Attacking Helpless Targets/Righteous Fury

By bogi_khaosa, in Dark Heresy Rules Questions

This is coming up in my current game.

If you roll a 10 on damage, you test against WS to see if you get Righteous Fury. My question is this:

Is this test made using the attacker's unmodified WS, or with all the modifiers of the original attack for range, aiming, etc.? I am especially concerned here because when attacking helpless targets your attacks always hit, implying a 100% chance of getting RF in this situation any time you get a 10. What do you guys think? Thanks!

I believe it states in the book the rules for righteous fury on helpless targets. Check under helpless targets in the book.
