Profession recipe collectors can rest easy as the recipes from Vault of the Incarnates and Aberrus are returning in the form of Overflowing Satchel of Pilfered Recipes, a drop from the early raid boss Igira the Cruel in Amirdrassil, the Dream's Hope.
If you've been unlucky with recipe drops and are reluctant to farm older content or purchase them off the AH, then Patch 10.2 offers another opportunity to collect these valuable recipes. Igira the Cruel, the second boss of Amirdrassil, the Dream's Hope Raid has the Overflowing Satchel of Pilfered Recipes in her loot table that can award profession recipes from previous Dragonflight raids.
The exact quantity of recipes from the satchel and drop chance of the satchel itself remain a mystery. It's also unclear if this satchel is group looted or personal loot. On the plus side since Igira the Cruel is a fairly early boss in the new raid and the Overflowing Satchel of Pilfered Recipes appears on the loot table for all difficulties LFR through Mythic, players should have several chances at obtaining these older recipes.
