Seprom is a special type of ore that is used mainly for upgrading any equipped lasers, rockets, and shield generators. Its texture is a purple mineral as shown on the right. Seprom is best obtained by refining another ore called Promerium in the Skylab, at the rate of 189 Seprom per hour (with max modules). It can be much more valuable than Promerium due to it having higher upgrade stats on shield generators (40% increase) or boost the firepower of rockets or lasers (60% increase).
