So, considering that this Adventure Path mainly takes place in sub-zero temperatures, what happens if someone decides to cast Create Water? I figure if they cast it into a closed container then it's (probably) all good, at least until it gradually cools - but can my PC's use it to coat things in ice or build ice barriers or cause hail or snow or ... ?
I'd generally default to "a spell can never duplicate the effects of a higher-level spell", but then again ... physics. If I was in sub-zero temperatures and could suddenly produce gallons of water wherever I'd like, I'd expect it to freeze, and I'd expect that frozen water to have *some* effect.
