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 (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.
