The Derelict Ether Furnace is a standard Quest in Xenoblade Chronicles 3: Future Redeemed. It appears shortly after learning how to upgrade your weapons with Bladestone Fragments with Riku. It’s not your typical Quest because you need to gather materials to create parts, but you only need to make the correct part. Finding the materials is the second part of the challenge, but it’s not too difficult if you know where to look. Everything you need can be gathered without fighting as long as you know where to look. Here’s what you need to know about how to complete The Derelict Ether Furnace quest in Xenoblade Chronicles 3: Future Redeemed quest, and start forging Rank V Gems.
Starting The Derelict Ether Furnace Quest
Before you begin The Derelict Ether Furnace, you must have completed Riku’s Workshop and upgraded one of your weapons. Head outside the Command Center and look to the left of the entrance to find the ether furnace. You passed it during the tour of Colony 9, but you can now interact with the furnace to begin diagnosing what is wrong. After Nikol and Shulk take a look, the solution is to replace some parts to see what was broken. To find what you need to create the parts, interact with the furnace after the quest officially begins.

Each of the current replacement parts requires materials that you can find in Yesterdale and the Aurora Shelf. None of them need combat, and you likely already have some of the materials on hand. The parts and the materials they require are:
Pure Ether Extractor
- Rabbit Diode x3
- Fluid Cranker x3
- Twin Generators x3
Multi-Function Craft Core
- Wool Rock x5
- Rainbow Zirconia x2
- Fluid Cranker x3
- Warning Lamp x5
High Output Reactor
- Demon Marble x2
- Twin Generators x3
- Magnet Clay x2
- Wool Rock x2
Rapid Cooling Device
- Warning Lamp x5
- Magnet Clay x2
- Rainbow Zirconia x2
Other than exploring and collecting items, there’s no other way to get these materials. You can Fast Travel between areas if you want the items to respawn. Their locations are:
- Vermilion Woods: Demon Marble, Warning Lamp, Twin Generators
- Aurora Shelf: Fluid Cranker
- Yesterdale: Wool Rock, Magnet Clay, Rabbit Diode, Rainbow Zirconia
How to Complete The Derelict Ether Furnace
You only need to replace one part out of the four to complete the quest. The High Output Reactor is the one that tends to be the correct answer, saving you time and effort. Most of the parts can be gathered in Yesterdale, but you can always check the Anti-Air Battery if you need Wool Rocks and Magnet Clay. Mechanical and ore collectibles are going to contain what you need rather than plants or fossils.
After repairing the Derelict Ether Furnace, the quest will be complete. You will be able to craft Rank V Gems as long as you have the Rank IV stage complete and the necessary materials.
Hopefully, this guide has given you everything you need to know to complete The Derelict Ether Furnace quest in Xenoblade Chronicles 3: Future Redeemed quest. If you haven’t started playing the new Expansion Pass DLC, it’s a good time to get started. Should you be rusty and not remember much about how to play, you can always start up the main game and get some practice before coming back.
