Unbreathing

Version 0.30: This article may not be up to date for the latest stable release of Crawl.

Unbreathing creatures do not require air to survive. For monsters, these include undead, nonliving, and plant-type enemies. For players, being undead (Ghoul, bloodless Vampire, Mummy), a Gargoyle or Djinni, or certain forms (Ice Form, Statue Form, Lich Form, Tree Form, or Wisp Form) makes you unbreathing.

Unbreathing creatures are immune to engulf and drowning damage (taking 50% damage from Primal Wave). They are also immune to "spore" effects: the sleep of sleepcaps, and the confusion of ballistomycete spores, wandering mushrooms, and players in Fungus Form.

History

• Prior to 0.27, unbreathing gave explicit immunity to curare's damage (but not the poison/slow), Mephitic Cloud, poison clouds, and miasma/Sickness. Note that most unbreathing monsters were already immune to these effects, due to their holiness. Also, grey Draconians had unbreathing. (In 0.27, they gained amphibiousness, which allows them to resist drowning).
• Prior to 0.26, unbreathing creatures were not immune to miasma.
