I was sitting around 10 hexes or so away. I would pass my turn allowing him to go first, then swoop in, fire 4-5 missles, if I hit in the right spot, 3 would get through. Other times all 4 would get blocked by shields. Then because I passed, I would get to go before him the next round. Fire everything off and retreat. Repeat as necessary. There were enough other corvettes in the area that he was being kept busy with. I didn't see any of them dealing damage, I think they were AI, or at least mostly so. Does the 80% @Xeen Dread was seeing reflect the dodge bonus I had? I maxed out Genari Evasion, which is why I think I survived so long. I didn't have extra repairs specifically because I figured it was a waste of LP when I could be taken out in one round of focused fire.
