And how to get high level stuff for crafting?
I have arkeologi and underworld trading but only get level 6 items when i need a level 7 for Rakata gear.
The rakata crafted gear only requires a Biometric Crystal Alloy. Those are obtained through HM FPs (the last boss drops them). But they are very common now. Last time I checked they sell for about 3k on the GTM.
