Whats the best place to farm Acid?

[DeadlyKitten]

I know it drops from zombies, and i'm level 30 now.
Is there a concentrated place where it drops in high amounts from kills?

Use food for 50% buff or farm it with waterpump in special areas.

If you have enough Power in your base you could build the Acid farm from youtube. This Farm can produce over 1000 acid passive per day.

Refinery farming on teams with deviated ribs works for me Solo can work with enough cards and the silo PHI so long as you dont break the nests its infinite farming and better with ribs Take every crisis event that has deviants and form teams with the players all while using the ribs buff Im sure others have better places tho ;-;

the amount you get from mobs is always the same, just go to cities and kill em all, if u are lucky enough to have the food that buffs it, use it as well.

refinery(if u got permits or others use theirs) is also a pretty good way but limited due to permits needed.
