Fusion Ignitor vs Stasis Device: Which Is Easier to Craft in No Man's Sky?

Both items sell for 15,600,000 units and both have long recipe chains. So the real question is which one is easier to build with the farms you already have. For most players that’s the Stasis Device, though a Fungal Mould farm can flip it.

Side-by-side recipe breakdown

	Fusion Ignitor	Stasis Device
Base value	15,600,000 units	15,600,000 units
Shared component	Quantum Processor	Quantum Processor
Unique component	Portable Reactor	Cryogenic Chamber
Unique alloy	Geodesite	Iridesite
Hardest farm ingredient	Fungal Mould (600x)	Gamma Root (400x)
Hardest mineral	Ammonia + Uranium	Phosphorus (easy)
Gas requirements	Sulphurine, Radon, Nitrogen	Sulphurine, Radon, Nitrogen

What they share

Both require a Quantum Processor, the most complex intermediate component in either chain. It takes:

• 1x Circuit Board (100x Frost Crystal + 200x Solanium + 100x Cactus Flesh + 200x Star Bulb)
• 1x Superconductor (250x Sulphurine + 250x Radon + 250x Nitrogen + 150x Condensed Carbon)

Both also consume the same three gases (Sulphurine, Radon, Nitrogen), so one gas extractor setup covers both.

Where they diverge

Fusion Ignitor: the Portable Reactor chain

The Portable Reactor needs Liquid Explosive and Fusion Accelerant.

Liquid Explosive needs:

• Acid: 25x Mordite + 600x Fungal Mould
• Unstable Gel: 200x Cactus Flesh

600x Fungal Mould is the problem. It grows on swamp and toxic planets, or in Biodomes with swamp conditions. At that volume you need a dedicated farm. No other high-value craft needs it, so you’re building a Fungal Mould farm just for this.

The Geodesite alloy also needs Ammonia (toxic planet) and Uranium (radioactive planet). If you don’t have quick access to both planet types, you’re making extra supply runs.

Stasis Device: the Cryogenic Chamber chain

The Cryogenic Chamber needs Living Glass and Cryo-pump.

Living Glass needs:

• Lubricant: 50x Faecium + 400x Gamma Root
• 5x Glass: 200x Frost Crystal total

Gamma Root at 400x is the main farm here. It grows on irradiated planets or in Biodomes. Most established players already have it if they’ve run the NPC mission chains. Faecium is easy. Creatures drop it almost everywhere, and you only need 50x.

The Iridesite alloy needs Paraffinium, Phosphorus, and Dioxite, which come from lush, fiery, and frozen planets. All three are common planet types and the quantities are modest (50x each).

The verdict

I’d pick the Stasis Device, for two reasons:

1. Gamma Root is a simpler farm than Fungal Mould. Both need Biodomes if you don’t have the right native planet, but Gamma Root has no volume spike on the scale of 600x. The hardest single ingredient in the Stasis chain is 400x Gamma Root. The Fusion Ignitor asks for 600x Fungal Mould, which is rarer to come by.

2. Iridesite is easier to supply than Geodesite. Paraffinium, Phosphorus, and Dioxite all show up on common planet types. Geodesite needs Ammonia and Uranium, so you’re hunting for toxic and radioactive planets specifically.

When the Fusion Ignitor is easier

Fusion Ignitor wins if you already have:

• A working Fungal Mould farm (e.g., from farming Acid for other recipes)
• Easy access to toxic and radioactive planets in your home system
• No established Gamma Root farm

If both farms are zero and you’re starting fresh, the Stasis Device chain gets you to a sellable item faster.

Running both at once

Honestly, just run both. The shared ingredients (Quantum Processor, all three gases, Cactus Flesh, Star Bulb, Solanium, Frost Crystal) mean your gas setup and most of your plant farm already feed both chains. Add a Fungal Mould setup for the Portable Reactor and a Gamma Root farm for the Cryogenic Chamber, and one collection run produces materials for both items.

That roughly doubles your output per session, and the only extra infrastructure is the Fungal Mould and Gamma Root farms.

Farm	Feeds
Gas extractors (Sulphurine, Radon, Nitrogen)	Both
Cactus Flesh + Star Bulb + Solanium + Frost Crystal	Both
Fungal Mould + Mordite	Fusion Ignitor only
Gamma Root + Faecium	Stasis Device only
Pyrite, Ammonia, Uranium	Fusion Ignitor only
Paraffinium, Phosphorus, Dioxite	Stasis Device only
