#3: This isn't screwing around. The sorceress (and in turn the player of the sorceress) should know what the spell description of Wish says. She should also know that she is essentially asking for 3 wishes in 1.
I meant "screwing around" in the sense that there will be some dangerous and semi-arbitrary consequences; a poor choice of words on my part. Something like "Well, just before you repeat the incantation, you suddenly remember Kezzeldrix the Unpleasant, who used a similarly mighty dweomer to save his allies from a red dragon's breath. They say he was dragged to Mechanus and never seen again. You doubt that
always happens. Probably. But you might want to keep an eye out for a few months, at least."
Honestly, though, I consider the "safe" wishes to be very safe indeed, with absolutely no negative repercussions conceivable. Something like this I see as only very mildly risky, like entailing a 1% chance that you attract the attention of a Marut Inevitable. It's a reasonable use of a 9th level spell and a boat-load of XP, so I would have some kind of token risk and let it go.
That said, I think I was being too testy. (Previous posters were getting my gourd up.) Depending on the campaign situation, I think the inevitable idea would be interesting, and I'd move that to my #2 slot. Maybe roll a 25% chance and just see what comes up and run with it.
I also have enough rapport with my players that if they started using
wish as a reset button every time they had problems (highly unlikely in any case) that I wouldn't have a problem (personally, or from their side of the screen) screwing them over the third tiime they tried it, or whatever. I also don't feel antagonistic enough towards them to carefully avoid giving them any inches, for fear of losing miles.
Dang it, one more edit: There's also the unselfish angle. It's a point in favor of granting the
wish without hurting the players that doing so encourages something I want to encourage as DM - the players being nice to each other and building strong intraparty bonds. I personally would also enjoy the potential RP of the three dead guys recognizing the sorceress's act of generosity.
