Chemical (Need)

This article is about the need created by chemical need traits. For the need created by addiction, see Addiction.

Chemical need is the game mechanic that controls the need of Characters with the Chemical interest or Chemical fascination traits to consume social and hard drugs of any kind, distinct from addictions. A character with a higher chemical value has consumed drugs recently, and has fulfilled that need more than another character with a low chemical level. Only pawns with those traits have the need. You can view the chemical need of any affected human by viewing the "Chemical" bar and the corresponding mouseover text in the Needs tab.

Pawns with this need that spend too long without consuming drugs will become increasingly unhappy, while satisfying the need provides a mood bonus.

"Chemical expresses the desire to ingest drugs. When above a certain level it will create good mood, but when below a certain level it will create increasingly bad mood."

Need changes

The chemical need is fulfilled by consuming certain drugs:

• Social drugs satisfy the need by +20%. Social drugs include: Ambrosia, Beer, Psychite tea, Smokeleaf joint.
• Hard drugs satisfy the need by +30%. Hard drugs include: Flake, Go-juice, Wake-up, Yayo.
• Medical drugs have no effect. Medical drugs include: Luciferium, Penoxycyline.

The need satisfaction decreases at a base rate of −7.1% per day, it does not change while the pawn is sleeping, however. The actual rate the need ticks down is dependent on two factors; the trait causing the need, and the current value of the need. The value decreases every 150 ticks (2.5 secs).

The end result is that Chemically Fascinated pawns need

Need thresholds

A character's chemical need level is divided by five thresholds: "Chemical starvation", "Chemical hunger", "Chemical want", "Chemical comfort", and "Chemical satisfaction". These thresholds determine when the mood buffs and penalties are applied. The thresholds are indicated by small notches on the "Chemical" bar in the tab of pawns with this need.

The location of each threshold and the magnitude of the mood effect is dependent on whether the pawn in question has the Chemical Interest or Chemical Fascination trait.

Chemical interest

Chemical interest
Label	Saturation	Mood modifier
Chemical starvation	0% - 1%	−6
Chemical hunger	2% - 15%	−4
Chemical want	16% - 30%	−2
N/A	30% - 60%	0
Chemical comfort	60% - 75%	+1
Chemical satisfaction	75% - 100%	+3

Taking one social drug every 2.8 days or one hard drug every 3.5 days should be more than enough to keep a pawn with chemical interest above the chemical satisfaction threshold.

Chemical fascination

Chemical fascination
Label	Saturation	Mood modifier
Chemical starvation	0% - 10%	−12
Chemical hunger	11% - 25%	−8
Chemical want	26% - 40%	−4
N/A	41% - 70%	0
Chemical comfort	71% - 85%	+3
Chemical satisfaction	85% - 100%	+6

Taking one social or hard drug every 2.1 days should be more than enough to keep a pawn with chemical fascination above the chemical satisfaction threshold.
