So, #Fortnite have done this thing where they merged all the season passes together to use account-season level gain rather than individual metacurrencies to redeem items.
(previously levels would give you stars to spend on battlepass items, and lego pass stuff would be redeemed with 'studs' earned via quests. Music pass was similar to lego pass, etc
Now it's all just 'you get to redeem X items from Y pass' as you level up, which I don't find as great, but I can understand the slipstreaming)
