Corrosive Solvent

Unlocked at Technology level 37, this bottle is the mid-game chemical that keeps showing up once assembly lines and surgery gear come online. One craft costs Venom Gland ×1 and Sulfur ×1 at a Production Assembly Line, with a workload of 150.

Farm the two inputs on separate loops. Sulfur comes from quarry and volcanic nodes. Venom Glands drop from venom Pals, so pair a hunting route with your sulfur runs instead of waiting on one base alone.

The solvent feeds a long structure list: Pal Surgery Table, Production Assembly Line II, Weapon Assembly Line II, Accumulator, and Alpha Wave Generator. Combat and tool crafts include the Katana, Meteor Launcher, Pal Metal Axe and Pickaxe, Dark Grenade, and Tactical Grenade Launcher. Armor lines for Lightweight Plasteel, Hexolite, and Ancient sets burn solvent as you climb ranks. It also sits in the Thermal Core recipe and in some legendary saddles, including Astegon and Shadowbeak.

Place it in the chemical chain so you don't stall later crafts. Cryogenic Coolant unlocks at 31, Corrosive Solvent at 37, then Bio Battery at 44. Stock solvent ahead of Surgery Table work and the Assembly Line II upgrades or those unlocks will eat your first batch overnight.
