Sell prime parts at the kiosk in any relay. Super fast way to clear your vault. The rarer the part, the more ducats you get. Gold parts give the most.
Use void relics to farm prime parts first. Crack a few and cash in.
Baro uses ducats for his stuff, so hoard them before he shows.
Always keep some parts just for ducat dumps. Don’t sell everything.
It’s one of the easier currencies to farm tbh. Kinda chill.
Pair it with void traces and you’re set for events too.
