In this guide I will attempt to briefly explain the way to setup a “non-maintenance” bioferrite farm I discovered on accident.
RimWorld How to setup a non-maintenance Bioferrite Farm
Basic Setup
Build the “Freezer” (Holding platform surrounded by coolers).
Capture “Toughspike” (Fleshbeasts summoning ritual or the Pit event).
Transfer the entity to the “Freezer”.
Wait until they heal up all the damage before proceeding (they tend to die during freezing otherwise)
Set the target temperature to -99 and wait for the hypothermia to build up to ~60%, once you reach it crank the temperature down to -49.
TGhis will keep the hypothermia steady, it will neither decrease or increase.
Wait for frostbite to take out left/right tentacle and remove their ability to move.
Now just transfer them back to your containment room and they will never escape again!
Extra Info
You don’t need to take out their arms only legs, I just prefer to have them look the same for aesthetic reasons.
Electroharvesters might actually kill your entities over a long period of time by damaging the brain.
