I also support taking damage being a revealing action and am kind of surprised that things didn't already work this way.

I'm not sure this is necessary, not saying it's a bad thing or that it shouldn't be changed to work like this.
All that needs to be done, in my opinion, is make walls fire fields and para fields fizzle someones recall if you land it on someone while they are invis. It would be nice if it revealed them too, but honestly I think that is a bit too much. If you can fizzle their recall indefinitely with fire field scrolls, they'd better move because you cast about 6 firefields on their tile they are going to start taking pretty good damage.
