Create food is great! Every religion has their own interesting (and some kinda disturbing) special foods, it's fun and great.
Why not with create water? Why can't the Mirans make some weird juice to go with their beans? Or when you look into a priest of Death's container it's full of stale water or something? Mead for Sargas, a Nectar of Truth for Dulrik... and so on...
I'm not too interested in what each religion would pick for their drink, that would have to be up to those in the religion and to be debated in their respective private forums.
The big question is could this ever happen (imms?), and do you think it's a good idea?
I know I'd like to see "A barrel filled with liquid rainbows." or whatever weird stuff could be thought up for some of the more 'fun' religions, among others.
