Each underworld is a distinct mythic scenario with its own threats, palette, and story paths. Runs are designed to be replayed with different helpers and choices, take about an hour, save automatically, and provide a synopsis so a session can be resumed without replaying the entire descent.
This guide separates confirmed systems from launch-day discoveries. It does not turn an unverified demo observation into a permanent ranking, exact location, boss weakness, ending route, or drop rate.
Confirmed Mechanics
| Evidence | What is confirmed |
|---|---|
| 1 | Examples include an Orpheus-like rescue and saving the Eternal City from an insect plague. |
| 2 | Eight writers contributed to the anthology and hundreds of hand-painted illustrations support it. |
| 3 | A mission uses a party of four heroes. |
| 4 | Each hero has a profession, skills, traits, and personality. |
Steps
- Start a run only after reading its underworld and contract premise.
- Use the automatic save when a session must end.
- Read the synopsis before resuming so prior injuries and choices are fresh.
- On a replay, deliberately change party coverage or one major risk path.
Requirements
- Use the build identified above; launch balance may differ from the demo.
- Reach or unlock the named system before troubleshooting it.
- Keep the official store page or developer notes available when checking changed controls or requirements.
Common Problems
- Do not expect a fixed encounter order across different generated quests.
- Restarting after every setback works against a design where failure can create new story state.
FAQ
Is this system officially confirmed?
Yes. The system and boundaries on this page come from the official Steam description or developer update linked below. Any unconfirmed detail is stated as such.
Can demo advice be treated as final launch balance?
No. A demo establishes that a mechanic exists, but values, item pools, encounter order, saves, and balance may change. Recheck the launch build before publishing exact statistics.
What should I avoid claiming before release?
Do not publish permanent tier lists, exact boss weaknesses, every item location, endings, drop rates, or save-transfer promises unless the developer or release build verifies them.
