My game is set in Seattle, and the players have a couple city aspects to deal with- It never rains but it pours (things tend to stack up on them- no small problems), and Here comes the rain again...
In seattle, IRL, it rains a lot, but not constantly. It's more like very frequent showers year round. It can be clear one minute, drizzling the next, or monsoon the next after that, then clear again an hour later.
Certainly causes problems for mages. I let my players compel that city aspect for a fate point at any time, but given that one of them is a mage, they really haven't yet. I've compelled it once as GM, and the fate point went to the mage, as they were the only ones to really suffer as a result.
My question is 2-fold... one, if there are mages on both sides of a combat, should anyone get that fate point, and if I have more than one mage in the group, should it go to whoever's worse off or both, or to a group pool?
two, what's the best way to run this? The one time I've done it, I set it up as a universal Block 2 against magic (3 against fire magic) and magical beings/ecto, for a light shower- more if it were a heavy downpour or outright monsoon season... but I'm wondering if it wouldn't be more appropriate to do it as universal armor, since armor survives what bypasses it, and rain would be more likely to make a spell harder to fuel (reducing it's overall power) than hard to control.
