ive just returned from my lastest damage reduction (dr) tests, this time more technical. each ship has a thing called flag which determines its dr, if we consider only fighting capital ships, theres cruiser corvette capital and supercap. cruiser corvette capital flags dont take any dr watever weap you use, and you can kill it with any weap too. supercap takes about 50% dr from your weaps, and becomes immune to primary once its hp is below 75%. then theres a thing called big damage. basically it mass reduce damage (something like reducing 99% of your proper damage) from primary and non bomb missiles (not including semibomb outlined below) and the dr approaches 100% as the hp of the ship approach 10%, then it become immune. however bombs and semi bombs (infryno piranha emp and trebechet) can kill ships with big damage, but semibombs cant harm ships with supercap once its hp is below 75%. sathanas (which has supercap + big damage) takes exactly 40% dr from your bombs (cyclops helios and rebel bomb) confirmed this time. all beams that cant be fired at a fighter can kill any combination of flags
