can someone tell me please where i can find graphite plate ?
in middle sectors loot asteroids,kill cargo ships
Also salvage rank 13-15 upgrade kits to get it sometimes.
Graphite can be found in higher level sectors (Rank 7+) or from cargo ships. If you wish to risk farming cargo ships and getting negative karma, then look for cargo ships being escorted by 3 fighters. One will be using rail guns and the other two will be using ion emitters.
Alternatively you can salvage Rank 13-15 modules/weapons which will yield graphite or osmium + some common components.
Salvage reactor overload r15.
OR abandoned outpost in jericho, wait at the gate to terra and shoot everything that moves.
