Strategy
Cancellation is incredibly useful for removing a variety of deterimental 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:
- Confusion - quaffing a potion of curing
- Teleport - reading a scroll of teleportation
- Slow - negated by haste
History
