Revision as of 19:29, 18 September 2017

Version 0.20: This article may not be up to date for the latest stable release of Crawl.

As demonspawn characters level up, they gain useful mutations due to their demonic ancestry. Demonspawn mutations are semi-random, according to the following rules. A 'facet' is a set of three levels in one mutation:

  • 90% of the time, they mutate as follows:
    • They gain one body-slot facet
    • They gain one scales facet
    • They gain two tier 2 facets
    • They gain one tier 3 facet
  • 10% of the time, they are "monstrous", and instead mutate as follows:
    • They gain three body-slot facets (claws, horns or antennae, hooves or talons)
    • They have no scales facets
    • They gain two tier 2 facets
    • They gain one tier 3 facet

Monstrous demonspawn are far more offensive-minded: they have lower AC due to their inability to wear any armour other than cloaks, shields, and body armour, but their claws make them well-suited to Unarmed Combat. Your auxiliary attacks also support close combat.

Here is a list of all possible demonspawn mutations. Note that many of these mutations can also be gained randomly. However, demonspawn mutations are unique in that they cannot be removed by any means. You can check your current mutations with shift-A.

Body-Slot Facets

Monstrous demonspawn develop 3 body-slot facets, while others gain 1.

Claws

Rank Effect Flavor
1 +2 unarmed base damage. Negated by gloves. You have sharp fingernails.
2 +4 unarmed base damage. Negated by gloves. You have very sharp fingernails.
3 +6 unarmed base damage. Prohibits gloves. You have claws for hands.

Using Unarmed Combat with level 3 Claws will decapitate hydra heads.

Species notes: Ghouls start with rank 1 and Trolls start with rank 3.
Octopodes cannot gain claws.

Damage: 5 + (3 * rank)
Chance: 66% * (30 + XL)/59 per melee attack
Minotaurs may retaliate against enemies with headbutts.

Species notes: Minotaurs start with rank 2, and Oni start with rank 1. Demonspawn can gain horns as a body slot option. Octopodes cannot gain horns.

Good mutation, Demonspawn mutation


Antennae

Rank Effect Flavor
1 Shows the location of all invisible enemies in line of sight. Detects all monsters within 3 tiles, even through walls or opaque clouds. Prohibits helmets. You have a pair of small antennae on your head.
2 Range increases to 5 tiles. Prohibits helmets. You have a pair of antennae on your head.
3 Range increases to 7 tiles. Grants see invisible. Prohibits all headgear. You have a pair of large antennae on your head.

When playing in console mode, creatures not in line of sight are revealed as { or { glyphs, depending on whether the entity is hostile or friendly. In tile mode, they appear as icons which similarly indicate hostility. Mimics will be identified as soon as they enter your antennae range.

Species notes: Formicids start with rank 3. Demonspawn can gain antennae as a body slot option.

Good mutation, Demonspawn mutation
