Hello fellow renegades!
I got to thinking about the specifics of Fear. A study of the rulebook and a quick search of these forums did not yield a definitive answer to this question: does Fear generated (by a mutation, etc.) by a Heretic have an effect on other Heretics? Since potentially all Heretics could have a Fear rating, and since I didn't spot any mention of having a Fear rating generating any degree of immunity to Fear effects, a gathering of peers could lead to silliness of the extreme quality.
I have a feeling I've simply missed the part where this was discussed. Posting here to see if that is the case, and if not, what the collective take on this is.
