My hope was that I’d be able to get Pal fluid more peaceably, perhaps by extracting it painlessly from one of the creatures in my care, although now I say it out loud, I’m not sure that sounds any less disturbing. Sadly, it appears you can’t milk Pengullets or Teafants for their juices, so I had to jog down the path and club one to death for the final fluid I needed.

It’s not Rimworld, but it feels in the same galaxy.

P.S. Some interesting unlocks coming on my next level-up:

P.P.S. Did I mention Pal Spheres work on human opponents too?

P.P.P.S. Yes. The answer is yes.
