Kirac's Pass question.

I havent played since ritual league. how does the pass work. do i have to buy it each league ?

There is the free pass on top and the paid one in the bottom.
The paid one changes every league and you need to buy it every time a new league comes out if you want those rewars.
But the top ones they just give them as you complete maps with no money spent.

The pass has half of its rewards as free, earned by mapping, generally consisting of 'helpful' game items (extra maps, currency, etc).

The other half is paid for (300 Exilebucks TM), and must be paid for each league. These rewards are all cosmetic, generally split between a unique set and old loot boxes.

You can buy the paid version at any time during the league, and will retroactively get any thing you've already earned. So you can play the league and then buy it at the end after you know you've unlocked the thing you want (useful if you don't know if you'll like the league, or if your play time is unreliable).

All rewards are claimed at your lesiure from the Part 3 town (there's a big long hallway with several vaults that will unlock as you near them if you've accomplished their task).
