It would be great if people can share any recipes they have found and see if we can make a impromptu database here to help each other out.
Confirmed drop for "Recipe: Theca Leather Armor". I believe this came from Plains of the Lizardmen, but don't remember.

Cruma 3 is now dropping Top C gear. All Full Plate, Theca Leather, Divine Set, Plated Leather Armor.
Please share any spoil recipes from Cruma. Hopefully Full Plate recipes can be found here.
Other lesser traveled zones have recipes scattered. Hunters Valley, Timak Orc, Plains of the Lizardmen. Alligator Island probably has new recipes.
Confirmed drop: Scroll: Enchant Armor (C-grade) - Cruma 3
