Demonspawn mutations
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.
Body-Slot Facets
Monstrous demonspawn develop 3 body-slot facets, while others gain 1.

Ignite Blood
Actually consists of three seperate mutations grouped together, the first two of which are indistinguishable from the tier 1 mutation:
Rank 1: Grants conservation for scrolls. Rank 2: Grants Heat Resistance 1. Rank 3: Ignite Blood. Whenever you make enemies bleed (whether by inflicting bleeding or just random splashes of blood from strong blows), it creates clouds of flame.
1. You are very good at protecting items from fire. 2. You are resistant to fire. 3. Your demonic aura causes spilled blood to erupt in flames. |
Icemail
Actually consists of three seperate mutations grouped together, the first two of which are indistinguishable from the tier 1 mutation:
Rank 1: Cold Resistance 1. Rank 2: Grants conservation for potions. Rank 3: Icemail. It grants +10 AC and melts away when you take fire damage or cast Fire Magic, but it regrows over time. Icemail also lets you walk through freezing clouds without losing potions or taking damage.
1. You are resistant to cold. 2. You are very good at protecting items from cold. 3. A meltable icy envelope protects you from harm and freezing clouds. |
Powered by Death
This mutation triggers whenever you kill anything that leaves a corpse. Increases your regeneration rate by 100 (same as the spell) for each corpse within (3 * rank) tiles of you. Duration is (8 * rank) + 2d8 turns (Max: 40). All corpses contributing to this effect will rot slightly faster.
A wave of death washes over you.
1. You can steal the life force of nearby defeated enemies.. |
Mana Shield
The mana shield mutation has three levels. The first gives you innate spirit shield. Level two increases your MP regeneration rate. Level three causes your HP regeneration to instead fuel regeneration of MP when you are at low MP.
1. When hurt, damage is shared between your health and your magic reserves. 2. You regenerate magic rapidly. 3. When low on magic, you restore magic in place of health. |
Demonic Guardian
Summons one or more friendly demons to aid you temporarily. Only occurs when tension is high, and dismisses them when tension drops. Higher mutation levels require higher tension to activate. This mutation will not activate for worshipers of Okawaru.
Rank 1: Tier 5 (White imp, lemure, ufetubus, or iron imp. Rank 2: Tier 3 or 4 (Orange demon, hellwing, or smoke demon). Rank 3: Tier 1 or 2 (Executioner or balrug).
1. A weak demonic guardian rushes to your aid. 2. A demonic guardian rushes to your aid. 3. A powerful demonic guardian rushes to your aid. |

- get a Might effect (25% chance)
- get an Agility effect (25% chance)
1. You sometimes gain a little power by taking damage. 2. You sometimes gain power by taking damage. 3. You are powered by pain. |
Foul Stench
The foul stench tier has three levels. In the first, you gain one rank of the Saprovore mutation. In the other two, you obtain the first and second level of Foul Stench proper.
When adjacent monsters attack you in melee, they have a 33% chance per level to become sick. When monsters land a strong hit, there is also a 20% chance per level you may cause miasma to appear over the monster. This mutation also provides rot resistance, which negates rotting, sickness, and the effects of miasma.
1. You emit a foul stench, and are resistant to rotting and decay. 2. You radiate miasma, and are resistant to rotting and decay. |
Tier 3 Facets
All demonspawn gain one tier 3 facet.
Hurl Hellfire
Actually consists of three seperate mutations grouped together, the first two of which are indistinguishable from the tier 2 mutation:
Rank 1: Grants conservation for scrolls. Rank 2: Heat Resistance 1. Rank 3. Lets you hurl Hellfire as an ability, but it costs 15% of your max HP. Damage is far greater than monster hellfire: it depends on XL, but at XL27 it does 6d28 damage, as compared to 3d15 or 3d20 for monsters. Like monster hellfire, it ignores AC and fire resistance, but not hellfire resistance.
1. You are very good at protecting items from fire. 2. You are resistant to fire. 3. You can hurl blasts of hellfire. |

Augmentation
Each level gives a spell enhancement and slaying bonus that kicks in at high HP. Bonuses are equal to max(0, ceiling(mutlevel*(2*hp - maxhp)/maxhp))*(0.4*spell power + 4 slaying), so you become more powerful at higher levels of HP.

Mana Shield was added in 0.13.
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.
