The Lost Jungle expansion in Fisch has transformed what was once a simple Mossjaw bone collection quest into an elaborate underground temple adventure. This substantial update introduces multiple new NPCs including specialized merchants and spear crafters, while the main attraction remains the Forgotten Temple gate hidden beneath the jungle terrain.
Before reaching the final gate, adventurers must navigate through a complex maze system featuring five distinct puzzle chambers. Each room presents unique challenges that reward players with elemental runes essential for progression. Our comprehensive guide provides detailed strategies to conquer every obstacle and access the exclusive Mossjaw fishing area.
The Forgotten Temple, also known as the Lost Temple, is situated beneath the Jungle Island in Fisch. Navigate to coordinates -3080, 140, -1125 using your GPS to locate the island entrance. Proceed past the Spear Crafting zone and cross the bridge, then ascend the ledge and turn right toward the small cliff where you’ll discover a rope leading downward into the temple when pressing the ‘E‘ key.


Since the Forgotten Temple functions as an intricate maze, you’ll discover a detailed map carved into the ground upon arrival. Directly behind your starting position stands the Jungle Adventurer NPC – engage with her immediately to obtain the crucial Temple Eye item. This essential tool ensures you respawn at the Temple Gate checkpoint whenever you perish during puzzle attempts, saving significant backtracking time.

Now consult the temple map below and systematically approach each chamber in sequence to solve their puzzles and collect the required runes for unlocking the Lost Temple’s final gate.
1. Glyph Rune (Room I)

- Coordinates: -5237, -1757, -9622
The chamber positioned in the bottom-right section of the temple map houses the Glyph Rune. Upon arriving at the specified coordinates, you’ll encounter three parallel rows of stepping stones. Fortunately, the correct path remains consistent across attempts rather than being randomly generated.
Execute the precise stepping sequence beginning with the stone directly before you: Triangle, Square, Square, Triangle, Circle, Triangle, Square, Triangle, Circle. Following this pattern exactly will transport you to the chamber’s endpoint where you’ll acquire both the Glyph Rune and Poisonous Spearhead reward.
2. Toxic Rune (Room II)

- Coordinates: -4612, -1757, -10170
The second chamber located in the map’s top-left quadrant contains the Toxic Rune. Approaching this room reveals a movable gate displaying distinctive markings. Position yourself extremely close to this barrier while simultaneously holding the W+A or W+D keys to trigger the door mechanism and gain entry.
Once inside, immediately begin the platforming challenge by leaping across platforms and scaling ladders. Toxic water rapidly floods the chamber, and contact with this hazardous liquid results in immediate death. Successfully navigating the obstacle course and reaching the summit rewards you with both the Toxic Core and Toxic Rune.
3. Spike Rune (Room III)

- Coordinates: -5404, -1759, -10229
Proceed to the bottom-left region of the Lost Temple to tackle the third chamber’s puzzle. This challenge presents another maze configuration where the primary danger comes from wall-mounted spikes. Maintain safe distance from these deadly protrusions as they inflict instant fatal damage upon contact.
Follow these navigation instructions precisely to safely reach the chamber’s conclusion and obtain the Barbed Spearhead alongside the Spiked Rune: straight, right, left, right (continue forward), left, left, right, left, straight, left, right, right, left, right, concluding with straight movement toward your reward.

4. Vine Rune (Room IV)

- Coordinates:-5174, -1757, -10349
The fourth chamber positioned at the map’s far left edge presents more complex challenges than previous rooms. Entering reveals numerous ceiling-dangling vines that trigger interaction prompts when approached.
Avoid the temptation to engage with these deceptive vines as they cause immediate death. Instead, proceed directly toward the large tree at the chamber’s rear and ascend it. Then retrace your path utilizing your Advanced Glider or by leaping onto the concealed platform behind.
Unexpectedly, you’ll land upon a solid invisible surface. From this position, navigate toward the room’s center, leap toward the Vine Rune, and collect both it and the Vine Line accessory.
5. Water Rune (Room V)

- Coordinates: -4851, -1759, -9550
After successfully clearing all preceding puzzles, prepare for the final challenge in the fifth chamber. This room contains submerged pathways with your objective visible on the opposite side. Attempting direct traversal results in instant death.
The sole solution involves deciphering the ceiling-etched maze pattern. Align any horizontal pathway with your screen’s edge, then position your mouse cursor at the center of the vertical route you intend to follow. Maintain forward movement until encountering turns, adjust direction accordingly, realign your pointer, and repeat this process until reaching the destination. Successfully navigating this aquatic maze rewards you with both the Murky Thread and Water Rune.
How to Open Forgotten Temple Door to Get to Mossjaw Rest in Fisch

After gathering all five elemental runes, activate your Temple Eye to return to the Temple Gate checkpoint. If you’ve explored this area thoroughly, you’ve likely observed the multi-colored pedestals flanking the massive door structure.
Should you experience difficulty locating the Forgotten Temple Gate in Fisch, proceed to the opposite extremity of the fourth chamber pathway. Now access your hotbar containing the collected runes and position them on their designated stands:
- Light Grey Rune (Left side, Left): Glyph Rune
- Dark Grey Pedestal (Left side, Middle): Spiked Rune
- Light Green (Left Side, Right): Toxic Rune
- Dark Green Pedestal (Right Side): Vine Rune
- Blue Pedestal (Right Side): Water Rune

Immediately upon positioning the fifth rune on its corresponding pedestal, the enormous door mechanism activates, granting access to Mossjaw Rest. Proceed through the gateway, descend the staircase, and you’ll discover an expansive pool awaiting exploration.
This newly accessible aquatic environment shares its creature catalog with the Lost Jungle region. Interestingly, the exclusive exotic and secret specimens from this bestiary can only be caught within Mossjaw Rest. Indeed, this location serves as the exclusive spawning ground for Mossjaw during special events, featuring both the exotic Mossjaw and the elusive Elder Mossjaw variants. The fishing mechanics operate similarly to the Kraken encounter system in Fisch.
Thus concludes our comprehensive guide to conquering all temple puzzles and unlocking the Forgotten Temple Gate in Fisch. Are you prepared to overcome every chamber challenge specifically to pursue these unique aquatic specimens? Share your thoughts in the comments section below.
