Another game, another lucky streak. Omni tev-9 2 systems before St. Ks in a black market station. I killed everything possible to get the money for that. Then got a SN2500 1 system after St. K's and a full set of light ithalium. Plus the standard invicible class.
edit: one more system past where i got the light ithalium is a set of heavy ithalium. much saving involved.
