What Insomnia Does

Insomnia makes the Pal nocturnal: it doesn't sleep and keeps working straight through the night. On a base worker that's up to a third more output from the same Pal — the whole night shift, free.

The catch is sanity: sleep is how Pals recover SAN, so an Insomnia worker burns it around the clock. Pair it with Positive Thinker or Workaholic , keep a hot spring nearby, and serve decent food, or the extra hours disappear into breakdowns. Avoid stacking it with SAN-hungry passives like Demon’s Hand unless your base's recovery is excellent.

Related passives: Night Owl trades the day shift for the night one instead of adding it, and Vampiric bundles nocturnal activity with life steal for combat Pals.

How to Get It

Insomnia is one of the default options at the Pal Surgery Table — no implant needed, 10,000 gold per surgery. It also rolls on wild Pals like any common passive. See the implants guide for how surgery works.
