Bone Shard and Ancient Bone are crafting and quest materials in Fisch, and both come from the same type of catch if you know where to cast. The trick is to stop chasing common fish and hunt one category on purpose. Shark-type fish are the shortcut, and one location gives up both materials at once.
Quick answer: Go to the Gloomy Zone (Gloomy Crevice) and target shark-type fish only. Each shark you land can drop both Bone Shard and Ancient Bone. If you need Bone Shard alone, fish the Lower Deep and hook Atlantic Dragonfish instead.
Farm Bone Shard and Ancient Bone in the Gloomy Crevice
The Gloomy Zone, specifically the Gloomy Crevice, is the single best place to stock both materials without switching spots. Shark-type fish there act as the primary source of Ancient Bone while also handing over Bone Shard, so every shark counts toward two goals. Ignore the smaller, common catches and keep fishing until sharks spawn.
Gear that speeds up the farm
Sharks are heavy, so a weak rod slows you down. Bring a strong fishing rod, or use a harpoon gun like the Trident Striker to pull them in faster. The harpoon approach shortens the fight on each shark, which means more Bone Shard and Ancient Bone per session.
| Goal | Location | Target catch | Materials |
|---|---|---|---|
| Both materials at once | Gloomy Zone (Gloomy Crevice) | Shark-type fish | Bone Shard + Ancient Bone |
| Bone Shard only | Lower Deep | Atlantic Dragonfish | Bone Shard |
Bone Shard only: fish the Lower Deep
If your inventory is short on Bone Shard and you do not need Ancient Bone, skip the sharks entirely. Head to the Lower Deep and target the Atlantic Dragonfish, which drops Bone Shard directly. This is a cleaner run when a quest or recipe only calls for shards.
Note: This route does not provide Ancient Bone, so use the Gloomy Crevice whenever you need both.
How to confirm the drops are working
When a shark is reeled in at the Gloomy Crevice, the catch notification confirms the material drops as they land in your inventory. Open your inventory to check your Bone Shard and Ancient Bone counts climb after each shark. If the numbers are not moving, you are likely catching common fish instead of sharks, so wait for a shark spawn before committing your cast.
