This patch arrives alongside the countdown timer, promising fresh content for Roblox Fisch enthusiasts.
- New Luminescent Cavern
- Admin Abuse Events
- New Quests
- New Rods and Bestiary
- Fisch Codes
As per the reveal trailer, Luminescent Cavern will be an extension of the Desolate Deep. The Fisch leaks also reveal what new rods and locations are arriving with the update.
But what can you expect for now? Well, according to the Fisch Discord leaks, the key highlight of the update is the Luminescent Cavern. We have a slight hint of how the cavern is from the leaks channel. The glowing depths of the cavern open up a mysterious new area that players can climb to uncover secrets hidden beneath the waves.
After the first leak, another image showcases a shining cave, which is possibly the location where players will enter to uncover the new area. Alongside the new location, admins will be running special Admin Abuse Events, where players will get to witness new events, mutations, and exclusive special fish.
How to unlock Luminescent Cavern with all keystones
Unlocking the Luminescent Cavern in Fisch on Roblox requires collecting three specific keystones, which vary per player, from pedestals near the Mysterious Crack in Desolate Deep. Interact with the three pedestals first to identify your required keystones before hunting them down across islands.
Keystone Locations
Eight or nine keystones (sources vary slightly) are scattered; grab only the ones shown on your pedestals. Key spots include:
-
Sun Keystone: Sunstone Island, back area near the Desolate Deep entrance.
-
Volcano Keystone: Roslit Volcano at coordinates -1970, 175.4, 268, on the middle stone.
-
Skull Keystone: Forsaken Shores at -2797.5, 209, 1544.2, beside the pirate NPC.
-
Lightning Keystone: Grand Reef at -3406, 134.2, 262.2.
-
Snowflake Keystone: Snowburrow (unlock Snowcap Cave first by interacting with three cracks), inside a cave by the pine tree.
Other possibles: Fossil (Ancient Isle), Mushroom (Mushgrove), Cliff (Castaway), Turtle (Terrapin).
Access Steps
Dive from the Red Buoy on Sunstone Island with diving gear and flippers, head right past the warning sign and blue coral to the Diver NPC and pedestals. Equip each matching keystone (press E to place); the crack opens once all three are set-swim through, then cross the Mysterious River to fish.
Show fastest route to collect the three required keystones
Unlocking the Luminescent Cavern requires checking your three random pedestals at the Mysterious Crack in Desolate Deep first, then collecting only those specific keystones from nearby islands for the fastest route.
Efficient Collection Order
Prioritize proximity to minimize boat travel, starting from Sunstone Island (easy access point). A sample loop for common combos like Sun, Volcano, and Skull:
-
Sun Keystone: Land on Sunstone Island, head to the back near Desolate Deep tunnel-claim via E interaction.
-
Volcano Keystone: Boat to Roslit Volcano (-1970, 175.4, 268); glide to the middle stone pedestal (under 10 seconds from Sunstone).
-
Skull Keystone: Quick sail to Forsaken Shores (-2797.5, 209, 1544.2), grab beside the pirate NPC.
Route Tips
For farther ones, cluster by region: Group Sunstone/Roslit/Forsaken first (central ocean), then Reef/Ancient Isle, saving Snowburrow (needs Snowcap unlock) or Mushgrove for last. Use fast boats/flippers; total time under 5 minutes with practice. Return to pedestals, equip via E, and enter.
