Version 0.29: This article is up to date for the latest stable release of Dungeon Crawl Stone Soup.

Transformations are effects that completely alter the form of a creature's body. While many of them are caused by Transmutations spells, a few of them have other sources.

Useful Info

Transformations are always temporary. Whenever they can be cancelled at will depends on the transformation itself and its source, but all transformations are stopped by a potion of cancellation and Quicksilver Bolt (the latter leaves 1 turn left on the duration). All transformations also make you vulnerable to silver weaponry, taking up to +75% more damage from them.

Most transformations meld equipment, dependent on the form. Melded equipment ceases to have any effect, positive or negative. Melded items are not unequipped, rendering you safe from an artefact's Drain and Contam. Each form will also negate certain mutations. To compensate, transformations frequently alter a character's Unarmed Combat and may change a number of other properties: HP, movement speed, size (and therefore EV), AC, resistances, among others.

Undead creatures cannot be transformed. For players, this means that Ghouls and Mummies can never be transformed, while Vampires can only be transformed when Alive. Lich Form renders you immune to other transformations, but you can still extend it by casting Necromutation again.
