That's fair and reasonable.  I half expected to lose a turn and go flat-footed or something for the form change, so putting it off until things chill out is A-OK in my book.  As for the Marquis folding up, I wouldn't worry about it too much, there's still<em>plenty</em>of blood curdling danger in this room.<br/><br/>Web is definitely a good spell though, for sure.  Just, ya know, you can't cast it in an open field, it needs something to "hang" from.  Since most dungeons are indoors this rarely comes up, but it caught me out once when I was fresh from CG D&D back to tabletop.
