So I dinged 48 yesterday and popped up to the fleet to visit the GTN and upgrade my lightsabers (yay!). Wasn't a problem, I had almost 1,000,000 credits saved up.
While I was looking at my gear I reminded myself to look into what an "augment" is (I have one piece of gear I got from the GTN with an augment slot). Tab out, google "SWTOR augments".
Whaaaat?!?? I can buy some doohickeys on the GTN, wander over to a machine and add augment slots to all my gear???
Well, that explains why I had so much coin in my account..... Down to 300k now but sporting fully augmented gear
