I think that Cloud Trapeze should not work from/to cave provinces. I am
playing a game with tons of caves, right now, and I feel weird trapezing
back and forth. I also have to keep telling myself that I am not safe
from spells like Flames from the Sky, Huricane, etc...

I agree that it would be nice if there were a set of spells that didn't work inside of caves-and a separate set that only did, or worked better-maybe better than you want them to, like Earthquake, for example.
Earth elementals should be stronger inside of caves too.

Perhaps caves should get some kind of PD boost or something to represent the ease of defence. Lots of narrow passages and such is much easier to defend than a wide open field. At least I would imagine so; I've never actually _personally_ fought inside of a cave, nor a wide open field for that matter.
