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
- Hot Spring — 0.5 SAN/s
- High Quality Hot Spring — 0.75 SAN/s
- Japanese-Style Hot Spring — 1 SAN/s
- Ancient Hot Spring — 2 SAN/s
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.
