I noticed that there are no rules for force weapons but they are mentioned a few times in the book. I was wondering if there existed rules for these perhapes in dark heresy. I looked at the 40K rules to see if there were any obviouse translations, but killing enemies with a single hit regardless of wounds seemed a little excessive.
I want to have an astro path use a force weapon since there is a psychic background for both. I was thinking the weapon could work like psy focus or reduce rolls on perils of the warp (or something).
As far as a damage profile I'm a little at a loss. I guess they could count just as power weapons but I'd like to incorporate some psychic abilities. Like maybe the player can make a focus test before and add thier psy ratting to the pen or damage. Of course I don't want it ot be too overpowered (although force weapons are supposed to be pretty epic), I just want a cool weapon for astro paths.
