Direct answer
Investigating a Mystery in Welcome to Elderfield triggers a dice roll influenced by Luck. Outcomes can provide rewards or cause curses, damage, and combat. Bathing can reset Mysteries for another investigation opportunity, but that does not prove every unique first-time reward can be collected repeatedly.
Official updates were checked on September 29, 2026. The latest documented full-game announcement is v1.0.2a, dated September 23; the separate Demo has a v1.0.0 changelog dated September 8. Older Demo and alpha research below retains its original evidence boundaries. These announcement versions do not guarantee which build is installed on your device. Full-game, Demo, and Patreon changes are kept separate throughout the guide.
What the research confirms
The Mall ATM is a verified investigation event that can grant a blessing and money. Separate footage shows outcomes of thirty-five and fifty gold, which are different rolls rather than a fixed reward conflict. Demo v0.11.17 includes a Fast die-roll-speed option, but that setting changes presentation speed and is not evidence of better odds.
Confirmed here means either an official source states the point directly or two independent sources agree on the same observable behavior. It does not mean every related number, location, or unlock condition is known. Exact values stay out of the confirmed section unless the collected material supports them at the same version level.
How to use this information
Raise Luck only when the current equipment or interface supports it, then treat each investigation as a risk-reward choice. Restore and save before testing an object that may inflict a persistent penalty or start combat. Use bathing to refresh the system only after confirming what else the action changes in your current build.
Use the confirmed sequence first and check the in-game wording before committing rare materials or long sessions. Interface labels and broad mechanics are more stable than balance values, rewards, and exact routes during development. A step marked Pending verification (待确认) is a research lead, not a guaranteed instruction for the current build.
Demo, Alpha, and launch boundaries
A versionless table claims hidden outcomes outside the normal range and gives exact rewards for a Parks and Recreation altar, a Mall tree, a smoothie-shop mass, and an Old Woods well. Those rows lack current independent support. They remain Pending verification (待确认), especially where an area may belong to Patreon content.
Welcome to Elderfield launched on Steam on September 10, 2026. Its public Demo and older itch or Patreon builds remain separate evidence. A detail can be authentic and still be obsolete or unavailable in another channel. Historical footage is not automatically proof of the released game's balance or unlock requirements.
Pending verification (待确认)
The full Mystery location table, exact roll probabilities, one-time reward flags, and every hidden outcome are unknown. Fish Door, Four Sacred Numbers, telephone, laundry-machine, and Old Woods riddle solutions were not verified by the general Mystery research. Incomplete table cells are not answers and must not be filled by pattern guessing.
Pending verification (待确认) means the collected sources did not reach the required confidence threshold. It may be supported by one guide, one developer comment, or footage whose build cannot be identified, but it lacks a matching current source. These points are retained because players search for them, while their uncertainty remains visible.
