Succubus system 1.4.8

About This File

Succubus System

Succubus System is a dark-fantasy gameplay expansion centered around demonic transformation, supernatural progression, occult magic, corruption, relationships, prostitution, slavery, infernal armies, and the struggle between demonic and holy powers.

Characters can enter a demonic path, develop unique progression tracks, use Absorption and magical rituals to gain power, build demonic infrastructure, manipulate other characters, host special activities, and eventually become immortal Succubi or Demons.

The mod is designed around long-term character progression rather than simply granting an overpowered trait immediately. Lesser demons must develop their abilities, acquire resources, interact with other characters, and decide how much of their own power they are willing to spend.

Demon Progression

There are two normal demonic progression paths:

• Female: Lesser Succubus → Succubus
• Male: Lesser Demon → Demon

Succubus and Demon are the normal final forms. Both are truly immortal and no longer die from old age.

Lesser forms are not fully immortal, but their progression tracks provide significant lifespan increases and gradually unlock stronger supernatural abilities.

True Demons

A separate True Demon tier represents the ancient infernal beings:

• Lilith
• Abaddon
• Beelzebub
• Mammon

True Demons are not part of the normal Lesser Demon → Demon progression path.

They are ancient supernatural entities with extreme power, true immortality, greatly enhanced attributes, and the ability to perform demonic magic without depending on mortal infrastructure.

True Demons also play an important role in spreading demonic corruption by transforming mortals into Lesser Succubi or Lesser Demons.

 

How to Become a Demon

In normal gameplay, a mortal character can enter the demonic path through a True Demon.

A True Demon may choose to transform another character, or a mortal may directly ask a True Demon for transformation.

The agreement can involve several conditions, including:

• Gold
• Hooks
• Favors
• Religious conversion
• Personal relationships
• Character rank and ability
• AI personality and opinion

Characters must be at least 16 years old.

Female characters become Lesser Succubi, while male characters become Lesser Demons.

Transformation can also corrupt the character's existing personality and beliefs. Saints may lose their holy status, Chaste characters may become Lustful, and immortal mortals who enter the demonic path are converted into the mod's own progression system.

 

Lesser Succubus Progression

Lesser Succubi use four separate progression tracks:

• Power
• Daring
• Corruption
• Loyalty

Sexual encounters can increase several of these tracks.

Long-term relationships also contribute to progression. Lovers can increase Corruption, while Soulmates can increase Loyalty.

Prostitution, demonic interactions, Absorption, and other systems provide additional ways to develop the character.

Sexual encounters may also leave temporary Face Cum, Body Cum, Ass Cum, or Pussy Cum modifiers. These can later become resources for the Succubus through Absorption.

To ascend into a full Succubus, a Lesser Succubus must reach:

• 100 Corruption
• 100 Loyalty

The old advanced-age and Brothel III requirements are no longer necessary.

Once ascended, the Succubus becomes truly immortal.

 

Lesser Demon Progression

Lesser Demons use one primary progression track representing their growing infernal power.

Their progression can be developed through Absorption, ownership and control of slaves, demonic interactions, and other supernatural systems.

To ascend into a full Demon, a Lesser Demon must:

• Complete the progression track
• Reach an advanced age

Alchemy III is no longer a mandatory ascension requirement.

A completed Demon becomes truly immortal.

 

Absorption

Absorption is one of the central progression mechanics.

Lesser Succubi can absorb supernatural residue left on other characters after sexual encounters. Different modifiers can feed different progression tracks.

Lesser Demons use a more direct form of Absorption and can drain or manipulate other characters to develop their own corruption.

Absorption may also involve additional demands such as gold, hooks, conversion, or political concessions.

The system is designed to make character interaction itself part of demonic progression rather than relying only on passive experience gain.

 

Demonic Magic

The mod now includes a broader magic system available to:

• True Demons
• Succubi
• Demons
• Lesser demonic forms with enough progression
• Witches with the required magical resources

Magic is divided into different levels of power.

More powerful workings require stronger infrastructure, more advanced reagents, or greater personal demonic power.

