Notably, it does ''not'' affect [[Death's Door]], lowered MR, [[Thunderdome#Quad damage|Quad Damage]], [[Tornado]], [[Infusion]], [[Song of Slaying]], the Elixir Card, [[Dragon's Call]], [[Aura of Abjuration]], or [[Powered By Death]]. It also ignores poison and liquid flames, berserk, sleeping, and fortitude, and god-specific effects. It has no effect on stat drain. It will remove the slow status caused by miasma and curare, but it will have no effect on the other ailments caused (rotted HP and poison in case of miasma, asphyxiation and poison in the case of curare).

Confusion can be removed with the far more common [[potion of curing]], which lets one save potions of cancellation for more obscure, but no less dangerous, status effects, such as petrification, slow, and Sentinel's Mark. Its ability to cancel Mark makes it particularly useful for Vaults, especially on a character that has had poor luck in finding gear that increases resistance to magic. Finally, if you find yourself with dangerous levels of contamination, one or two of these potions may bring you back to safe levels while avoiding the usual bad effects. However, unless there are many cancellation potions on hand, one should be wary of using cancellation potions simply for the purpose of glow removal outside of combat, as getting hit with an ill-timed Mark or Slow tends to be more dangerous than suffering one or two contamination effects with no monsters around.

The same cancellation effect occurs when you are hit by a Quicksilver Bolt or sometimes by Sif Muna's punishment.

Strategy

Confusion can be removed with the far more common potion of curing, which lets one save potions of cancellation for more obscure, but no less dangerous, status effects, such as petrification, slow, and Sentinel's Mark. Its ability to cancel Mark makes it particularly useful in the Vaults, especially for a character with poor magic resistance. Finally, if you find yourself with dangerous levels of contamination, one or two of these potions may bring you back to safe levels while avoiding the usual bad effects. However, unless there are many cancellation potions on hand, one should be wary of using cancellation potions simply for the purpose of glow removal outside of combat, as getting hit with an ill-timed Mark or Slow tends to be more dangerous than suffering one or two contamination effects with no monsters around, particularly if you have several potions of cure mutation lying around.

History

Potions of cancellation were added in 0.15, partially taking the role of scrolls of vulnerability.
