Can I earn Buff points if I complete in-game challenges in Valorant?

Buff rewards you passively with every game you play, so you'll slowly be heading to that gift card, but if you want to get there faster, you'll need to do Buff's challenges in the app and claim the Buffs once you've completed them. Doing in-game challenges won't give you any extra points on completion, so if you're keen on some gift cards quickly - focus on those challenges in the app!
