To be fair Gravislayer makes a good point, your post was a bit OP, but as long as Infin1te doesn't do it again, than we shouldn't argue over it, and have fun. I know both of you will have your opinion's on whether or not it is OP, but I don't think that he did anything important enough for him to change his post, unless that GM's disagree, but I don't think you should be able to put an entire guild of B, and A class mages under an illusion spell without serious preparation, or being extremely exhausted after words...It just gives you to much of an advantage especially if you used it in lets say combat, and you were in the same circumstances against an enemy of 20 mages just as high level as the guild (varying from B, to A level, and a Master level mage), but it is only a minute. Well in that minute you could probably kill of 15 of the 20 mages, and still hold ground with the rest, because your not even exhausted. That is overwhelmingly powerful, while the rest of the wizards if they were put in the same position might defeat a few, but would be defeated with ease. I hope you understand :)
It doesn't warrant change, but it would be very exhausting to put an entire guild under an illusion. Also there isn't really a reason to do so(to your own guild), unless you want to piss off everyone in the guild when they find out what you've done.
