Discover the best way to collect Coal Bait in Fisch! Farm Volcanic Geodes, boost your luck, and reel in rare volcanic fish.

Coal Bait is a must-have for serious fishers in Fisch. It attracts powerful volcanic fish hiding in lava pools. Without it, some of the rarest catches remain impossible. This bait isn’t found in regular shops or common fishing spots. Instead, you need to crack open Volcanic Geodes to get it. These geodes aren’t too rare, but they require the right gear.
The Magma Rod and Magnet Bait make farming easier. If you’re lucky, the Traveling Merchant might sell a few geodes for 600C$. Inside, Coal Bait grants +45 Preferred Luck, making it perfect for legendary fish like the Ashcloud Archerfish.
How To Get Coal Bait in Fisch
Coal Bait is only available from Volcanic Geodes. You cannot buy it directly from any shop. Instead, you must farm geodes or purchase them from the Traveling Merchant when available.

There are two ways to get Volcanic Geodes:
- Buy from the Traveling Merchant – Costs 600C$ per geode. The merchant’s stock changes frequently, so check often.
- Fish in lava at Roslit Volcano – Requires the Magma Rod and Magnet Bait.
After obtaining a Volcanic Geode, open it to extract Coal Bait. This bait gives -10 Resilience and +45 Preferred Luck, making it useful for catching rare fish.
Best Way To Farm Volcanic Geodes
Fishing in lava at Roslit Volcano is the most reliable method. Follow these steps to farm Volcanic Geodes efficiently:
- Equip the Magma Rod – This is required for lava fishing.
- Use Magnet Bait – It increases the chances of catching geodes.
- Fish directly in the lava pools at Roslit Volcano.
- Open every Volcanic Geode you collect to get Coal Bait.
Geodes are not extremely rare, but they do not appear consistently. If you don’t want to spend time fishing, check the Traveling Merchant whenever possible.
