Challenges and Achievements

Hello, I'm having fun playing POE2 EA day to day.
As suggested in the preview video for patch 0.1.1, I think the economy will be reset during the EA, but is it possible to leave a proof that you have played in the league up to that point?
It would be better if there were rewards like skins (even a reprint of the PoE1 challenge skin would be fine), but even just a written record would be fine.
Please consider this to keep players motivated.

Sorry for my poor English.
Thank you.
