Hi there @KXRC9JMW74 !

We created this leveling event to celebrate the release of elin brawlers! So our rewards focus on elin brawlers, buuuuut it's also open to all brawlers! You'll receive some elin-only 7-day costumes. They're bankable and you can dress any other elins up in it on your account!

I hope this helps :)
