Icon Potion of cancellation.png
A potion which ends most magical effects, good or bad, affecting one who drinks it. It also reduces magical contamination.

Quaffing a potion of cancellation immediately ends nearly all status effects you may be enjoying/suffering from. It also removes 1000-5000 points of magic contamination. The potion's description lists all your current status effects that can be removed by the potion.

Affected Status Effects

These are also the effects that can be ended from Quicksilver Bolt (including the wand of quicksilver) and Yara's Violent Unravelling. The list of all affected status effects is as follows:[1]

The Bad

The Good

Resistant Status Effects

Rather than being dispelled outright, these status effects will have their duration set to 1 turn.

Unavailable Status Effects

These statuses can be cancelled normally, but are either exclusive to monsters, or a player wouldn't be able to act while in the status (where a monster's Quicksilver Bolt can end it).

Unaffected Status Effects

The Bad

The Good

Strategy

Cancellation is incredibly useful for removing a variety of detrimental status effects. Some of the more important statuses include Petrify, Mark from an alarm trap, and bad forms. While it will also remove contamination, using it simply for this purpose is often less useful than for emergency status removal, especially considering that these potions are on the rarer side.

It'll also remove some of the more useful statuses like Haste and Tele, so be careful! This makes enemies with Quicksilver Bolt some of the more threatening monsters in the game.

The following statuses may be ended via other sources:

History

  • The list of the cancellable effects was added to the potion's description in 0.27.
  • Potions of cancellation were added in 0.15, partially taking the role of scrolls of vulnerability.
