OK guys, last night final trans was cast on the witch elf unit with cauldron inside. Obviously the character takes a roll on a 6, but, do I have to roll for the cauldron as well? Or is it one roll for both, or do not even roll for the cauldron?! (I rolled a 6!!!)

Thanks guys

bump!

The DH, the COB and its attendants make together a single model.
Final Transmutation affects models. One single roll for the whole model.
Everything was therefore turned as gold, and is removed as a casualty.

Aye, sounds about right to me. One roll for both, which are turned to gold on a 6.

I disagree. I would think you roll separately for the rider and the mount, seeing as how with a normal direct damage spell you would have to allocate hits. So the death hag is hit, and affected on 6, and the cauldron is also hit and affected on a 6.

Final Transmutation states that you roll a D6 for every model in the unit.

Elsewhere in the BRB, it's made clear that a monster and rider (or in this case, a chariot and its rider) is one model, but with two components. This is why a cannon or template weapon hits both the monster and the rider, but why you randomise hits from BS shooting attacks against either the rider or the mount. It's why you can Killing Blow a monster's rider separately from the mount itself, and why Heroic Killing Blows on the mount won't kill the rider.

I understand your point, Thraundil, but there are no hits to be allocated here. Every model in a unit takes the relevant test when Final Transmutation hits the unit, not every part of every model which can be separately targeted (which, admittedly, only comes up in the case of characters riding a chariot or monster).

Returning to the question at hand: the spell uses the word "model". A Cauldron of Blood with a Death Hag on top is one model. If it's targeted by Final Transmutation, you roll once, and hope it's not a 6. If it is a 6, you take the whole thing off.

OK thanks guys!!!
