Arena is one of the endgame activies in Last Epoch, and is located in Champion’s Gate. If you have an Arena Key or Arena Key of Memory, you can right click it and it’ll open the world map and show the location of Champion’s Gate.
There’s two different modes in Arena: Arena Champions and Endless Arena.
Arena Champions consists of 40 waves with additional rewards that can be chosen, and eventually culminates in fighting an Arena Champion. There are 4 different tiers of Arena Champions with better rewards at higher tiers.
Endless Arena is a mode with unlimited waves that progressively become more and more difficult, and the best Arena runs will be visible in the Leaderboards (opened by pressing L by default). Leaderboards are only available in Online play in a Season. Climb the waves in Endless Arena to show how good you and your builds are!
Characters below level 50 will not be able to benefit from experience bonuses in Endless Arena.
