Weapon gizmo shells are used in the Invention skill to generate perks for use on an augmentable weapon. They may be manufactured at an inventor's workbench.
Discovering this device requires level 3 Invention. Success in creating the blueprints earns 400 Invention experience.
Using a weapon gizmo shell opens an interface allowing you to combine different materials to generate perks. This creates a weapon gizmo, which can then be used on an augmented item to give it the perks.
Ancient weapon gizmo shells may also be made at an inventor's workbench, creating Ancient weapon gizmos. These function similarly to the weapon gizmos in adding perks to weapons.
A perk is generated out of materials and placed inside a weapon gizmo shell
