What the Ancient Hot Spring Does

The Ancient Hot Spring is the best relaxation facility in the game, filled with special Paldium-infused water. Base pals soak in it on breaks to restore SAN, and it recovers sanity at 2 per second — double the Japanese-Style Hot Spring and four times the basic Hot Spring. Per its in-game description it also restores Health while pals bathe, and can fully heal injured pals.

How to Use It

  • Unlocked at level 76 in the technology tree for 5 technology points.
  • It needs no assigned pal and no power — pals use it on their own when their SAN runs low. It must be built within your base's radius.
  • It occupies the same footprint as a standard hot spring, so it's a drop-in replacement in existing layouts.

How It Compares

Faster recovery means shorter breaks: pals top up their SAN and get back to work in half the time they'd spend at a Japanese-Style Hot Spring. Combined with the Ancient Pal Bed for overnight recovery and the Ancient Clinic to slow the drain, it forms the welfare backbone of a hard-working endgame base.
