Wand of cancellation
From Wikihack
A wand of cancellation can be used to:
- change most potions into water (but fruit juice, booze and oil are not changed, and see invisible and sickness become fruit juice).
- change scrolls into blank scrolls
- neutralize monsters by taking away their special attacks
- neutralize negative and positive enchantments of weapons and armor
- uncurse and unbless items
- erase engravings
The wand of cancellation has a number of complicated effects; when you find one, it will behoove you to study thoroughly the article on cancellation before zapping it!
Do not zap yourself with an unidentified wand that makes engravings disappear; if it is a wand of cancellation, you will lose all your scrolls, spellbooks, and potions; these will become blank scrolls or water.
Putting a charged wand of cancellation into a bag of holding will cause a magical explosion that will destroy the bag and everything within it. Don't do this. Zapping a bag of holding, however, will either unbless or uncurse it, and will have no effect whatsoever on the contents.
Zapping a wand of cancellation at a clay golem will erase some writing on its head, killing it instantly.
If you have a pet without a special attack (such as a kitten), you can zap an unidentified wand that makes engravings disappear. If the pet disappears, it is either Teleportation (and you can find the pet later in the level) or Invisibility (which you can see if you have the See Invisible intrinsic). To confirm, you can use a Stethoscope, the information line from it will say that it has been Cancelled.
Among other special attacks, Magicbane has a cancellation attack, which is similar to zapping something with a wand of cancellation.
