The route is a defeat condition, not a floor-reached condition.
01
Start from B110F
Use the nearest confirmed Quarry minecart/checkpoint and plan the final descent.
02
Defeat the boss
Reach B120F and defeat the deepest-floor Quarry boss. Do not stop at simply reaching the floor.
03
Return the next day
After the defeat, the Hot Spring becomes available in the mountain area northwest of the village.
For every floor, ore table, Pickaxe tier and checkpoint detail, use the Mining guide. This page owns only the Hot Spring unlock and use loop.
Boss strategy
Rush, keep moving, punish the eye
The public guide uses the stable encounter pattern without inventing an official English name or unsupported combat numbers.
- Move as soon as the charge or falling-rock warning appears.
- Stay clear of the attack line instead of trying to trade hits.
- Wait for the boss to stop and expose its eye.
- Attack the eye opening, then resume moving when the next telegraph begins.
What this guide does not promise
No exact HP, damage value, phase count, required weapon, mandatory story prerequisite or clock-pause exploit is part of the canonical Hot Spring data.

A bath costs 60 game minutes. A fee, daily use limit and exact latest-entry rule are not asserted in the current canonical data.
Compare systems
Hot Spring vs Fox Shrine
Both mention stamina, but they do different jobs.
The Hot Spring restores current stamina after the Quarry unlock. Fox Shrine offerings reward Fox Fried Tofu, which increases maximum stamina. Do not use the Hot Spring as evidence of a permanent stat increase.

Hot Spring questions
How do I unlock the Hot Spring?
Use the Quarry checkpoint at B110F, descend to B120F, defeat the boss there, and return the next day. The spring becomes available after that unlock.
Do I only need to reach B120F?
No. Reaching B120F is not enough; the unlock condition is defeating the deepest-floor Quarry boss.
Is there a direct B120F warp?
This guide does not claim one. Use the confirmed B110F checkpoint and continue downward.
What is the Quarry boss's official English name?
No canonical English name is established here. Use “Quarry B120F boss” or “deepest-floor Quarry boss.”
How should I approach the boss?
Keep moving through the charge and falling-rock telegraphs. When the boss stops and exposes its eye, attack that opening, then repeat the evade-and-punish rhythm.
When can I use the spring?
The current unlock chain treats it as available the next day after the B120F boss defeat.
Where is the Hot Spring?
It is in the mountain area northwest of the village. This page intentionally avoids an unverified coordinate.
What does the Hot Spring restore?
It restores your current stamina to its maximum.
Does it restore HP?
No. The Hot Spring restores stamina, not HP.
Does it increase maximum stamina?
No. Fox Shrine offerings and Fox Fried Tofu are the separate maximum-stamina progression; the Hot Spring is a refill.
How much time does bathing cost?
One in-game hour, or 60 game minutes if expressed in minutes.
What is Liquid Assets?
Liquid Assets / 致富 is the achievement tied to discovering and striking the Hot Spring in the Quarry.
