Version 0.13: 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 facet
- They gain one tier 3 facets
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.

Prior to 0.12, Augmentation kicked in at low HP instead of high HP.

Prior to 0.11, magic resistance was available as a Tier 2 facet.
