Ok the description is quite simple - you don't suffer the effects of Fear and Pinning, and you have difficulties disengaging or backing down from a fight. But what does that actually entail?
Interpretations:
1. You are immune to the effects of the Shock table and the effects of Pinning. You still take insanity points and corruption as normal (unless you are Jaded).
2. You are immune to all possible effects of Fear, including Insanity points. Unless you get insanity points from some scource which is in no way related to fear and horror, you will never take IPs again. You can get Corruption points, but not from witnessing warp-creatures, demons and other fear-related scources. NOTHING will unerve you or disgust you, your mind is essentially immune to trauma. There is only War.
3. You are immune to straight up fear, thinks and situations that are scary for some reason. Full blown galactic horror, such as gazing into the warp, experiencing a full-blown deminic incursion, seeing certain extremely horrible beings, and personal horror with great emmotional shock can still cause IPs. In other words, Horror does not equal Fear in this case.
So which of these interpretations do you agree with? Which one would you personally like best? And which one is RAW?
IMHO I think no matter which you choose the Fearless talent is worth it despite the drawback, but #2 is definetely the most powerful.
I just can't seem to pull myself away from the computer right now... Just one more click...
) in making sure the details are correct. Or do a quick search of the forums for the posts with the discrepancy that I encountered while compiling the data for those sheets to try and get a 4.0 errata out (which still hasn't come in over a year). Hardly the type who is going to lie about a response about a rules question asked.
