How to Get 5 Battery Casings and Complete Astronomer Vega’s Quest in Fisch

The Astronomer Vega quest in Fisch requires you to collect five Battery Casings, but finding them is not as simple as fishing in any normal location. The items can only be obtained from a specific area, and their low catch chance means you may need to spend some time farming them. If you are working on the Eight Battery Dilemma quest and are stuck on the Battery Casings objective, this guide will show you where to go, how to unlock the area, and what to do once you have all five items.

Where to Get Battery Casings

Battery Casings can be obtained by fishing inside the Mineshaft on Sunstone Island. However, you cannot immediately enter the Mineshaft. You first need to complete the requirements given by Merlin on Sunstone Island and gain access to the mine.

Once the Mineshaft is unlocked, you can enter the area and start fishing for the required quest items. The location is important because Battery Casings are not something you should expect to find through normal fishing around Sunstone Island.

How to Unlock the Mineshaft

Your first stop should be Merlin on Sunstone Island. If you have already given Merlin all of the required shards, you should be able to select the option that gives you access to the Mineshaft.

Follow these steps:

1. Travel to Sunstone Island.
2. Find Merlin.
3. Make sure you have completed his required shard objective.
4. Select the option to access the Mineshaft.
5. Enter the newly accessible area.
6. Prepare your fishing rod.
7. Start fishing inside the Mineshaft.

If the Mineshaft option is not available, make sure you have completed Merlin’s previous requirements first.

How to Get Battery Casings

Once you are inside the Mineshaft, simply start fishing.

The Battery Casing has a reported catch chance of around 1%, or approximately 1 in 100 catches. Because of this low chance, getting five of them can take a while.

There is no guarantee that you will get one every 100 catches, either. Random drop chances mean you could get a Battery Casing earlier or go significantly longer without finding one.

The best approach is to keep fishing inside the Mineshaft until you have collected all five required casings.

How Many Battery Casings Do You Need?

For Astronomer Vega’s Eight Battery Dilemma quest, you need a total of:

• 5 Battery Casings

You do not need to stop after getting the first one. Keep fishing until your inventory contains all five.

Because of the low catch rate, it is better to commit to a longer farming session rather than repeatedly leaving the Mineshaft and coming back.

How Long Does It Take to Get 5 Battery Casings?

There is no fixed amount of time required because Battery Casings are obtained through a random fishing chance.

At an estimated 1% chance per catch, the average number of catches needed for one Battery Casing would be around 100, but this does not guarantee a drop.

For five casings, you could therefore need a substantial number of catches.

Do not worry if you go through a long streak without seeing one. Keep fishing and check your inventory occasionally to see how many you have collected.

Return to Astronomer Vega

After collecting all five Battery Casings, your next step is to return to Astronomer Vega.

You do not need to continue fishing once you have the required amount. Travel back to Vega, interact with her, and hand over the five Battery Casings.

This will complete the Battery Casing objective for the Eight Battery Dilemma quest.

The overall process is:

1. Visit Merlin on Sunstone Island.
2. Complete the required shard objective.
3. Unlock access to the Mineshaft.
4. Enter the Mineshaft.
5. Fish inside the Mineshaft.
6. Collect 5 Battery Casings.
7. Return to Astronomer Vega.
8. Hand over the Battery Casings.
9. Complete the quest objective.

Tips for Farming Battery Casings

The biggest challenge is the low catch chance, so patience is important.

A few simple tips can make the process easier:

• Make sure the Mineshaft is properly unlocked before trying to farm.
• Bring the fishing setup you normally use for reliable catches.
• Stay inside the Mineshaft instead of constantly changing locations.
• Keep fishing even if several catches pass without a Battery Casing.
• Check your inventory regularly so you know how many you still need.
• Once you reach five, return to Astronomer Vega immediately.

The main thing to remember is that Battery Casings are rare, so getting unlucky for a while does not necessarily mean you are fishing in the wrong place.

To complete Astronomer Vega’s Eight Battery Dilemma quest in Fisch, you need to collect five Battery Casings. The items can be caught by fishing inside the Mineshaft on Sunstone Island, which requires you to first complete Merlin’s requirements and unlock access to the area.

Once inside the Mineshaft, keep fishing until you have all five Battery Casings. With the reported catch chance being around 1%, getting the full set can take some time, so be prepared for a long farming session. After collecting all five, return to Astronomer Vega, hand over the Battery Casings, and complete the quest objective.
