I'd like to know some methods of curtailing the abuse of the Illusion wizard's Illusory Reality feature in a game.
Right now I have a player here running roughshod over the other GMs in the group by using it to pull off some highly destructive and, IMHO, questionable tactics. Things like making part of a castle floor seem to disappear, then making it real, dropping half a dozen soldiers to the next floor down; cue falling damage. He's even gone so far as to have objects crush high-level victims upon the object's return from the illusory state.
He generally has some impressive logic to back him up, but I get the feeling, watching him work that he's generally violating both rules-as-written (RAW) and rules-as-intended (RAI) on a regular basis.
He, admittedly, hasn't done this to me yet, but I run 3.5E and Pathfinder normally, which has its own potential for rule abuse.
