Version 0.30: 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).

Transmutations can cause the following changes, depending on the form:

  • Modify Unarmed Combat
  • Have innate properties, like bonus HP, AC, stats, or resistances.
  • Have a different size or movement speed to your base form
  • Meld certain types of equipment. 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.

All transformations will also make you vulnerable to silver weaponry (+75% damage from silver weapons)

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.
