Hemogen

For stored hemogen, see hemogen pack.

A reserve of biological strength which can be gained and spent in a variety of ways. Hemogen can be increased by bloodfeeding from a human or consuming hemogen packs. You can obtain hemogen packs using the 'extract hemogen pack' medical operation on a non-hemogenic human. If hemogen reaches zero, [they] will become very unhappy.

— Hemogen description

Hemogen is a measure of the need and reserves of hemogenic pawns to fuel their bodies and abilities.

Hemogen total

Hemogen gizmo showing a hemogen value of 88, maximum of 100, a target hemogen of 90, and hemogen pack consumption allowed

A pawn's current hemogen total and their maximum hemogen is displayed in a gizmo to the right of their info pane when the pawn is selected. The current hemogen total can be increased by consuming hemogen as detailed below, and is reduced through daily decay and use of abilities. The maximum hemogen is the cap on how much hemogen a pawn can hold. Any hemogen consumed that would put the total over this value is wasted. By default the maximum is 100 but pawns that can deathrest can increase it through the use hemopumps at at a rate of +25 per pump.

The gizmo also allows the selection of target value by left clicking on the bar, displayed as a white line over the bar ^{[Change with max change?]}- the pawn will then atuomatically attempt to consume hemogen packs or bloodfeed from prisoners designated for bloodfeeding to reach that value ^{[Reach or exceed?][Frequency?][Priorities?]}

Decay

Pawns with the hemogenic gene decay at -2 per day.

Pawns with the hemogen drain gene decay at an addition -8 per day, for a total of -10 per day.

While the rates are known, it is currently unknown when or in what quantity this decrement occurs.^[Detail]

Abilities

Ability		Hemogen
	Bloodfeed	+20
	Coagulate	−20
	Longjump	−5
	Piercing spine	−20

Hemogen craving

Due to a lack of hemogen, this person's body is breaking down hemogen reserves in their bone marrow. This causes disorientation and a painful craving for human blood.

— Description

When a hemogenic pawns hemogen reserves hit 0, they begin having a craving for hemogen. This craving inflicts increasingly severe mood, pain, and consciousness penalties. Once hemogen is over 0, the severity of the craving gradually decays until it disappears.

While a pawn hemogen value is 0, their hemogen craving severity at a rate of +5% per hour. While the rate is known, it is currently unknown when or in what increment this severity increase occurs.^[Detail]

So long as hemogen is above 0, hemogen craving severity reduces at a rate of −10% per hour. Hemogen craving does not accelerate hemogen decay like malnutrition does for saturation.

Label	Severity	Time from 0 Hemogen	Time to 0% Severity (Upper)	Mood	Pain	Consciousness
Minor	>0% and ≤34%	0 ticks (0 in-game hours)	8,750 ticks (3.5 in-game hours)	−10	− 5%	90% Max
Moderate	≥35% and ≤69%	17,500 ticks (7 in-game hours)	17,500 ticks (7 in-game hours)	−15	−10%	80% Max
Major	≥70% and ≤100%	35,000 ticks (14 in-game hours)	50,000 ticks (20 in-game hours)	−20	−15%	50% Max

Note: Mood penalty does not include the penalty from pain.
