The Circadian Assistant decreases the amount of sleep required by a pawn.

Acquisition

Circadian assistants can be crafted at a Fabrication bench once the Circadian influence research project has been completed. The required techprint can be obtained either by trade or completing quests for the Empire. They require Plasteel 15 Plasteel, Advanced component 4 Advanced components, 26,000 ticks (7.22 mins) of work, and a Crafting skill of 8.

Pawns from ancient shrines may have this implant installed.

Summary

An installed circadian assistant decreases Rest Fall Rate by −20%. This increases "Time Awake per Time Rest" by +25%.

This does not equal 20% or 25% less sleep. See Sleep Saved for the exact details.

When a pawn with this implant is shocked with EMP, they will receive brain shock, knocking them unconscious temporarily.

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

Sleep saved

In essence, the circadian assistant only has an effect while the pawn is awake. Therefore, actual sleep saving will always be lower than expected values.

For example, let's assume that a pawn spends 7.56 hours sleeping, and X hours awake. This is enough sleep to get a baseline pawn, in a normal bed, from "Drowsy" to full Rest. The circadian assistant increases X to (X/0.8), without impacting sleep time. Therefore:

  • A baseline pawn would spend (7.56 hr asleep) + (18.19 hr awake) = 25.75 hr in a "true" sleep cycle.
    • (18.19 hr awake) / (25.75 hr total) = 70.6% day awake - or 16.95 hr per 24 hour cycle.
  • The same pawn with a circadian assistant would spend (7.56 hr asleep) + ([18.19 / 0.8] = 22.74 hr awake) = 30.3 hr in a "true" sleep cycle.
    • (22.74 hr awake) / (30.30 hr total) = 75.04% day awake - or 18.01 hr per 24 hour cycle.

This means that the circadian assistant actually increases awake time by +4.44%, about 1 hour per day, rather than the expected +20% or +25%. Increasing Rest Effectiveness or Rest Rate Multiplier will actually lower the amount of time savings of the circadian assistant.

Notes

Despite its description, it does nothing to mitigate toxic buildup.
