You can apply various rings to a wand of nothing to turn it into a wand of something related to the ring (e.g. polymorph ring makes a polymorph wand, increase damage becomes striking, see invisible becomes secret door detection, etc). Or instead of the ring identity, make it so that the wand becomes the corresponding material of the ring, e.g. a steel ring will produce a gold wand.

This gives a message, “As you thread the ring onto the [foo wand] it seems to twist in on itself. You now hold a [bar wand] in your hands.”

Possibly it should also work on any cancelled wand, in addition to nothing wands, which are rare and not always identified.

An artifact wand of nothing or wand of cancellation which has no special powers other than that it will absorb curses like Magicbane.

When breaking an identified wand of nothing, give a YAFM: “Predictably, nothing happens.”

Dipping a blank scroll or spellbook into a potion of gain ability turns it into some random scroll or spellbook. The beatitude of the resulting object uses the same formula as magic markers. Could also do this for wands of nothing, which become some random wand, without changing their charge count.
