In Dark Heresy, a successful Righteous Fury resulted in an extra d10 being rolled and added to the damage.
In Rogue Trader, a successful Righteous Fury rolls adds a whole new damage roll on. I thought this strange at first, but then the example of RF given in the rulebook shows that a laspistol that benefitted from RF would add d10+2, not just d10.
How does this work with weapons that do multiple dice of damage? With an increased chance of getting further results of 10 on each die, the damage will go through the roof! Is RT really meant to be this much more lethal than DH?
