To get the Undefined Magnetite Core in Fisch, start the Drylands Shopping Errand quest, buy the core from the nearby local merchant for 15,000 coins, then return to the quest giver to continue.
The Undefined Magnetite Core trips people up because it sounds like a rare fishing drop, but it is nothing of the sort. It is a shop item you simply buy during one of the first quests in the Drylands. Knowing that up front saves you from grinding the wrong way, so here is exactly where it comes from and what it costs.
Where to buy the Undefined Magnetite Core
The core is bought, not fished or farmed. When the Shopping Errand quest asks you for it, the item is sold by a local merchant — and the good news is that this seller sits very close to the NPC who hands you the quest. You do not need to comb the whole desert or run across the entire Drylands to find them.
KEY!The price is a flat 15,000 coins. That is not steep by Fisch standards, but you do want that money ready before you talk to the merchant. The seller’s exact name is not something worth memorizing here — what matters is that they are a short walk from the quest giver and sell the core outright.
Buying the core during Shopping Errand
The whole loop is short once you know it is a purchase. Start the quest, find the seller right beside the quest giver, pay up, and head back.
STEP 1/4
Start the Shopping Errand quest
Pick up the Drylands Shopping Errand quest from its quest giver; the objective will call for the Undefined Magnetite Core.
STEP 2/4
Find the local merchant nearby
Look for the seller close to the quest giver rather than searching the wider desert.
STEP 3/4
Buy the Undefined Magnetite Core
Purchase the core from the merchant for 15,000 coins and confirm it lands in your inventory.
STEP 4/4
Continue the quest
With the core bought, carry on with Shopping Errand instead of hunting for the item elsewhere.
Have at least 15,000 coins banked before you start Shopping Errand — the merchant is easy to reach, so money is the only thing that actually gates this step.

What the Undefined Magnetite Core does
Think of the Undefined Magnetite Core as a progression item, not a material you collect over and over. It exists purely to satisfy the Shopping Errand objective, and once you buy it and turn it in, the quest moves on.
It is not a regular fishing drop and it is not a repeat-farm resource like the fish and materials you gather elsewhere. This is a one-off early Drylands purchase — you pick it up to clear this stage of the questline and then you are done with it.
Common Shopping Errand mistakes to avoid
| Mistake | What to do instead |
|---|---|
| Searching the whole Drylands for the seller | Check right beside the quest giver — the merchant is close by. |
| Fishing or grinding to find the core | Buy it from the merchant; it never drops from fishing or combat. |
| Buying a different Magnetite-style item | Purchase the exact Undefined Magnetite Core the quest names. |
| Reaching the shop without enough coins | Bank 15,000 coins before you start the errand. |
Most of the trouble with this quest comes from treating it like a hunt when it is really a shopping trip. The two biggest time-wasters are searching the entire Drylands for a seller who is right next to you, and trying to fish or grind for an item that only ever comes from a shop. It also helps to read the objective carefully: only the specifically named Undefined Magnetite Core counts, so grabbing a different Magnetite-style item will not clear the step.
The last common snag is money. Players sometimes reach the merchant only to find the purchase option unavailable because they are short on coins — the 15,000 needs to be in hand before you interact with the shop.
After you buy the core
There is no detour once the core is in your bag. The next action is simply to return to the Shopping Errand quest giver and hand it over, which pushes the Drylands questline forward. From there you are free to chase later mid-game goals, but none of that is needed to finish this particular step — buy, turn in, move on.
Frequently Asked Questions
Can you fish up the Undefined Magnetite Core?
No. It is a shop-bought quest item, so you cannot catch it while fishing or earn it from combat. The only way to get it is to buy it from the local merchant during Shopping Errand.
How much does the Undefined Magnetite Core cost?
It costs 15,000 coins. That is fairly cheap compared with many other items in Fisch, but you still need the full amount ready before you approach the merchant.
Where is the merchant for the Shopping Errand quest?
The merchant is located very close to the NPC who gives you the Drylands Shopping Errand quest, so you do not have to search the desert. The seller’s exact name is not confirmed, but their proximity to the quest giver is what matters.
Do you need the Undefined Magnetite Core more than once?
No. It is a one-off purchase for this quest — you buy it, turn it in, and it is done. It is not a repeat-farm material.
