In good ol' times cancellation was just a game concept

Wand of cancellation

A wand of cancellation emits a beam which cancels any monsters or objects it hits. Monsters are entitled to a resistance check against the effect.

Putting a charged wand of cancellation (or a bag containing a wand of cancellation) into a bag of holding will cause a magical explosion that will destroy the bag and everything in it. Zapping a bag of holding, however, will either unbless or uncurse it, and will have no effect on the contents.

Effects

The wand of cancellation has a number of complicated effects. Among these effects, it will:

• uncurse and unbless items
• neutralize enchantments and charges of most items
• change most potions into water; sickness and see invisible into fruit juice; booze and oil just become uncursed
• blank scrolls and spellbooks
• neutralize the special attacks of many monsters
• kill a clay golem instantly by erasing its writing

Applying a wand of cancellation will break it and cause a damaging magical explosion that also cancels all monsters and objects in a 3x3 square around you. See breaking wands for details.
