Prison Cell

How to capture a Prisoner
is a Vampire Power that allows you to charm human targets and convert them into loyal Servants or Prisoners.

To successfully charm a target for conversion to a Servant, you must first reduce their health below 30%, activate, and channel the (default key R) to dominate the target. The target may still attack during the channel.

Once a target is dominated / charmed they will enter a neutral, dormant state where their attacks are disabled, but they can still take damage from enemies. They can then be imprisoned.

Perks

 * Has Matching Floor (Prison Flooring): -25% Blood Drain & Essence Extraction health costs.

Usage
Once a victim has been imprisoned, multiple actions may be performed on them: Drain Blood, Extract Blood Essence, Feed Prisoner, Charm & Kill.

Drain Blood
The first, and primary use case for the Prison Cell, is to drain a victim's blood to fill s, creating s the player can drink to maintain a blood type & quality equal to the victim's. This can be repeated indefinitely at the cost of -30% ~ -60% of their health, and a +5% ~ +20% increase to their misery percentage.

If the victim suffers too much damage and runs out of health, they will be permanently killed. It is therefore recommended to always ensure that a prisoner is well-fed before their blood is drained. Additionally, a prisoner's misery also has to be taken into account, as their damage taken will be increased by that percentage.

Assuming a full health prisoner, their blood can be drained safely at any misery level below 66.6%, or 122% with the Prison Flooring bonus active. For comparison, a prisoner at 70% max health, can only be drained safely at any misery level below 16.6%, or 55.5% with the Prison Flooring bonus active. See the formula below:

$$Max\ Drain\ Blood\ Damage\ % = 60 \times (1 + Misery%)\times (1 - Floor\ Bonus%)$$

Extract Blood Essence
The second, less relevant use case for prisoners, is to extract s from them, at a cost of -10% ~ -30% of their health and a +2% ~ +6% increase to their misery percentage.

Feed Prisoner
Feeding prisoners is how their health is restored, as well as how their misery may be reduced. See below.

Charm & Kill
Recharming a prisoner allows them to be moved to a different Prison Cell or put in a. Note that conversion to a Servant is irreversible. Finally, they may also be killed outright. There is no option to set a prisoner free.

Werewolves
An imprisoned human with werewolf capability, will turn back into a werewolf at night. Previously this would cause them to escape their cell, but with the Gloomrot expansion they now remain imprisoned, and retain their blood quality, allowing their creature blood to be drained.
