The Ancient Material Synthesizer is Palworld 1.0's endgame automation payoff: place it, connect power, assign one Pal with Mining or Lumbering level 6 or higher, pick a material, and it produces that ore or hardwood forever - no manual node farming ever again. The catch is the build. It sits at the top of a long crafting chain that runs through the Ancient Furnace, Pal Alloy Ingots, and World Tree materials, so getting there is a genuine endgame project.
This guide lays out the whole pipeline in order: what the synthesizer needs, how to build the Ancient Furnace that feeds it, the ingots, the World Tree materials, and the Rainbow-passive trick that makes mining there possible. Follow it top to bottom and you build the chain once, then never mine by hand again.
Synthesizer at a Glance
Question | Answer |
|---|---|
What does it do? | Produces a chosen ore or hardwood endlessly at your base, hands-free |
Power | Must be connected to an electrical source |
Assigned Pal | Mining 6+ for ores, Lumbering 6+ for wood (Anubis is an ideal pick) |
Output speed | Scales with the assigned Pal's actual work stat |
Build cost | Ancient Civilization Cores plus a large batch of Pal Alloy Ingots |
Gated behind | The Ancient Furnace and World Tree materials (full chain below) |
What the Synthesizer Actually Does
Once built and powered, the synthesizer replaces an entire mining node for whatever material you assign it. Wire it to electricity, drop in a single Pal with a Mining stat of 6+ (for ores) or a Lumbering stat of 6+ (for hardwood), choose the output, and walk away - it generates that resource continuously with no pickaxe work. Output speed scales directly with the assigned Pal's work stat, so a high-tier worker like Anubis turns it into a serious supply line. Once it is running for a material, you can demolish the redundant mining nodes on your base and reclaim the space.
Crafting the Synthesizer: The Materials
Unlock the synthesizer in the Technology tree, then gather two gating materials:
Material | Quantity | Source |
|---|---|---|
Ancient Civilization Cores | 10 | Pal expedition sites, raid bosses, oil rigs |
Pal Alloy Ingots | 50 | Crafted at the Ancient Furnace (see below) |
Ancient Civilization Cores come from the same endgame content you already run for other rewards, so they accumulate naturally. The 50 Pal Alloy Ingots are the real gate - they require the Ancient Furnace and a chain of World Tree materials, which is where most of the work lives.
Step 1: Build the Ancient Furnace
Pal Alloy Ingots can only be smelted at the Ancient Furnace, a high-tier crafting station unlocked deep in the Technology tree. Its own recipe is demanding:
Material | Notes |
|---|---|
Corulum Ingots | Smelted at a normal furnace from Corulum ore and coal |
Ancient Civilization Cores | Same sources as the synthesizer - farm a surplus |
Thermal Cores | Made on Production Assembly Line II from flame organs, coal, hexalite, and corrosive solvent |
Computers | Made on the assembly line from circuit boards, Pal steel, carbon fiber, and bio batteries |
Both sub-components branch further: corrosive solvent is sulfur and venom run through the assembly line, and bio batteries need electric organs, refined ingots, and more carbon fiber. Build out those production lines first so the furnace recipe does not stall halfway.
Step 2: Craft Pal Alloy Ingots
The Ancient Furnace needs two assigned Pals to run: one with a Kindling trait and one with a Chilling (Ice) trait, both level 6 or higher in that work suitability. Without both, the furnace will not produce. With them assigned, each Pal Alloy Ingot draws on these ingredients:
Ingredient | Where to get it |
|---|---|
Sulfurite | A mining site at your base, or unlock the recipe in the Technology tree |
Pal Metal Ore | Mined in the World Tree region (see the Rainbow-passive step) |
World Tree Holy Water | Dropped by Pals defeated or captured inside the World Tree |
Two of the three come only from the World Tree, which is why opening that region is a prerequisite for the whole chain.
Step 3: Unlock the World Tree
Pal Metal Ore and World Tree Holy Water both live inside the World Tree endgame region, which is gated behind its own questline - defeating every Tower Boss, then completing the Panthalus quest (crafting the Echoing Flute from four Echobones, catching the whale, and dropping the barrier at the terminal). Our World Tree guide walks the full unlock step by step. Once inside, Holy Water drops at a steady rate from the Pals you defeat or capture there, so that half of the requirement is easy to top up.
