I tried to spawn them as thralls in single player by used admin.
They have 10k Hp and I was like… wow , so I head back to the Official server and build thralls taker station fast.
But after I go to try in Official server , I can’t knock them.
I would say no. I tried with a T4 fighter wearing Legion armor, both of us had improved steel truncheons, we worked on him for awhile, but he didn’t lose any HPs at all. I had to eventually kill him to save my thrall.
I had a similar experience, although my thrall was wielding a real weapon while I was using an augmented steel truncheon. The Boss relic hunter didn’t seem to lose any “KO hitpoints” so we had to murderize her.