True Demons can bypass most normal infrastructure requirements.

Full Succubi and Demons do not normally consume their progression when casting magic, while Lesser forms may have to spend progression if they cannot provide suitable reagents.

 

Magical Reagents

Three special reagent artifacts support the magic system.

Herbal Vessel

Stores medicinal and occult ingredients gathered from the natural world.

It primarily supports lower-tier magical workings.

Essence Vessel

Stores supernatural vitality collected through intimate encounters.

During a Private Orgy, eligible Witches and Demons can harvest Essence from partners. A temporary seal prevents repeatedly harvesting the same character immediately.

Essence can support stronger magical effects than ordinary herbs.

Ritual Skull

A prepared human skull used for the most powerful rituals.

A magic user can restore its power through ritual sacrifice of a prisoner or owned slave.

Ritual Skulls are required for the strongest tier of magical workings.

Reagent quantity is represented through artifact durability. These artifacts do not naturally decay and cannot simply be repaired with gold; they must be refilled through the appropriate gameplay system.

 

Devil's Gift and Devil's Curse

Devil's Gift and Devil's Curse are now full schemes rather than instant interactions.

Devil's Gift primarily uses Learning, while Devil's Curse primarily uses Intrigue.

Rituals can be prepared at three difficulty levels:

• Simple Ritual
• Advanced Ritual
• Difficult Ritual

More difficult rituals require more preparation and stronger magical resources.

Devil's Gift can provide supernatural benefits, remove limitations, improve characters, alter education or abilities, and grant powerful modifiers.

Devil's Curse can inflict harmful character modifiers, damage counties, spread corruption, create negative province effects, or even unleash epidemic diseases.

Successful curses also interact with the new Puppet system.

 

Puppets and Soul Grip

Demonic magic can bind another character as a Puppet.

The strength of that domination is represented by the Puppet's Soul Grip progression track.

As Soul Grip becomes stronger, increasingly powerful commands become available.

A master can spend Soul Grip to:

• Create or remove personal relationships
• Force friendships or rivalries
• Create Lovers or Soulmates
• Command intimacy
• Rewrite personality traits
• Force religious conversion
• Create political alliances
• Order a Puppet into war
• Compel marriage arrangements

Stronger commands require higher Soul Grip and consume more of it.

Soul Grip is therefore both a measure of control and a resource.

If it is completely exhausted, the supernatural binding breaks and the Puppet is freed.

 

Private Orgy Activity

Eligible adult rulers can now organize a full Private Orgy activity.

The activity supports three sizes:

• Small: up to 20 guests and 3 encounters
• Medium: up to 30 guests and 5 encounters
• Large: up to 40 guests and 7 encounters

The host can also choose between indoor and outdoor venues.

Landless rulers can participate through outdoor gatherings.

The activity contains many different encounter types involving personal relationships, lovers, couples, rulers, lieges, vassals, prostitutes, slaves, competitions, multiple partners, and unexpected social situations.

Possible results include:

• Stress reduction
• New Lovers
• Improved or damaged relationships
• Pregnancy
• Gold
• Prestige
• Character modifiers
• New secrets or social consequences

For magic users, the activity also provides an important source of Essence for occult rituals.

 

Herbal Expedition

Witches and demonic characters can organize a Herbal Expedition to search the surrounding countryside for uncommon magical ingredients.

The expedition lasts three weeks and presents exactly three different discoveries selected from five possible events.

Possible discoveries include:

• A dangerous thorn hedge that may cause wounds
• A Rat King that may trigger a local epidemic
• A young woman suffering menstrual pain who may provide a rare ingredient after successful treatment and diplomacy
• An unknown bitter plant that may be medicinal or poisonous
• A mysterious three-eyed crow

Players can usually ignore a dangerous discovery rather than take the risk.

A Safer Path travel option provides additional Travel Safety.

Successful discoveries refill the Herbal Vessel and provide resources for future magical workings.

 

Saints and Blessings

Holy characters now provide a stronger counterweight to demonic power.

