2 offers new crafting materials, updated Crafter's Marks, and several new Optional Reagents that you can add to crafted items to make them more interesting and useful.
New profession materials
These can be only gathered in the new zone Zereth Mortis.
Upgrading your Legendary
Legendary items can be upgraded to rank 7 (iLevel 291).
Just like in 9.1, there is no new recipe for the new rank of base items, instead, you can use the new optional reagent Vestige of the Eternal to add 3 ranks to the base legendary item.
You can learn the Vestige of the Eternal recipe from Tome of the Eternal, which is awarded at the end of Chapter 5 during the 9.2 Campaign. (I believe this will be time-gated, so you can only get this 2 weeks after the patch 9.2 launch date)
|Blacksmithing||Vestige of the Eternal||40x Progenium Ore, 15x Shadowghast Ingot, 2x Progenitor Essentia|
|Jewelcrafting||Vestige of the Eternal||2x Essence of Rebirth, 2x Essence of Torment, 2x Essence of Servitude, 2x Essence of Valor, 10x Progenium Ore, 2x Progenitor Essentia|
|Leatherworking||Vestige of the Eternal||40x Protogenic Pelt, 3x Heavy Callous Hide, 2x Progenitor Essentia|
|Tailoring||Vestige of the Eternal||60x Silken Protofiber, 50x Lightless Silk, 25x Penumbra Thread, 2x Progenitor Essentia|
New Crafter's Marks
Crafter's Mark IV changes the Item Level to 233 and the Required Level to 60 of the gear you craft.
Crafter's Mark of the First Ones sets the item level to 262, but it adds "Unique-Equipped: Shadowlands" to the crafted item, so you can only wear one item upgraded with it
You must have Honored reputation with The Enlightened faction to purchase these recipes. Both of them are sold by Vilo.
New optional reagents
There are several new Optional Reagents that you can add to crafted items to make them more interesting and useful.

New profession recipes
There are only a couple of new recipes added in patch 9.2 outside of the new optional reagents.
There is a new healing potion that restores 20,000 health.
You can learn the new potion recipe from your alchemy trainer Elixirist Au'pyr in Oribos.
This feast recipe is different from the previous feasts. Basically, one player places down an Empty Kettle of Stone Soup which becomes an object that other players can interact with. Upon interaction, an interface will pop up and you can donate cooking ingredients to "complete the feast". Each donation contributes 10% and when you fill the bar you can use the feast to get the "Well Fed" food buff.
New Vantus rune recipe Vantus Rune Technique: Sepulcher of the First Ones.
Technique: Glyph of the Spectral Vulpine is from "Night Fae Callings through rewarded bounty and tribute boxes".
