Direct answer: Prepare food, inventory space, and the next tool tier, then advance in milestone-sized pushes. Major seal progression occurs at deep floor intervals; the current release adds dungeon quests and rewards beyond the Early Access picture.
Requirements
- Mines access
- A usable pickaxe and weapon
- Food or recovery options
- Open inventory slots
- Relevant story quests kept current
Step-by-step
- Choose a milestone rather than an endless run
- Carry food and leave low-value items behind
- Break only rocks that serve ore, ladders, or a clear path
- Use checkpoint progress instead of overextending
- Complete seal and dungeon quests as they appear
- Upgrade tools and skills before the next biome
Common reasons it does not work
- Check: Entering with a full backpack
- Check: Spending all stamina before a checkpoint
- Check: Ignoring a seal quest
- Check: Using older floor guidance for new dungeon content

Current-update notes
Known story milestones include the 20/40/60/80/100-floor arc; the page avoids revealing the late-story outcome outside the spoiler box.
FAQ
When should I return to the surface?
Leave enough time to exit safely unless you deliberately accept the fainting penalty. Bank rare artifacts, perfect ore, quest items, and food before pushing a new seal.
What belongs in a mine loadout?
Bring the pickaxe, weapon, at least one strong stamina or health food, and enough empty inventory slots for ore, artifacts, monster drops, fish, and forage from the current biome.
Why is a seal not opening?
Read the active tablet or quest objective and complete every listed offering or dungeon task. Reaching the floor does not automatically satisfy the seal’s story requirement.
Mine biomes and preparation
The mine changes at major floor bands. Treat each biome as a new expedition with different enemies, resources, fish, artifacts, and environmental risks.
| Floors | Biome | Preparation focus |
|---|---|---|
| Upper floors | Upper Mines | Basic weapon, copper, food, inventory space |
| Tide band | Tide Caverns | Iron-tier preparation and water-biome collection |
| Deep band | Deep Earth | Stronger gear, healing, artifact and fish targets |
| Lava band | Lava Caves | Heat-biome enemies, gold resources, safer food stack |
| Final band | Ancient Ruins | Best available gear and late-progression quest checks |
Elevator strategy
Push in milestone-sized runs. Reaching a new elevator stop is more valuable than clearing every rock on a floor that will reset. On collection days, revisit a known band and target its fish, artifacts, monsters, or ore instead of mixing that goal with deep progression.
Loadout
Carry the pickaxe, weapon, one compact food stack, and only the tools required by the run. Empty most of the inventory before entering. Upgrade the weapon and pickaxe when enemies or rock durability begin consuming the entire day.
Major spoiler warning: open seal and late-mine progression
The mine story uses major seal milestones through the deeper floor bands and continues into the Ancient Ruins. The current release completes the mine storyline and adds later dungeon quests and rewards. If the next quest does not appear, clear the current seal event, return to town, read new mail, and allow a normal day for follow-up scenes.
Use tool upgrades, best skills, artifacts, and the complete quest guide to prepare a targeted run.
