Psychic harmonizer

The Psychic Harmonizer is a special psychic implant that projects the mood of the user to other pawns.

Acquisition

Psychic harmonizers cannot be crafted, and instead must be acquired through trade or as a quest reward.

Summary

Once implanted in a pawn, the harmonizer projects a psychic effect with a radius of 30 tiles that affects nearby pawns with a moodlet whose value is dependent on the current mood of the implanted pawn. It base value scales from -? at 0% Implantee Mood, up to +10 at 100% mood.

This value is then proportionally scaled by Psychic Sensitivity of both the implantee and the subject of the effect. If a 100% happy implantee has 200% sensitivity, they'd give +20 mood buff. If a subject also has 200% psychic sensitivity, they would receive a +40 mood buff.

It only impacts members of the same faction, and pawns without a psychic harmonizer of their own. Mood bonuses from different harmonizers stack on pawns that meet the prior two criteria, however.

Slaves are considered to be part of their owners' faction for the purposes of the psychic harmonizer, not of their original faction.

Installation

Installing the part requires 2,500 ticks (41.67 secs) of work, 2x medicine of herbal quality or better, and a Medical skill of 5.

Removing the part requires 2,500 ticks (41.67 secs) of work, 1x medicine of herbal quality or better, and a Medical skill of 5.

If the operation fails, the part has a chance^{[What Chance?]} to be destroyed.

Analysis

Psychic harmonizers can be an extremely powerful tool to keep your pawns happy, if you install it in a pawn who is easily pleased. But if the pawn gets upset, it can quickly cause a "death spiral" of mood.

Pawn Choice

The following aspects lend well to being a (motile) harmonizer pawn:

Positive mood traits: Sanguine and Optimist have the most straightforward effect on the implantee's mood. Other traits like Body modder, Masochist, and Bloodlust also work well. Note that traits that impact Mental Break Threshold, like Iron-willed and Nervous, have 0 impact on the harmonizer.
High Psychic Sensitivity: The higher the sensitivity, the greater the mood buff. It also means a greater effect from a psychic drone, so be very careful with this. Eltex gear and psychic foil helmets can be used to modify psychic sensitivity as needed.
Pawns that will naturally be near other pawns. For example, a psycaster can meditate all day (which also counts as Recreation) in 1 place. A passionate crafter can sit in a chair all day, gaining mood from the passion and the comfort of their chair.
"Disposable" pawns. Drugs and joywires may slow the work of a hauler, but do you really need that extra workspeed?

Comatose pawns

A pawn's mood does not change when unconscious. If you can stack mood to 100%, then make a pawn comatose, you'll end up with a permanent +10 moodlet (so long as the pawn is fed). Because the pawn is unconscious, even a psychic drone won't bother them, meaning you can stack Psychic Sensitivity as much as you want.

The easiest way to do this is with the Biotech DLC. A pawn with the Deathrest gene can willingly enter deathrest, where mood is frozen, and stay in this state indefinitely. A deathrester can be woken on-command, allowing you to replace eltex gear as needed. As a side benefit, pawns don't need food during deathrest.
An alternative method is to use brain damage. You can use an already comatose pawn, but if needed, the fastest way to cause brain damage is to fail to install a brain implant (like a painstopper). If further Consciousness reduction is needed, you can use a joywire (-20%) and circadian half-cycler (-15%). If you need to make the pawn conscious again, then

Regardless of method, your patient should have the highest mood and highest Psychic Sensitivity as possible. Using some combination of yayo, flake, psychite tea, beer, lavish meals, and fine meals should get all but the most ruined pawns to 100% mood.
