The Fisch Luminescent Cavern Update is one of the biggest updates the game has seen since its original developers returned.
After months of smaller patches, this update introduces a brand-new area, new fishing rods, fresh quests, a full bestiary, and the long-awaited return of Admin Abuse Events.
To build the hype, the Fisch devs even hosted a special Discord stage event on September 19, 2025, where leaks and the official Luminescent Cavern trailer were revealed. Now the countdown is on for release day.
