Depending on your status , eg being fully elite or not , you will need to use promerium for your engines , lasers , shields or rockets if you like to hunt other companies , yes when you are just a beginner , sell it and make credits but when u become more advanced 'promming up' as they call it can sometimes be essential to get away from enemy ships , it increases your firepower by 30% ,
Increases firepower (+30%) or output (+20%)
