Thermal Core has two sources in Palworld 1.0, and knowing which to use is the whole game with this material. You can craft it at the Production Assembly Line II from Technology Level 59 - four Flame Organ, eight Coal, two Corrosive Solvent, and two Hexolite per core - or you can farm it off Aegidron, which drops one to two at a 100% rate every kill. The craft is a punishing 500,000-work grind that eats two other endgame materials, so for most players the Aegidron route is faster. This guide covers both, when each makes sense, and every weapon, armor piece, ammo type, and gadget Thermal Core builds - including the Wing Pack glider and the AI Core.
Thermal Core is one of the core 1.0 assembly-line materials - see our new resources and materials guide for how the whole chain fits together.

Craft It or Farm It? The Key Decision
Unlike most 1.0 materials, Thermal Core is not craft-only - and the craft is expensive enough that farming is usually the better call. Here are your three routes:
Route | Cost per core | Verdict |
|---|---|---|
Craft it | 4 Flame Organ, 8 Coal, 2 Corrosive Solvent, 2 Hexolite per core; 500,000 work | Reliable but slow, and it burns two other endgame materials |
Farm Aegidron | Kill or capture an Aegidron; 1-2 cores per kill at 100% | Faster if you have a strong team - no Corrosive Solvent or Hexolite cost |
Farm Jetragon | Kill or capture Jetragon | A secondary source you will hit anyway while hunting the legendary |
The math favors farming. A single craft costs 2 Corrosive Solvent and 2 Hexolite - both endgame materials you would rather spend elsewhere - on top of a 500,000-work craft that crawls even with strong Pals. Meanwhile, one Aegidron kill hands you one or two cores for free, at a guaranteed 100% rate. If you can beat Aegidron, farm it; only fall back on crafting if you are short on combat power or already swimming in Corrosive Solvent and Hexolite.
The Craft Recipe and Ingredients
If you do craft it, the recipe is 4 Flame Organ + 8 Coal + 2 Corrosive Solvent + 2 Hexolite, unlocked at Technology Level 59 for 3 points and made at the Production Assembly Line II. The in-game description calls it a high-temperature reaction core containing vast thermal energy, used as a power component in advanced devices. The two hurdle ingredients are Corrosive Solvent (crafted from Venom Gland and Sulfur) and Hexolite (a World Tree ore), which is exactly why the craft is a materials drain. Flame Organ and Coal are cheap by comparison - a Flambelle on a Ranch keeps Flame Organs flowing.
Farming Thermal Core off Aegidron
Aegidron is the best Thermal Core source in the game. It is a Dragon and Ground Pal that drops one to two Thermal Cores at a 100% rate whether you kill or capture it, so a farming loop on Aegidron stocks you far faster than the assembly line. Bring a strong team - Aegidron is a powerful high-level Pal with an explosive-heavy kit - and exploit its Dragon-Ground typing.
Two multipliers make the farm even better. First, capturing then butchering an Aegidron with a Meat Cleaver rolls its drop table twice, so one capture can yield up to four cores. Second, a Pal carrying the Service-Minded or Lavish Hospitality passive boosts those drops by 50% or 100% - our Service-Minded guide covers building that butcher line. Jetragon also drops Thermal Core, so you will pick some up while hunting the fastest legendary - see our legendary locations guide for where to find it.
The efficient loop is to build a raid-style base near an Aegidron spawn, keep a Summoning Altar or a fast-travel point close, and cycle kills with a strong Dragon or Ice team. Because Aegidron is a heavy hitter with an explosive kit, bring gear that resists explosions and status healing - the fight is a wall for underleveled players but trivial once your roster is built. Every clear banks one to two cores at zero material cost, so an hour of Aegidron farming outpaces days of the assembly-line craft while leaving your Corrosive Solvent and Hexolite untouched for other recipes.
Weapons That Need Thermal Core
Thermal Core is the heat-and-energy weapon material. Every one of these draws on it:
Weapon | Thermal Core | Notes |
|---|---|---|
Overheat Rifle | 5 | The heat-themed endgame rifle |
Prototype Shotgun | 5 | Best ammo-economy shotgun |
Charge Rifle | 5 | Precision charge weapon |
Energy Shotgun | 5 | Close-range energy weapon |
Tactical Grenade Launcher | 5 | Rapid-fire AoE launcher |
Plasma Cannon | 4 | Heavy energy cannon |
Laser Gatling Gun | 3 | Sustained-fire gatling |
The Overheat Rifle is the signature use - a heat-themed rifle that also eats Cryogenic Coolant to balance its temperature. For which of these weapons is worth building first, see our weapons tier list.
Ammo That Needs Thermal Core
Several ammo types run on it too, so it stays an upkeep cost once you switch to energy weapons:
Ammo | Feeds |
|---|---|
Rocket Ammo | Feeds the Rocket Launcher |
Overheat Rifle Ammo | Feeds the Overheat Rifle |
Charge Rifle Ammo | Feeds the Charge Rifle |
Plasma Cartridge | General plasma-weapon cartridge |
Rocket Ammo is the notable one - keeping a Rocket Launcher fed for raid adds quietly consumes Thermal Core, so factor it into your stockpile before a boss farming session.
