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.

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

Unavailable Status Effects

Either these status effects are 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).

Resistant Status Effects

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

Unaffected Status Effects

The Bad

The Good


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.
