Understanding the Shard of Time Quest
The Shard of Time in Fisch is a mythical item. You cannot simply buy it from a merchant. It is a key component used to craft Merlin’s Staff, which is one of the best rods currently in the game.
To get the shard, you must venture into the Mineshaft. If you haven’t been there yet, the Mineshaft is located inside the Desolate Deep area. Once you are inside, you need to hunt for three smaller ingredients. Let’s break down how to get each one.
Step-by-Step Guide to Finding the Shard of Time
Here is how you can gather all three pieces to complete the puzzle.
How to Get the Radiant Crystal?
The first item you need is the Radiant Crystal. This item is found by fishing in the water inside the Mineshaft.
Since this item is of “Mythical” rarity, it can be very hard to catch with a basic rod. You might be fishing for a long time if you rely only on luck. However, there is a secret method to get it faster.
Pro Tip for Fast Catching:
If you have the Rod of the Forgotten Fang, use it here!
- Equip the Rod of the Forgotten Fang.
- Wait for an Aurora Totem event (or pop a totem if you have one).
- Get three “perfect” catches in a row.
- Catch a Legendary fish.
If you do this, the rod’s passive ability will activate, and you are almost guaranteed to get the Radiant Crystal for free. If you don’t have this rod, just keep fishing with your best Luck rod until it drops.

How to Find the Rough Geode?
The second piece of the puzzle is the Rough Geode. You cannot fish for this one. Instead, you need to look for piles of rubble (rocks and wood) scattered around the Mineshaft floor.
To get this item, you must have a Spear. If you don’t have a spear equipped, you won’t be able to break the rubble.
What to do:
- Equip your Spear.
- Walk around the Mineshaft and look for piles of rocks.
- Interact with the pile to start a mini-game.
- Complete the mini-game successfully to smash the rubble and loot the Rough Geode.
How to Locate the Cut Gem?
The final piece is the Cut Gem. This is the trickiest one because it involves a moving object.
Inside the Mineshaft, you will see a minecart moving along tracks in a circle. You need to stop it.
Here is the trick:
- Follow the tracks until you see a diversion (a split in the track) near an NPC.
- Look for a switch near the NPC.
- Interact with the switch to change the tracks.
- Wait for the minecart to come around. It will hit the diversion and crash into the wall.
- Walk up to the crashed cart and press “E” (or interact) to pick up the Cut Gem.

Assembling the Shard of Time
Once you have the Radiant Crystal, the Rough Geode, and the Cut Gem in your inventory, you are ready to finish the quest.
Go to the center of the Mineshaft. You will see a pedestal (a stone stand). Approach it and place all three items into their designated slots.
Once you place the final item, the dark Mineshaft will light up! The Shard of Time in Fisch will spawn right in front of you. Collect it, and you are now ready to craft Merlin’s Staff.
Frequently Asked Questions
Here are some common questions players have about this quest.
Where is the Mineshaft located in Fisch?
The Mineshaft is located within the Desolate Deep. To get there, you need to travel to the Desolate Deep area first. Look for a cave entrance that leads into the Mineshaft zone. Be careful, as navigating the deep ocean can be dangerous without the right boat.
What is the Shard of Time used for?
The Shard of Time is the main ingredient required to obtain Merlin’s Staff. This is a powerful magical fishing rod that offers unique stats and passive abilities, making it a top choice for high-level players.
Do I need a specific rod for the Radiant Crystal?
No, you do not strictly need a specific rod. You can catch the Radiant Crystal with any rod, but it is very rare. Using a rod with high “Luck” stats or using the Rod of the Forgotten Fang trick mentioned above will save you a lot of time.
Can I trade the Shard of Time?
Currently, quest items like the Shard of Time are usually bound to your character so you can use them for crafting. It is best to farm the items yourself to ensure you can complete Merlin’s quest.
What if I lose one of the items?
If you disconnect or lose an item before placing it on the pedestal, you will likely need to repeat the specific step to get that item again. For example, if you lose the Cut Gem, you may need to derail the minecart again.
Conclusion
Getting the Shard of Time in Fisch is a fun adventure that takes you away from just fishing and into solving puzzles. By gathering the Radiant Crystal, Rough Geode, and Cut Gem, you are proving you have mastered the Mineshaft.
Now that you have the shard, head over to Merlin and craft that powerful staff!
