Books at home and I'm at work... but I was thinking about this.
The scenario I'm thinking of is
1. Does doom work against vehicles. Classically we wound people and damage vehicles, but I can't seem to recall if 4th edition states there's a difference anymore.
2. If Doom does work and a unit of harlequins attack a mutated defiler. What gets rerolled. The first part of the damage the 1/6 chance they get the 6 to rend or just the 2nd d6 on a successful rend or both parts?
I would think that if doom works against vehicles then.... you'd have the option to reroll either or both aspects of the damage roll.
thoughts?
