Also, the effects apparently increase the more scrolls that are used at once. I'm not sure what the progression is, but the impression I have is that it is not linear. Tom certainly made it sound like they have the potential to go nuclear. From what I can recall reading in the thread where he introduced them, there was a certain expectation that realms might start hording them in a sort of arms race. Personally I can't wait for someone to use a whole bunch of them at once, just to see what happens. OOC of course. My character would be horrified at the thought.
