Reshape Reality. You may wish for something not included in any of the other effects. To do so, state your wish to the DM as precisely as possible. The DM has great latitude in ruling what occurs in such an instance; the greater the wish, the greater the likelihood that something goes wrong. This spell might simply fail, the effect you desire might be achieved only in part, or you might suffer an unforeseen consequence as a result of how you worded the wish.

DM says no.

If your wish would affect a god, the god’s divine servants might instantly intervene to prevent it or to encourage you to craft the wish in a particular way.

God says no.

If your wish would undo the multiverse itself, threaten the City of Sigil, or affect the Lady of Pain in any way, you see an image of her in your mind for a moment; she shakes her head, and your wish fails.

Reality says no.
