Corruption

Introduction
Corruption is a stat for each of the Princesses, that starts at 0 and can go up to 10. It represents the princess' surrender to wanton pleasure, which breaks her mind at high levels.

Corruption can be tracked via the diary for each princess.

Battle Fucking
The main way of increasing corruption is through Battle Fucking. To enter a battle fuck, these conditions must be true:


 * Battle Fucking is enabled in the game's settings.
 * The princess must have a Lust stat greater than 0.
 * The princess is the active party member and must be hit by an enemy (not a miss or dodge).

If the above conditions are satisfied, they have a chance (scales with Lust?) to enter a sex scene with the enemy that they are currently fighting. The mechanics are as follows:


 * On every thrust, the princess loses HP. The more Lust she has, the more HP she loses per thrust.
 * Once the princess' HP is depleted, the enemy ejaculates. You return to the main battle with the following consequences:
 * The princess preserves 1 HP, and cannot participate in further battles until you heal her. You are automatically switched out to the next available party member.
 * The princess' Corruption has a chance to increase by 1.
 * The princess may become impregnated.
 * You collect 1-3 sperm of the enemy's type.
 * The princess can escape the sex if you repeatedly mash the left and right arrow keys alternatingly.

Aphrodisiac Consumables
Testos-X is an item which can be bought from Trevor for 500 Swirlies each, and can be used on a princess at a campsite. This will enable the Knight to have sex with them even if they normally would not be interested, but using Testos-X will also increase that princess' Corruption by 1. Only 1 Testos-X can be used per campsite.

Moth Dust is a re-usable version of Testos-X, obtained as a dowry from Moth Princess. Using Moth Dust counts as a Testos-X use, and you will not be able to use more Testos-X in the same campsite.

Equipped Items
The Nya Nya Doll may raise Corruption while equipped on a princess.

Preventing Corruption
One can avoid Corruption entirely by simply avoiding battle fucking:


 * Turning the Battle Fuck option off will prevent princesses from having sex during battle.
 * Keeping a princess' Lust stat at 0 will prevent them from having sex during battle.


 * Equipping a princess with a Chastity Belt will drop their Lust to 0, having the same effect.
 * One can be found in a box in the Chapel.
 * Amelie, when recruited, comes equipped with one.
 * More can be bought from a nun at the Monastery for 500 Swirlies each.


 * If a princess is never involved in combat (or if they at least never take damage), they will never engage in Battle Fuck and their Corruption will not increase.

Naturally, one should also avoid using any items that raise Corruption.

Removing Corruption
If a princess is still below max Corruption, you can visit the nun in the Chapel or to one of the nuns in the Monastery in order to reset their Corruption to 0, costing 500 Swirlies per point of Corruption. At max Corruption, the nun will say there is nothing she can do now.

You can also use a Prayer: Purify item to reset the Corruption to 0.

Succubization
As of v0.17.5, upon reaching max corruption, there is a chance that the princess will transform into a succubus version of herself at the end the next camp that she attends. Her Corruption is reset back to 0, and she experiences the following indefinite changes:


 * The appearance of the princess and (?) any further progeny changes. (Does not affect any progeny she's pregnant with before succubization.)
 * The princess can now equip whips and swords regardless of their race.
 * Equipping and hitting enemies with the Love Whip enters offensive battle fucking, which is the same as normal battle fucking, except that the enemy takes damage during sex instead of the princess, and the enemy ejaculates when their health (and not the princess') depletes.
 * The animation exits on its own after a while, so you do not stunlock an enemy to death.
 * Boss-type enemies also won't be entranced by the Love Whip.
 * Battle fucking (both normal and offensive) has a significantly reduced chance of increasing Corruption.
 * The levels of the normal and succubus forms are separate, (?) but the princess preserves her existing stats. This lets the princess to gain high stats by leveling up in both normal and succubus forms.
 * The princess now feeds on sex.
 * At night, the princess can fly.
 * Talking to the princess in camp forces The Knight to spend the night with her. Attempts to leave will be stopped by the princess, and you'll be forced to go another round. If you do not have enough Endurance to survive the night, it's game over.
 * The Knight may spend up to 6 Endurance. Have a few Princess’ Spring Water on hand, or equip the Knight with a Clockwork Key, to survive the night.
 * Spending the night with your other party members, or going to sleep by yourself uneventfully, are unaffected.
 * Along with the usual animations in battle-fucking or camping, unique succubus animations (if the princess has them) are available as well.

Letting a succubized princess reach max corruption again causes them to enter a "broken" state, where they will (?) no longer accept any sex in camp or initiate/progress any quests or character development. On the next camp (?), they will return to Faun's Tavern and will not rejoin the party or do anything else, thus becoming unplayable.


 * Showing a succubized princess to the nun at the Chapel makes her kick the party out of the Chapel in horror. (You can re-enter with no problems.) You thus cannot remove Corruption through this method.
 * (?) Human Princess will still be regarded by the nun as a normal princess with Corruption (and using the nun reverts HumanP back to her normal form), and will not retire herself to the Tavern when at max Corruption. (The nun will regard her as a normal princess at max Corruption.) However, if intentionally returned to the Tavern, she will act like any other "broken" princess.
 * Returning to human form prompts a line of dialogue from HumanP suggesting that she was unaware of what happened while she was a succubus.
 * Using Prayer: Purify resets both the Corruption level and the succubization. This is the only way to rescue a "broken" princess.

Before v0.17.5, only the Human Princess will be succubized, while the other princesses (lacking a succubus form) will enter the "broken" state directly.

Trivia

 * There is a cheat that immediately succubizes all princesses, including ones currently on the throne.
 * Using this cheat to succubize princesses does not reset their Corruption to 0 - they will keep their current Corruption level.
 * Visiting a succubized princess still on the throne while she is sleeping gives you access to her succubus animations, but all other interactions are normal, e.g. she will not force you to have sex the whole night / until you die.
