Are you trying to figure out the new Mystery at Sunstone Fisch quest? You are in the right place. The popular Roblox game Fisch just dropped a massive update, and it has changed Sunstone Island completely. To finish this quest, you need to talk to Merlin, find hidden gems underground, and craft a powerful new tool.
The short answer: To complete the mystery, get the Merlin’s Veil buff from Merlin to see The Chasm in the water. Swim down into the Fisch Mineshaft location, find three specific gems, place them on pedestals to get the Shard of Time, and trade it to Merlin for Merlin’s Staff.
Below is your complete, step-by-step guide to mastering this event.
Key Takeaways: Quick Quest Overview
If you are in a rush, here are the most important steps you need to follow to finish the quest.
| Step | Action Required | Result/Reward |
| 1 | Talk to Merlin on Sunstone Island | Unlock quest dialogue |
| 2 | Ask for Merlin’s Veil buff | Ability to see “The Chasm” |
| 3 | Enter The Chasm (in the ocean) | Access the Mineshaft |
| 4 | Find 3 Gems (Geode, Cut, Radiant) | Quest items collected |
| 5 | Place Gems on Pedestals | Receive Shard of Time |
| 6 | Return to Merlin | Craft Merlin’s Staff |
Step 1: Finding Merlin and Getting the Buff
Your journey starts at Sunstone Island. If you visit the center of the island, you will notice Merlin looks different. He has a new form and is central to the Mystery at Sunstone Fisch quest.
When you talk to him, you will see a few options. You might see items for sale, but you can ignore those for now. You need to focus on the dialogue that helps you explore.
You must select the option to get the Merlin’s Veil buff.
This is the most important part. Without this buff, you cannot see the secret area. Think of it like putting on magic glasses. Once you have the buff, you are ready to head into the water.
Pro Tip: If you missed previous events, you can also ask Merlin to summon a Rift every 20 minutes to help you catch up!
Step 2: How to enter The Chasm in Fisch?
Now that you have the magical veil active, look at the water surrounding Sunstone Island. You are looking for a massive crack or fissure in the ocean floor.
This area is called The Chasm. Before you got the buff, it was invisible. Now, it glows and looks like a deep tear in the ground.
Swim directly into it. This is how to enter The Chasm Fisch players have been talking about. It acts like a tunnel that transports you to a brand-new underground zone.
Step 3: Exploring the Mineshaft Location
Entering The Chasm drops you into the Fisch Mineshaft location. This is a spooky, cave-like area where the main puzzle takes place.
Your goal here is to be a treasure hunter. You need to find three very specific items hidden around the cave. You cannot leave until you find them all if you want to finish the quest.
The Three Hidden Gems
You need to search the environment for these three stones:
- The Rough Geode
- The Cut Gem
- The Radiant Crystal
These aren’t in your inventory automatically. You have to look in the corners, behind rocks, and in the “nooks and crannies” of the Mineshaft. Take your time and look everywhere.

Step 4: Unlocking the Shard of Time
Once you have all three gems in your pocket, you are halfway done. Now, look around the Mineshaft for three stone pedestals (small stands).
You need to place each gem on its matching pedestal. It is like a puzzle key.
- Walk up to a pedestal.
- Place the correct gem.
- Repeat for all three.
When the final gem is placed, a magical reaction happens. You will be rewarded with the Shard of Time location item. This is a very rare material that you cannot get anywhere else.
Step 5: Crafting Merlin’s Staff in Fisch
Now that you have the Shard of Time, it is time to leave the cave. Go back to the surface and speak to Merlin again on Sunstone Island.
He will take the Shard of Time and combine it with other materials to craft the ultimate prize: Merlin’s Staff Fisch rod.
Is Merlin’s Staff Good?
Yes, it is a Stage 7 rod, which means it is very strong. It has a unique ability that changes how you fish.
The Passive Effect:
- It decreases your “control” stat by -0.2.
- BUT: When your control drops, you get a massive 30% boost to catch progress.
This means the bar might get a little shaky, but you will catch the fish much faster. It is a great trade-off for skilled players.
New Feature: The Totem Carver
The update didn’t just add a quest. There is also a new station called the Totem Carver Fisch players will love.
You can find this station near Merlin. In the past, getting specific totems was random and hard. Now, you can use materials like pearls to craft exactly the totem you need. This saves you a lot of time when you are hunting for specific fish rarities.

Frequently Asked Questions
Where exactly is the Rough Geode location?
The Rough Geode is hidden inside the Mineshaft. The spawns can be tricky, so you must check the corners of the cave room. It looks like a dull, rocky stone compared to the other shiny gems.
Can I enter The Chasm without talking to Merlin?
No. You must speak to Merlin first to get the Merlin’s Veil buff. If you do not have this buff active, the entrance to the Chasm will not appear in the water, and you cannot enter.
What does the Shard of Time do?
The Shard of Time is a crafting ingredient. Its only use right now is to be given to Merlin. He uses it to create Merlin’s Staff, which is the final reward for the Mystery at Sunstone Fisch quest.
Is the Black Market always on Sunstone Island?
No. The Black Market is a special shop that only appears on weekends. It sells random items that rotate, so you should check it every Saturday and Sunday for rare goods.
Do I need a high level to finish this quest?
You do not need a specific level to start the quest, but having a decent diving tank helps you explore the Mineshaft longer without running out of air.
Conclusion
Completing the Mystery at Sunstone Fisch quest is a fun challenge that rewards you with one of the most unique rods in the game. By getting the veil, diving into the Mineshaft, and solving the gem puzzle, you will wield the power of Merlin in no time.
