You grind for parts (3 for a Descendant, and 1 Code to fully craft, or research as it's called, them) and some minor materials. Then you research each part for like 8-16 hours, then once you have your 3 parts and the Code you research the Descendant for 8-32 hours. It's way less complicated than it sounds and I had every character at the time (except Keelan because he's boring to farm and black) without spending a single cent on the game