Armor, Gear, and the Wing Pack
The non-weapon uses are where Thermal Core demand really spikes - especially one gadget:
Item | Thermal Core | What it is |
|---|---|---|
Wing Pack | 20 | The 1.0 glider - by far the biggest single Thermal Core sink |
Heat-Resistant Ancient Armor | 6 | Top heat-resist armor for volcanic and lava zones |
Advanced Shield | 5 | The best personal shield for raids |
AI Core | 2 | Gates nearly every top weapon and structure |
Heat Resistant Hexolite Armor | 2 | Mid-tier heat-resist armor |
The Wing Pack is the single biggest Thermal Core sink at 20 per craft - a huge cost, but the 1.0 glider is worth it since it lets you fly without using a Pal slot. The AI Core (2 each) is the other priority, since it gates nearly every top weapon and structure. Add the heat-resist armor tiers for volcanic and lava zones, and Thermal Core turns out to feed a very broad slice of the endgame.
Where Thermal Core Sits in the Material Chain
Thermal Core is one of the deepest 1.0 assembly-line intermediates, and it sits near the top of a chain that compounds into itself. The order runs Cryogenic Coolant (Level 31), Corrosive Solvent (Level 37), Bio Battery (Level 44), Computer (Level 50), and Thermal Core (Level 59), with AI Cores at Level 67 built on top. The trap is that Thermal Core's own recipe consumes Corrosive Solvent from two tiers down, so if you crafted your way up the chain you are spending a mid-tier material to make a late one - another reason the Aegidron farm is the smarter play. Thermal Core then feeds directly into the AI Core, which gates nearly every top weapon and structure, so a Thermal Core shortage quietly stalls the entire endgame arsenal. Build your Production Assembly Line II early and start banking cores well before you need AI Cores in bulk. Our Bio Battery guide covers the sibling material lower down the chain.
How Much Should You Stockpile?
Add up the demand and Thermal Core is a material you will burn dozens of. The Wing Pack alone wants 20, the Heat-Resistant Ancient Armor set adds more, every energy weapon costs 3 to 5, and AI Cores (which you need many of) take 2 apiece. Because the craft is so slow and expensive, the practical plan is to farm Aegidron in bulk rather than craft - set up a farming loop, use capture-and-butcher for double drops, and bank the cores in a chest near your Ancient Workbench. Given its high 12,290 Gold sell value, resist the urge to sell spares; you will want every one for the Wing Pack, AI Cores, and heat gear.
Tips and Common Mistakes
- Farm Aegidron instead of crafting. It drops 1-2 cores at 100% per kill, far cheaper than a 500,000-work craft that eats Corrosive Solvent and Hexolite.
- Capture and butcher for double drops. One Aegidron capture plus a Meat Cleaver roll can net up to four cores.
- Save your Corrosive Solvent and Hexolite. The craft burns both - only craft if you are short on combat power to farm.
- Prioritize the Wing Pack and AI Cores. They are the biggest and most important sinks; plan your cores around them.
- Use strong Pals if you do craft. At 500,000 work per core, weak workers make the line unusable.
- Do not sell spares. The 12,290 Gold looks tempting, but endgame demand is high and there is no cheap resupply.
- Grab cores off Jetragon too. You will hunt the legendary anyway, and it is a bonus source.

FAQ
How do you get Thermal Core in Palworld?
Two ways: craft it at the Production Assembly Line II (Technology Level 59) from 4 Flame Organ, 8 Coal, 2 Corrosive Solvent, and 2 Hexolite, or farm it off Aegidron, which drops one to two at a 100% rate every kill. Jetragon also drops it. Because the craft is slow and expensive, farming Aegidron is usually the better option.
What is the best way to farm Thermal Core?
Kill or capture Aegidron - it drops one to two Thermal Cores at a guaranteed 100% rate. Capturing then butchering it with a Meat Cleaver rolls the drop table twice for up to four cores, and a Service-Minded or Lavish Hospitality passive boosts that further. This beats the 500,000-work craft that also consumes Corrosive Solvent and Hexolite.
What is the Thermal Core recipe?
4 Flame Organ, 8 Coal, 2 Corrosive Solvent, and 2 Hexolite make one Thermal Core at the Production Assembly Line II, unlocked at Technology Level 59 for 3 points. The Corrosive Solvent and Hexolite are the expensive parts, which is why many players farm it off Aegidron instead of crafting.
What is Thermal Core used for in Palworld?
Heat and energy gear. It feeds weapons (Overheat Rifle, Prototype Shotgun, Charge Rifle, Plasma Cannon, Laser Gatling Gun and more), their ammo, heat-resistant armor tiers, the Advanced Shield, the AI Core, and the Wing Pack glider - which alone needs 20 Thermal Cores.
Which Pals drop Thermal Core?
Aegidron and Jetragon. Aegidron is the reliable farm, dropping one to two at a 100% rate on every kill or capture. Jetragon drops it too, so you will collect some while hunting the fastest legendary in the game. No other common source exists, so these two are your farming targets.
Is it better to craft or farm Thermal Core?
Farm it, in most cases. Crafting costs 2 Corrosive Solvent and 2 Hexolite per core plus a 500,000-work craft time, while one Aegidron kill gives 1-2 cores for free at 100%. Only craft if you cannot beat Aegidron yet or you have a surplus of the two ingredient materials.
How much Thermal Core do you need?
Dozens over the endgame. The Wing Pack alone needs 20, Heat-Resistant Ancient Armor takes 6, each AI Core needs 2 (and you need many AI Cores), and energy weapons cost 3 to 5 each. Farm Aegidron in bulk and bank the cores rather than crafting them one slow batch at a time.
