Sustained

A weapon with this special weapon property becomes more powerful with each successive round it strikes a target. After hitting an opposing starship, if the sustained weapon hits the same target in the subsequent round, it deals an additional die of damage for that hit. As long as the ship keeps hitting its target, the ship can continue to increase the damage dice for sustained weapons, up to a maximum number of additional dice equal to the number listed by this special property. If this weapon changes targets or misses an attack roll, it loses the bonus damage.
