Energy-absorbing shield
Or better yet, a Level VIII weapon, coupled with such a shield, that channels two types of energy at a time (what kind changable with crystals) into to weapon, with 70% efficency, that adds the energy of shots that hit the shield into your next 10 shots! OH, YEAH! Take THAT, Iocyrm-class Command-ship!
Oh, and make it possible to overload the shield and thus disable the weapon. And another thing, it should be IMPOSSIBLE to reflect antimatter shots.
