If you’re trying to complete a quest or fill out your Bestiary in Fisch, you’ve probably come across the Glass Diamond. It isn’t one of those items you’ll catch by accident while fishing anywhere on the map. Instead, it has a specific farming location, and knowing where to go can save you a lot of time.
The good news is that you don’t need a complicated setup or rare bait. As long as you’re fishing in the right place and have a bit of luck on your side, you’ll eventually reel one in. Here’s everything you need to know.
How to Get Glass Diamond in Fisch (Best Farming Location)
The Glass Diamond is a collectible item in Fisch that is used for certain quests and Bestiary progression.
Since it doesn’t appear in many fishing spots, players often spend a long time searching the wrong locations. If you’re after one, it’s best to head straight to the area where it has the highest chance of appearing.
Best Location to Get Glass Diamond
The most reliable place to catch the Glass Diamond is in the Northern Expedition region.
Once you arrive at Northern Expedition, continue your journey until you reach the Overgrowth Caves.
This is considered the best farming location for the Glass Diamond and is where most players have the greatest success finding it.
How to Reach Overgrowth Caves
If it’s your first time exploring Northern Expedition, here’s the route:
- Travel to Northern Expedition.
- Start from Northern Summit, which is the first camp located near the bottom of the area.
- Continue climbing higher through the expedition route.
- Reach the Overgrowth Caves, the second major camp in the region.
- Fish inside the cave to begin farming for the Glass Diamond.
Once you’re inside the cave, simply cast your line and keep fishing until the item appears.
Do You Need a Specific Rod or Bait?
No. One of the best things about farming the Glass Diamond is that there aren’t any special fishing requirements.
You do not need:
- A specific fishing rod
- A special bait
- Any unique weather or time conditions
This means almost any player who has access to the area can start farming immediately.
Increase Your Luck for Better Results
Although there aren’t any special requirements, Luck plays a major role.
The Glass Diamond is considered a luck-favoured catch, so increasing your fishing luck can improve your chances of obtaining it sooner.
Some ways to boost your luck include:
- Using rods with Luck bonuses.
- Equipping enchantments that increase Luck.
- Activating any available Luck buffs or event bonuses.
- Fishing during periods when you have temporary Luck boosts active.
Higher Luck won’t guarantee an instant catch, but it can reduce the amount of time you spend farming.
Best Farming Tips
If you want to get the Glass Diamond as quickly as possible, keep these tips in mind:
- Fish only inside Overgrowth Caves.
- Stack as much Luck as possible before farming.
- Stay patient, as the Glass Diamond is still a rare catch.
- Keep fishing in the same location instead of moving between different islands.
The Glass Diamond is more about patience than difficulty.
Once you know that Overgrowth Caves in the Northern Expedition is the correct location, the process becomes straightforward. There are no hidden puzzles, no special bait requirements, and no complicated quest prerequisites. Simply fish in the right spot, increase your Luck whenever possible, and keep casting until the Glass Diamond finally appears.
If you’re working on quests or aiming for 100% Bestiary completion, this is currently the fastest and most reliable way to obtain the Glass Diamond in Fisch.
