According to the encounter journal, new profession recipes have been added to the loot tables of Aberrus, the Shadowed Crucible raid encounters.
In a departure from how profession recipes worked in Vault of Incarnates which appeared to be a shared loot pool of recipes across all the encounters in the raid, Aberrus seems to have certain recipes dropping from specific bosses. This could lead to a much more targeted farm and less dilute loot pool for these unique crafting patterns.
