This is Wuthering Waves' main endgame mode, and it’s comparable toGenshin Impact’s Spiral Abyss.
The Tower of Adversity has a few different modes that you’ll unlock in succession.
You’ll gain access to these at Union Level 27.

Beating a boss will grant you a handful ofAstrite and the boss' respective Echo.
You don’t need to equip an Echo outside of this mode, as these will be reset.
At the end of every run, you’ll encounter a boss.
Completing the Depths of Illusive Realm will net you better rewards as well.
The Depths of Illusive Realm is a temporary mode it’s only around until June 26.
However, like timed events in other gacha games, it’s likely it could make a comeback.
That’s all the information we’ve got on endgame modes in Wuthering Waves!
