I fly a Caprimul Class Science Destroyer and I've hit a duranium wall called something like a Vaadwaur Heavy Artillery ship. The mission is Enemies in all the Usual Places > Aid the Kobali Captain > Aftermath.
I have attacked this ship repeatedly, only to be pounded into oblivion by his bleeping tricobalt cluster... uhh... mines. My shields might as well not exist. My neutronium armor might as well be wood, and my Transphasic torpedoes, quantum mines and rapid-fire polaron cannons just bounce off him like rubber. I have attempted both modes of attack - tactical and science and there's really not much difference in the results. Oh, and I forgot to mention the assault ships that materialize out of nowhere. He must be loaded with a hangar bay, too (as if he needed it). I bring my photonic fleet, pirate fleet distress call, quantum torpedo platforms - they help increase my survival time, but I've never brought him below 85% hull.
How do I beat this thing?
