Corrosive Solvent is one of the crafting materials introduced with the Palworld 1.0 update, and it sits behind a chunk of the game’s late-game gear. If you want Thermal Cores, the Tactical Grenade Launcher, a Katana, or any of the lightweight armor sets, you eventually have to make a steady stream of this stuff. The good news is that the recipe itself is short.
Quick answer: Unlock Corrosive Solvent in the Technology tree at Level 37 (2 Technology Points), then craft it at a Production Assembly Line using one Venom Gland and one Sulfur per unit.
Unlock Corrosive Solvent at Technology Level 37
Before you can craft anything, the recipe has to be unlocked in the Technology tab. Open the menu, go to Technology, and scroll down to the Level 37 tier. Highlight Corrosive Solvent and confirm the unlock. It costs 2 Technology Points.
The in-game description lists it as a dangerous chemical solvent with strong decomposing properties, used for precision processing and special treatments. It’s a Common-rarity Material that stacks up to 9,999 and sells for 720 Gold each, so there’s no downside to keeping a large reserve.
Craft Corrosive Solvent at the Production Assembly Line
Corrosive Solvent is made at a Production Assembly Line. The Production Assembly Line II, Advanced Workshop, and Ancient Workbench can all produce it too, so any of them works if you’ve built one. Each unit needs just two ingredients.
| Requirement | Detail |
|---|---|
| Unlock level | Technology Level 37 (2 Technology Points) |
| Crafting station | Production Assembly Line (or II / Advanced Workshop / Ancient Workbench) |
| Materials per unit | Venom Gland x1, Sulfur x1 |
| Workload | 150 |
Where to farm Venom Gland
Venom Glands drop from Dark and Poison-type Pals, so hunting the right species is the fastest way to stockpile them. Reliable targets include Depresso, Killamari, Cawgnito, Helzephyr, and Menasting.
If you’d rather not fight for them, Wandering Merchants sell Venom Glands for 100 Gold apiece, which is handy when your stock runs dry. For a hands-off supply, put a Caprity Noct in a Ranch and it will produce Venom Glands over time without any hunting.
Where to farm Sulfur
Sulfur shows up as large yellow boulders in the Desert and Volcanic regions of the map. You can mine those directly for an immediate supply. If you need Corrosive Solvent in bulk, building a Sulfur Mine at a base gives you a passive long-term source instead of running out to the boulders every time.
To speed up gathering, bring a Digtoise. Its Partner Skill, Drill Crusher, tears through Sulfur deposits much faster than manual mining. You can catch a Digtoise around coordinates (-104, -104) in the desert, which makes it easy to grab one purely for resource runs.
What Corrosive Solvent is used for
Setting up a supply early pays off because Corrosive Solvent feeds into a long list of mid and late-game recipes. It’s a direct ingredient for Thermal Core, and it appears across weapons, armor, and Pal saddles.
| Category | Items that use Corrosive Solvent |
|---|---|
| Materials | Thermal Core |
| Weapons | Dark Grenade, Katana, Meteor Launcher, Pal Metal Axe, Pal Metal Pickaxe, Tactical Grenade Launcher |
| Armor | Lightweight Plasteel Armor, Lightweight Hexolite Armor, Lightweight Ancient Armor |
| Saddles | Astegon Saddle, Shadowbeak Saddle |
Some of these eat a lot of it. The Lightweight Ancient Armor alone can require 50 or more per craft at higher schematic tiers, and the Tactical Grenade Launcher needs 15 at its base recipe. Since the ingredients are cheap and easy to automate through a Ranch and a Sulfur Mine, the smart move is to keep a Production Assembly Line running batches in the background so you’re never held up when a bigger recipe demands a stack of it.
