Regarding the Aetherquartz Brooch, I've got a real dumb question.
Can you take more than 1 brooch and then roll for each brooch? I'm leaning towards no, but I've been unable to find where it says you can't.
The wording on the brooch says that you receive 1 command point, rather than get that command point back each time you roll a 5+. If my assumption is correct, in theory this could mean getting more than 1 command point each time you Waaagh!
It's especially dirty once you add Prophet into the mix and with GW specifically saying IJ can Waaagh! multiple times.
EDIT - nevermind, found it in the core rules. Would also be nice to have had it duplicated in the artefacts of the realms section
