So I've been looking at the ways to modify gear.
Looks like "enhchanting" is split amoung many many disciplines.
Artifice does weapons enchants, and rumors says some gear?
Synthweaving allows one to make gear and replace parts in other gear, similar to an enchant?
Cybertech, surprisingly makes harnesses and overlays for force users too?
So it looks like chanting gear is split between these three professions...
Or alternatively for nonforce users you need Armormech, Armstech and Cybertech.
