Fisch Obelisk Puzzle Guide: How to Unlock Tidefall Castle

The Fisch Tidefall update added one of the coolest progression gates the game has seen so far, the Obelisk puzzle inside Tidefall. On paper it sounds simple. Turn in a few rare fish, open a door, move on. In reality, this puzzle stops a lot of players dead in their tracks. Exotic spawns, hidden locations, and server events make this one feel more like an endgame challenge than a side objective.

If you have been grinding Tidefall for a while and feel stuck, you are not alone. As someone who has played Fisch since before these massive updates rolled out, I can tell you this puzzle rewards patience and preparation. Some players even choose to skip part of the grind by using services like PVPBank to buy Fisch fish when they are missing just one exotic and do not want to wait through another long hunt cycle. That option aside, knowing exactly what to do makes all the difference.

This Fisch Obelisk Puzzle Guide will walk you through every step of unlocking Tidefall Castle, explain each Obelisk, and help you avoid the most common mistakes that slow players down.

What Is the Obelisk Puzzle in Fisch

The Obelisk puzzle is a progression gate tied directly to the Tidefall update. Completing it unlocks a hidden path inside Tidefall Castle, which is required to access one of the most important secret areas in the update.

Each Obelisk demands a specific fish or item from the Tidefall region. These are not random catches. Most of them are exotic rarity fish tied to specific sub areas or events. Until every Obelisk is completed, the gate inside Tidefall Castle stays locked.

Once unlocked, you gain access to the Plesiosaur area and move closer to crafting the Requiem Rod, which is one of the biggest long term goals in Fisch right now.

Where to Find the Obelisks in Tidefall

All Obelisks are located within the Tidefall region. You do not need to leave Tidefall to complete the puzzle, but you do need to explore it thoroughly.

Each Obelisk is color coded and placed in a distinct location. Learning where they are saves you a ton of time when turning items in.

The five Obelisks are Gold, Purple, Red Orange, Sky Blue, and White. Each one corresponds to a different exotic fish or item.

Gold Obelisk Location and Requirement

The Gold Obelisk is found in the Collapsed Ruins area of Tidefall. This zone is already dangerous for newer players, so be ready to move carefully.

To complete the Gold Obelisk, you need to turn in a Goldwraith. The Goldwraith is an exotic fish that spawns in the Crowned Ruins.

This fish is hunt based, meaning you may need to wait for the correct server conditions or actively search during peak spawn windows. Veteran players usually park servers here and rotate until it appears.

Purple Obelisk Location and Requirement

The Purple Obelisk sits in the main Tidefall area, directly opposite the shop. It is easy to spot once you know where to look.

This Obelisk requires an Omnithal. The Omnithal is an exotic fish found in the Sunken Reliquary.

The Sunken Reliquary is one of the deeper Tidefall sub zones, and getting consistent spawns here takes patience. Bring a solid rod and expect competition from other players hunting the same fish.

Red Orange Obelisk Location and Requirement

The Red Orange Obelisk is hidden behind the Tidefall shop. Many players miss it entirely on their first pass through the area.

To activate this Obelisk, you need to turn in a Pliosaur. The Pliosaur is an exotic fish that spawns in the Collapsed Ruins and is tied to a server event similar to major hunt bosses.

This one can be frustrating. Spawn timing is inconsistent, and the rarity is high. Expect to spend time server hopping or coordinating with friends.

Sky Blue Obelisk Location and Requirement

The Sky Blue Obelisk is located opposite the waterfall in Tidefall, near the bridge. It is one of the more scenic spots in the zone.

This Obelisk requires the Reef Titan, an exotic fish found in the Coral Bastion.

The Coral Bastion is not beginner friendly. You need strong gear and awareness of the environment. The Reef Titan is worth the effort, though, as it is tied to multiple progression systems beyond just the Obelisk puzzle.

White Obelisk Location and Requirement

The White Obelisk sits to the left of the Tidefall waterfall. It is the least intimidating Obelisk in terms of requirements but still trips people up.

Instead of an exotic fish, this one requires a Sparkling Dripstone. This is a trash item found in the Tidefall bestiary.

It sounds easy, but Sparkling Dripstone can take time if you are unlucky with drops. Make sure you are fishing consistently in Tidefall zones that list it in the loot pool.

How to Unlock Tidefall Castle After Completing the Puzzle

Once all five Obelisks are completed, the puzzle is solved automatically. There is no extra confirmation or cutscene.

Head toward the lush green covered area near Tidefall and glide across the water. You will find the Tidefall Castle entrance waiting for you.

The gate that was previously locked will now open, granting access to the inner section of the castle.

What You Get Inside Tidefall Castle

Inside Tidefall Castle, you gain access to the Plesiosaur spawn area. While the Plesiosaur can appear during hunts elsewhere, this location gives you a reliable endgame target.

The Plesiosaur is a divine secret rarity fish. Spawning it takes time, and you will need to repeatedly use totems to trigger the event.

This fish is required to craft the Requiem Rod, making the Obelisk puzzle mandatory for serious progression.

Tips to Complete the Obelisk Puzzle Faster

Do not try to do this puzzle casually without planning. It is designed to slow players down.

Focus on one exotic at a time instead of bouncing between zones.

Play during peak server hours when hunts are more active.

Upgrade your rods before attempting Coral Bastion or Collapsed Ruins hunts.

Join community servers or friends to share spawn info and reduce downtime.

Common Mistakes Players Make

The biggest mistake is assuming the puzzle can be brute forced quickly. It cannot.

Another common issue is ignoring Sparkling Dripstone until the end. Start farming it early to avoid last minute delays.

Many players also underestimate how rare Pliosaur and Reef Titan spawns are. Go in expecting a grind.

Is the Obelisk Puzzle Worth It

Absolutely. Unlocking Tidefall Castle is not optional if you want to experience the full Tidefall update.

Between the Plesiosaur access, Requiem Rod progression, and future content hooks, this puzzle is a long term investment.

It feels slow at first, but finishing it puts you ahead of the curve.

Final Thoughts on the Fisch Obelisk Puzzle

The Fisch Obelisk Puzzle is one of the most satisfying challenges added to the game. It rewards exploration, patience, and knowledge of Tidefall mechanics.

Once you unlock Tidefall Castle, the game opens up in a big way. If you are serious about Fisch, this puzzle is not something you skip. Take your time, play smart, and enjoy the process.
