For the cancellation effects caused by armor, see Magic cancellation.

Cancellation is the term for removing magical charges and blessed/cursed status 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. Some potions can be transformed by dipping things in them, but this is not quite cancellation. Gremlins can also use their intrinsic-stealing attack to cancel other monsters.

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. 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. Breaking a wand of cancellation that has charges will produce the same outcome. 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, unless 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).

The following information pertains to an upcoming version (NetHack 3.7.0). If this version is now released, please verify that it is still accurate, then update the page to incorporate this information.

The ability of zombies and liches to raise corpses is also negated by cancellation.

As of commit fae75f5, cancelling a troll or its corpse will prevent it from reviving.

Abilities not stopped by cancellation

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

In addition to the changes to trolls above, a displacer beast's natural displacement defense is also unaffected by cancellation.


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 by its reflection.

Cancelling items inside a shop will anger the shopkeeper.


It is possible to un-cancel most monsters by stoning them and then casting stone to flesh on their statue, though this does not work on a foocubus or a nymph.[2] Also, some monsters have stoning resistance, and tiny-sized monsters will turn into rocks or meatballs in the process. You can also un-cancel most monsters if they die and leave a corpse by zapping 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!"

This is the same result as for a wand of make invisible and a wand of teleportation, so a wand of cancellation cannot be uniquely identified in this manner.

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.

Cancellation is usually the only way to uncurse a cursed bag of holding without any drawbacks. If it is cursed, its weight is multiplied by 2; so if a player with a well filled blessed bag of holding dies, the bones file may contain a cursed bag of holding with 8 times the weight it had in the previous game. This will probably make it too heavy for you to be able to pick it up and uncurse it, even if you have maximized your carrying capacity and are carrying no other items. You can still loot or tip it, but if you do this, every item in the bag has a 113 chance of vanishing. The best tactic is to pick up anything from the bones pile that can be damaged by cancellation (especially wands, because their beatitude is mostly irrelevant anyway), and cancel the remaining items. The contents of the bag, just like with any other container, will not be cancelled.

If you are wielding a cursed two-handed weapon in Gehennom, you may have problems uncursing it if your scrolls of remove curse and holy water are all stored in containers (which you cannot open), because neither prayer nor spellcasting is possible in that state. If you cannot leave Gehennom without lifting the curse (e.g. because you have no free hands to gain levitation for Juiblex's lair), you may have to resort to dropping everything you can, then cancelling yourself. This will also cancel all the rest of your worn equipment, and so is only recommended in emergencies. (Some players drop potions of holy water in strategic places as a preventive measure.) NetHack 3.6.0 has added the tip command precisely to deal with such emergencies.


Monsters in GruntHack, SLASH'EM, FIQHack, and EvilHack can zap wands of cancellation at the player. Study the wand of cancellation article for more details.


In SLASH'EM, gypsies are cancelled after they gave a wish, and cannot be un-cancelled.

Cancelling a monster by any means also has a chance of cancelling some of its items.
