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.

those aren't needed to fizzle recall, the only thing needed is paralyze spell and scroll, anything else is too fast of a cast and takes no mana. stone scrolls/parafields and fire fields would keep fizzling over and over and it work quite nice in your favor since you have macros to wall of stone on my guild doors and can set them on anyone's doors. All implanting this would do is favor you and your guild :p where as paralyze it self can be used by anyone.
