For those Proxies trying to speedrun their way to the top, knowing the max level cap for Zenless Zone Zero is crucial. Not every player is going to farm their way through Commissions in the game to get that extra EXP, but knowing what level you can reach will help you set a goal for yourself.
What happens when you reach level 40? (Zenless Zone Zero)
Thanks to the Achievements screen, we know that the maximum Inter-Knot level for Zenless Zone Zero players is level 60.
There is a gold achievement for reaching that level, and players will receive Polychrome x60 for maxing out their account level. There are also achievements for Level 20 and Level 40.
Your Inter-Knot Level is your account level. Your Proxy – whether you chose Belle or Wise – does not have its own leveling system because they do not enter combat in the traditional manner like the other Agents. So all you need to worry about is leveling up each of your Agents (the companions Belle and Wise hire for jobs, etc.) and leveling up your account.