Characters with the Saint trait belonging to Christianity, Islam, or Judaism can bless other characters, while ordinary believers can ask a Saint for a blessing.

The strength of the blessing depends on the Saint's Piety.

Possible blessings include:

• Removing harmful habits
• Replacing sinful personality traits
• Healing injuries
• Healing physical conditions
• Removing negative reputation traits
• Granting positive modifiers
• Cleansing epidemic diseases

Extremely powerful Saints may perform miracles affecting much larger parts of their realm.

Holy characters also play an important role in sealing demons and ultimately closing the Gates of Hell.

Defeating a True Demon is now a major holy achievement.

 

Brothels and Alchemy

The mod contains two important demonic building chains:

• Brothels
• Alchemy facilities

Brothels support Succubus-oriented gameplay and sexual systems.

Alchemy facilities support magic, Devil's Gifts, Devil's Curses, advanced supernatural effects, and demonic military units.

Higher building tiers unlock stronger effects.

The new reagent system also provides an alternative to physical infrastructure, allowing a character with the correct resources to perform magic that would otherwise require access to an appropriate Alchemy building.

True Demons naturally bypass many of these restrictions.

 

Demonic Armies

Demons can recruit unique supernatural Men-at-Arms.

Access is now tied more closely to demonic status and Alchemy progression.

Different Alchemy tiers unlock progressively stronger forces, including:

• Dark demonic armies
• Death Korps
• Zombies
• Skeletons

This makes military progression part of the same infrastructure system used by demonic magic.

 

Devil Deals

Characters suffering from injuries, diseases, stress, physical problems, negative traits, curses, or other serious disadvantages may attempt to Deal with the Devil.

A demonic character or sufficiently prepared Witch may offer supernatural assistance.

Deals can remove or alter a wide variety of conditions, including:

• Diseases
• Injuries
• Genetic disadvantages
• Mental conditions
• Negative modifiers
• Stress
• Body weight problems
• Demonic curses

The price can include gold, favors, hooks, conversion, or other concessions.

More serious problems require stronger magical resources.

 

Slavery and Slave Market

The mod includes an expanded slavery system built around ownership, transactions, training, prostitution, and character control.

A new Buy from Slave Market decision can generate several different market encounters.

Possible offerings include:

• Young male or female slaves
• Children or older captives
• Fallen nobles
• Foreign travelers
• Pairs of slaves
• Families
• Lovers sold together
• Rare high-quality characters

Prices and AI decisions vary depending on the situation.

Slave transactions also include protections against the same character being sold through multiple simultaneous transactions.

Slave Training has been expanded with additional control options involving imprisonment, conversion, punishment, personal service, and other forms of ownership.

 

Prostitution

Prostitution remains integrated with the character and progression systems.

Characters can work as prostitutes, be offered to other characters, or be forced into or out of prostitution under appropriate circumstances.

Sexual encounters use the mod's pregnancy handling and can trigger progression, temporary sexual modifiers, character memories, stress changes, and other effects.

AI evaluation has also been adjusted to better account for personality, sexual behavior, age, immortality, faith, and character circumstances.

 

Makeup and Demonic Appearance

Demonic characters have access to the Makeup interaction for supernatural appearance customization.

Options include demonic horns, unusual eyes, hair changes, nudity, body traits, physique, beauty, and other physical alterations.

The interaction uses the new magic-cost system, meaning weaker demons may need progression or reagents while more powerful demons can use these abilities much more freely.

 

Additional Features

Succubus System also includes:

• Demonic religions and faiths
• Infernal rulers and religious heads
• Character secrets
• Deviant and prostitution mechanics
• Custom demonic modifiers
• Unique interactions
• Special scripted characters
• Religious and demonic conflict
• Sealing the Gates of Hell
• Custom portraits and demonic visual effects
• Relationship manipulation
• Lifestyle and personality interaction
• AI support for many of the mod's systems
• Custom activity and interaction artwork
• Expanded localization support

Succubus System is intended to provide a long-term supernatural campaign in which political power, relationships, sexuality, religion, magic, and character progression all interact with one another rather than existing as isolated mechanics.
