Get Strong Acid when a key recipe, tool, or machine is blocking progress.

Strong Acid matters because it sits inside a larger craft chain. The useful question is not whether the item exists, but what ingredients feed into it and what build opens up once you have it.

Why it becomes urgent

Players usually look up Strong Acid when a blueprint, machine, or tool path stops moving without it. The best route is to gather the full chain in one run instead of crafting reactively piece by piece.
