Meh... Cant be bothered to read all posts...
Fear is a very powerful trait. And Psuedo-Daemonhood is just meh, so you look like a Bloodletter which is Fear 2... But due to the wonky Gift you are as scary as a Bloodthirster. Makes perfect sense, not.
In my group we made Psuedo-Daemonhood Fear 2, but added Daemonic 2 to it instead. Which yes, would make said character count as a daemon in every possible way, an inferior one in some ways though.
Also houseruled it so oft encountered sources of Fear stops being so terrifying. And Fear 1 stuff shouldnt bother a heretic anyway, so no rolls at all for Fear 1. If you live in the Vortex, those slightly scary things are not that scary compared to what you see every day.
And if you are bothered with those houserules. First step, get Jaded. That talent makes it so that only warp-horrors and potentially uber scary xenos bother your sensibilities, you know like 'nids, And it is only tier 1, and lots of archtypes even starts with it. Second, get Resistance(Fear)... Also a tier 1 talent. Invest in WP, something I tell people in every 40k RPG. Granted one of my DH players cant make a Fear check no matter how much WP his character happen to have.
Or just make your own Gift when you get one and give yourself From Beyond trait. The ones in the core book are horribly boring anyway, especially when compared to what was in Tome of Corruption for WFRP2. Not to mention how few there are, and how useless most of them are. Basically the only good ones are "Eye of Chaos", "Wreathed in Chaos", "Mechanoid" and the ones that give Fear, and maybe "Wings".
