with the new spells being able to be taken by any wizard I feel like it makes more sense to definitely bring a starpriest or possibly 2? Is the rule of one consistent for multiple units? If for example I wanted to run a slann with GR and 2 starpriest with tempest to be anti horde. Would turning them into nuclear bombs be viable? Or would I only be able to have one of them have tempest. The idea being get them into range either through movement or port if necessary and then Cast tempest. With a 24” range and needing the unit not the model count it feels like a decent way to get 30-60 rolls off and really do some damage in the hero phase. Thinking that, would we be able to bring 2 and do that again or only one?
