Hi. I would like to know if there are separate rules regarding fear, insanity and corruption for tech-priests. I am only asking because I have a player who is playing a tech-priest with left-half of his brain replaced by bionics and he says that it has been "Emperor-blessed". Every time, I ask the players to roll for a fear test, he says "Tech-Priest", meaning he's got cybernetics & half-bionic brain (I really didn't know about his half-bionic brain until recently) and is immune to fear. So, from my understanding, he says he's immune to fear, insanity and corruption. Also, he's been replacing body parts with cybernetics & bionic versions. Should I make him roll to see if he gets the replacement (as if buying equipment, armor or weapon)?
I'm actually getting a little annoyed because he keeps on saying "Tech-Priest", whether I get them to roll a fear test or not. The thing is that he knows more about the 40K universe than I do, so every time he power-plays (that's the word), I just have to take his word for it. However, I have my doubts on certain things he says, especially about the fear & insanity issue. I also think that he shouldn't be immune to corruption, just because he has an "Emperor-blessed" half-brain. Do "Emperor-blessed" body parts, artificial or otherwise, exist in 40K?
Any assistance would be appreciated.
Thanks.
Andy
