How to farm Acid in Once Human
There are multiple ways to farm Acids in Once Human:
Method 1 — Enemy drops

You can defeat enemies like Gnawner, Charred Maniac, and others to get Acid as an item drop. You can boost that drop rate of Acid from such enemies by eating food items like the Preserved Deviated Chops as then, killing enemies grants +50% Acid.
To make the method more efficient, you can also activate Workshops like the Blackfell Oil Fields and others, as then, you don’t have to hunt enemies, and they will come to you.
Method 2 — Building an automated Acid Farm

Building an automated Acid farm in Once Human requires much work and forces you to choose a particular specialisation. For it to work, you need:
- Water Pump
- Osmosis Water Purifiers
- Brewing Barrels
- A lot of electricity
Apart from the above facilities, you must also make your base in Stardust Polluted Zones so that your Water Pump collects Polluted Water, which you can use in your reverse Osmosis Water Purifiers to transform into Unpurified Acid and Purified Water.
After that, you must place the Pure Water and the Unpurified Acid into the Brewing Barrels to obtain Acids. This is a good method of farming Acids on a large scale, but I don’t like it because it requires a lot of facilities.
Method 3 — Sulphur Chemist

You can unlock the Sulphur Chemist specialisation to craft Acid using Sulphur and Energy Links via a Synthesis or Advance Synthesis Workbench.

The Sulphur Chemist is the best method for farming a ton of Acids in Once Human.
All you require are a few Advanced Synthesis Workbenches and a ton of Sulphur, which is easy to obtain through Sulphur Nodes that spawn all around the game’s map and in high numbers near the shores of Dayton Wetlands and Energy Links.

Once you have it, you can craft thousands of Acids in one go and have it ready in under eight to nine hours. The low dependency on facilities and the fact that you don’t have to move anything make this method the best acid farm in the game.
That sums up our guide on the best Once Human best Acid farming method.
