So what powers offensively can pariash do? Can they use their void powers to make things explode, or disolve, whatabout invisibility, or a void black hole (trying to think of things)?
And what about the black pariah in nemesis? Did he show any powers that he could use to harm non psykers? Tk or anything? And if he was so powerful what happened to him?
It differs with each individual but it's not an overtly offensive power but just something that they're born with, of course certain technologies allow them to project this aura (i.e. Culuxes Assassins).
In a way they're invisible, to psykers at least they'd appear as an uncomfortably vacant space (it's size dependent on the individual once more) but that in itself could allow a psyker to find them. When everything seems to be normal then it's logical that your Pariah quarry is situated in the only place you can't see. Of course even psykers can detect them with their 'natural' senses.
Oh they also create a sense of unease amongst non-psykers, so much so that they're often victimised because their very presence is antagonistic to other humans (though supposedly not to other blanks).
@Baron Spikey Well I remember reading A THOUSAND SONS (possible spoiler alert!!!!!!!) and it seems that the entire sisters of battle/silence nagate the powers of the sorcerors. Is there another way ov obtaning this ability because it seemeed like ALL ov them had this gift.
It's a genetic trait, the Sisters of Silence aspirants were chosen because they had tha genetic quirk rather than being chosen and somehow given the ability (which as far as I know is an impossibility).
Edit: oh and supposedly the Necrons, or at least their C'tan masters, introduced this genetic anomaly into humanity (or at least mankind's very, very distant ancestors) so that one day when they awoke they could harvest those individuals who possessed the gene to combat the power of the warp.
