How to unlock any epic skin for FREE in Rivals of Aether II!

EDIT: Now that there are 4 events there are a total of 1000 bucks that can be grinded from events alone. You're still going to get a character to level 40 but now there's a little more leeway.
I was corrected that rarity ranges from common to rare to epic rather than common to uncommon to rare, thanks ‪@DimzIsland‬! I was reminded that Slasher Clairen is indeed an epic skin, making five total. Thanks ‪@Pigyythebest‬ !
Lord forgive me for the clickbaity titles and thumbnail but I'm hoping to start with something small regarding a new feature in 1.1.0 that changes the bucks grind a bit. I'm a bit nervous about uploading my first rivals video but I noticed there aren't a lot of channels that talk about the currency grinding side of the game, and if this one takes off I'll make more videos about earning coins, maximizing bucks earnings, and future-proofing your grind. Until then, scraw you later🐦
