Phase Fabric: Thorium Supply Guide

If you’ve hit the point where basic production is no longer enough, Phase Fabric is one of the advanced materials you start preparing for. The catch is that the public tables in this source do not spell out a confirmed recipe or usage chain, so the right approach is to set up the supporting economy around Thorium and then verify the exact Phase Fabric production step in your game client. This guide walks you through that setup so you can make advanced electronics and self-repairing structures practical.

Unlock Thorium first and treat it as your late-game foundation

Start with Thorium before you think about Phase Fabric. Thorium is an industrial resource used in advanced crafting and power generation, and it sits at the center of the late-game economy on both Serpulo and Erekir. On Serpulo, it feeds high-end materials such as Surge Alloy and Phase Fabric, and it also powers the Thorium Reactor. On both campaign worlds, it appears as pinkish ore veins, with Erekir’s ore matching the item’s own shades and Serpulo’s looking a little darker and more purple.

That makes Thorium your real bottleneck, not Phase Fabric itself. If your map progression cannot supply Thorium consistently, every later factory you build will be starved. So before you expand into advanced production, make sure your next sector and your current base are both set up to hold a steady stock of Thorium.

Set up a steady Thorium supply instead of trying to hand-mine it

Do not plan around unit mining here. Starting from version 6.0, no units can mine Thorium for balance reasons, so your supply has to come from dedicated mining drills and conveyors. That changes the way you should build: treat Thorium like a proper industrial input, not a field resource you pick up occasionally when a unit passes by.

The practical move is to claim Thorium veins early, place drills directly on the ore, and route the output into storage and transport before you spend anything on advanced crafting. Because Thorium appears in distinct veins across multiple campaign sectors on both Serpulo and Erekir, you should prioritize sectors that let you secure it close to your main factory line. Once you have it, keep the flow continuous. A late-game line that depends on Thorium should never wait on a single overloaded belt or an unprotected mine.

Here’s the part to keep in mind as you scale: Thorium is not just a crafting ingredient. It is also fuel for the Thorium Reactor, and reactors provide substantial energy output but require appropriate cooling and infrastructure to operate safely. That means Thorium production, power, and coolant planning all belong in the same design discussion. If you separate them too early, one problem will usually choke the others.

Verify the Phase Fabric recipe in your current game before building around it

This is the step where a lot of players waste time: they start designing a factory around a recipe they have not personally confirmed. Don’t do that here. The authoritative recipe entry names a Phase Weaver recipe that outputs Phase Fabric, but it does not list the inputs. The regional tables for Phase Fabric also leave production and usage entries empty, so they do not give you a reliable build chain to copy.

The important decision is not how to memorize a table, but how to avoid building the wrong factory. Open the game client or another primary reference and confirm the exact inputs for Phase Fabric before you lay down belts, power lines, and storage. If you skip that step, you risk building a Thorium-powered chain that looks ready but cannot actually start.

Use Phase Fabric where advanced electronics and self-repair matter most

Once you have Phase Fabric, spend it where it matters. It is described as being used in advanced electronics and self-repairing structures, which tells you exactly how to think about it: this is a premium resource for systems that improve durability and automation.

Do not scatter it into low-priority construction just because you finally have some. Save it for the builds that either unlock new capability or make your base harder to break. If you are deciding between an ordinary expansion and an advanced block that improves survivability or electronic infrastructure, put the Phase Fabric into the latter. That is where its value shows up.

The same logic applies if you are using it to support other high-end production paths. Phase Fabric is an advanced material, so treat it like one. It should go into the parts of your base that help you stay alive, scale production, or keep automation running when the front line gets messy.

Scale only after your Thorium and power infrastructure can keep up

When your Phase Fabric chain stalls, the fix is usually upstream. Add more Thorium extraction, better transport, and better power stability before you add more downstream machines. Thorium is already doing double duty in advanced crafting and reactor power, so if you overload it, the whole late-game economy starts to wobble.

Build your Thorium network so it can feed both production and energy without constant intervention. Keep the reactor side safe with the right cooling and infrastructure, and do not expand Phase Fabric consumption faster than your Thorium mines and power grid can support it. That way your factory grows in a controlled way instead of collapsing under its own demand.

The best rule is simple: stabilize Thorium first, confirm the Phase Fabric recipe second, and only then scale the line. If you follow that order, Phase Fabric stops being a vague goal and becomes a real, reliable part of your build plan.
