Greetings fellow crafter! I need some help

I've been trying to craft by myself some Drachen armor Augmentation for my DRG.

I've done the quest in mhordona, and bought with 5x demimateria ( filedcraft/ battlecraft) the master recipe for my Alchemist

The problem is that the Book give me only 16 WEAPONS recipe and not 1 single aumentation item for armors.

Where can i get the Augmentation Armor items? Thanks for the help
