A pointless argument between myself and another player... can you jam while checking for Righeous Fury? Of so, what happens?

I'm of the opinion that you can't, as its not a seperate attack, where as my compatriot thinks not only can you, but it also voids the attack you just made.

I would agree with you gradea, the roll to confirm Righteous Fury is just that and not a separate attack that can result in a weapon jam.

It is stated to be WS Test to confirm the Righteous Fury...so no Jamming...

The attack itself has already landed, there's no screwing it up at the point. The fury roll is to see if your attack pulled off that super special bad touch that makes the target's insides think that it might be nice to go for a walk outside.

I agree with you there. After all, you can't jam/overheat/whatever a weapon while unjamming it (another BS test) either.
