(this must be done in the order the cards appear in) alright so when you come across the cards equip the weapon foundry the card represents. (crux lomar, Hakke, ect) if you do this on a heroic difficulty it might unlock a special event just like the Black spindel event. it's just a theory but its possible (recommend weapons: Hakke pulse/auto rifle, truth the exotic crux lomar rocket launcher, and a omolon fusion rifle/ sniper)