Step 4: The Rainbow Passive Trick for Pal Metal Ore
Mining in the World Tree has a catch that stops most players cold: the ore and resource nodes shatter and vanish the instant you approach unless a specific condition is met. The fix is to keep a Pal carrying a Rainbow (Legendary) passive in your party - these passives share the line "World Tree resources will not vanish when approached," and with one active an aura appears around your character that keeps the nodes intact so you can mine them normally.
How to get a Rainbow-passive Pal:
- Hatch an Omnium Egg found scattered around the World Tree zone - the reliable route.
- Rarely, catch one directly from certain Pals in the same region that already carry the passive.
Keep only that Pal out (or all Pals stowed) while mining - an unequipped Pal wandering near the nodes can still trigger the despawn. With the aura up, Pal Metal Ore comes in bulk per run.
The Full Chain, Summarized
The whole pipeline, bottom to top:
Stage | What you need |
|---|---|
Ancient Furnace | Corulum Ingots, Ancient Civilization Cores, Thermal Cores, Computers |
Pal Alloy Ingot (x50) | Sulfurite, Pal Metal Ore, World Tree Holy Water, plus Kindling + Ice Pals to run the furnace |
Ancient Material Synthesizer | 10 Ancient Civilization Cores, 50 Pal Alloy Ingots |
Daily use | Power, one Pal at Mining or Lumbering level 6+ |
Build the furnace, grind through the ingots once, and the synthesizer pays that effort back for the rest of your save - one device permanently replaces the manual farming of its material.
Tips and Common Mistakes
- Build the production lines before the furnace. Thermal Cores and Computers each branch into sub-recipes - set those assembly lines up first so the Ancient Furnace recipe does not stall.
- Assign both furnace Pals. The Ancient Furnace needs a Kindling Pal and an Ice Pal at once; missing either stops all ingot production.
- Never mine the World Tree without a Rainbow passive. The nodes despawn on approach otherwise, wasting the whole trip.
- Keep only the Rainbow Pal out. An unequipped Pal near the nodes can still scare them off even when your aura is active.
- Farm Ancient Civilization Cores in bulk. Both the furnace and the synthesizer want them, so stockpile during raids and expeditions rather than making two trips.
- Assign a high-stat Pal to the finished synthesizer. Output scales with the worker's stat, so a Mining or Lumbering specialist like Anubis maximizes the yield. Our breeding guide covers building one.

FAQ
What does the Ancient Material Synthesizer do in Palworld?
Once built, powered, and staffed with a single Pal at Mining or Lumbering level 6 or higher, it produces a chosen ore or hardwood endlessly at your base with no manual mining. Output scales with the assigned Pal's work stat, and one synthesizer can replace an entire mining node for its material.
What materials does the Ancient Material Synthesizer cost?
10 Ancient Civilization Cores and 50 Pal Alloy Ingots. The cores come from expedition sites, raid bosses, and oil rigs, while the Pal Alloy Ingots must be crafted at the Ancient Furnace from Sulfurite, Pal Metal Ore, and World Tree Holy Water.
How do you craft Pal Alloy Ingots?
At the Ancient Furnace, which needs two Pals assigned at once - one with Kindling and one with Chilling (Ice), both level 6 or higher. Each ingot uses Sulfurite, Pal Metal Ore, and World Tree Holy Water, two of which come only from the World Tree region.
Why do my Pal Metal Ore nodes keep disappearing?
World Tree resource nodes shatter and vanish on approach unless you have a Pal with a Rainbow (Legendary) passive in your party, which projects an aura that keeps them intact. Get one by hatching an Omnium Egg from the World Tree area, and keep only that Pal out while mining so an unequipped Pal does not scare the nodes off.
What Pal is best for the synthesizer?
Any Pal with a Mining or Lumbering work suitability of 6 or higher works, but since output scales with the stat, a high-tier worker like Anubis maximizes production. Match the Pal's skill to the output: Mining for ore, Lumbering for hardwood.
Is the Ancient Material Synthesizer worth it?
For an endgame base, yes. The crafting chain is long, but once built the synthesizer produces its material forever with no manual farming, letting you demolish redundant mining nodes and reclaim base space. It is a one-time grind that pays back for the rest of your save.
