Cancellation is the term for removing magic from an object or disabling the special attack of a monster. The most common source of cancellation is the wand of cancellation. A few are able to use the spellbook of cancellation. Magicbane can sometimes cancel things it hits. Foocubi can spontaneously become cancelled.

Cancellation of objects

Cancellation has the following effects on objects:


"In short, cancellation is quite thorough."

Except for certain scrolls, spellbooks, and potions, cancelled objects do not change type. Cancelling a bag of holding or magic lamp will merely uncurse it, not turn it into a sack or oil lamp. Cancelling an artifact will not turn it into a non-artifact. Cancellation has no effect on the objects inside a container.

Cancelled wands end up with (x:-1) charges, where x is its value prior to being cancelled. Cancelled wands can be recharged subject to normal restrictions on wand charging, but cannot be wrested; if they are zapped or engraved with, they will turn to dust.

Irina Rempt has written an excellent and thorough spoiler on cancelling objects. Consult it for more details.

Cancelling yourself

If you zap a wand of cancellation at yourself, every item in your inventory (except the wand itself) will become cancelled. All equipment will revert to uncursed and +0, all spellbooks and scrolls will turn blank, etc. This affects only items, i. e. the naked player monster is not cancelled. Do not do this with a wand that you think is a wand of make invisible. Self-cancellation is one means of removing cursed gear; just be sure to drop or bag everything else before zapping. Polymorphed players revert, except if unchanging.[1]

A corner case: You are immune to cancellation if you have magic resistance, unless you are zapping yourself. Monsters cannot zap cancellation in Vanilla, so this matters only for the point of maximum power you lose when hit by Magicbane (and unpolymorphing).

Cancellation of monsters

Monsters have an opportunity to resist cancellation effects. If the monster fails, it is cancelled and loses most of its special abilities.

Abilities stopped by cancellation

The following attacks and special abilities are entirely stopped by cancellation:

Cancelling clay golems causes them to be destroyed immediately (this is because they, according to legend, are animated by an inscription on their forehead, which the wand erases).

Abilities not stopped by cancellation

Some attacks which are not magical in nature cannot be cancelled, these include:

Notes

Cancelling a cockatrice or chickatrice prevents it from stiffening you with its hissing, but direct physical contact with it or its corpse can still cause stoning.

Cancelling Medusa removes her stoning gaze, which also means that she cannot be stoned with a reflecting item. Similarly, cancelling a floating eye means it cannot be paralyzed with the same.

Un-cancelling

It is possible to un-cancel most monsters by stoning them and then casting stone to flesh on their statue. This does not work on a foocubus or a nymph, though (zap.c, line 511). Also, some monsters resist stoning, and tiny-sized monsters can turn into rocks or meatballs in the process. You can also un-cancel most monsters if they die and leave a corpse. Zap the corpse with a wand of undead turning - it will come back to life uncancelled.

Cancelling the floor

Engraving on the floor or zapping downwards with a wand of cancellation will cause any previously created engraving on the floor space to disappear.

"The engraving on the <floor> vanishes!"

Considering when to cancel

Suppose you need some blank scrolls and spellbooks and some potions of water, because you plan to use your magic marker and make holy water. If you have a wand of cancellation, one strategy is to put all your junk scrolls, spellbooks, and potions into one pile, then zap it with only one charge. However, it is usually easier to wet those kinds of items rather than cancelling them. The advantage of cancelling in the early game is that you do not need to use fountains, which are sometimes rare, and can cause nasty side effects. Once you find a pool or moat, or break a fountain to make a pool, you can save cancellation for use against monsters.

A few items can be rendered useful by cancelling them: a perfectly useless cursed -5 pair of levitation boots, for example, will cancel to a perfectly good uncursed +0 pair.
