FAQ
Answers to common questions about Nightreign Seed Finder.
Does the Seed Finder work in Deep of Night?
Yes, and it is where the tool is worth the most. From depth 3 onward a run has a chance of hiding one thing: either the Nightlord or the points of interest on your map. It is a chance and not a rule, it becomes more frequent the deeper the layer, and it is never both in the same run. With the Nightlord hidden, you mark the map as usual and the result names it. With the points of interest hidden, the terrain, the Nightlord and your own position are all still on screen, so the Nightlord alone takes a Normal map from 240 candidates to 25, marking where you landed usually takes that to about three, and a building or two found on foot finishes it. The guide on identifying a seed in Deep of Night covers both.
Can the app tell if the Nightlord will be the Everdark version during Deep of Night?
No. This information does not affect the map pattern, and the game only reveals this at the very end.
Can the app predict the Mid-Day Circle position or where certain events will spawn?
No. These elements are completely random and there is no reliable way to predict them.
Can you track where Cataclysms will happen?
No, and not because it has not been built yet. Cataclysms are decided while the run is happening, not by the seed, so the same seed produces them in different places on different runs. There is nothing in the record to read. This is the one request that comes up often and cannot be answered, and it is worth being straight about, because killing invaders at a Cataclysm is the strongest strategy in the game right now. The tool covers what the seed fixes. That is not part of it.
Can I increase my chance of getting a specific special event?
You cannot change the odds, but you can choose where to look. The Special Event Hunting page shows which Nightlord and Shifting Earth pairings hold the largest share of records for each event, with the base pool (seeds 000-319, the eight base Nightlords) and the DLC pool (seeds 1000-1199, the Balancers and Greg) counted apart. Limveld records are counted nowhere on it. What you get from it is a share of records in the dataset, not the odds the game rolls.
Does this website use cheating methods or extract information illegitimately from the game?
No, and the reason is worth stating plainly. The site never touches the game. It runs in your browser, it does not read or modify the game process, its memory, or its files on your device, and it does not automate any part of a run. What it gives you is information: records compiled for this site from analysis of structured game data and from observations that can be checked in normal play. Knowing a layout before you land is the same category of knowledge as a wiki page, a boss guide, or a friend telling you what is behind a door. The line that matters is between knowing something about the game and interfering with the game, and everything here sits on the knowing side of it. The Methodology page covers where the records came from, and the Legal page states the position in full.
Is it unfair to my teammates or to other players?
An advantage that comes from information the community already shared is not taken from anyone. Nobody has less because you read a map layout first, the same way nobody loses when you look up a boss before fighting it. The question worth asking your squad is about spoilers rather than fairness. If you call out a night boss or a chest location, you have decided for everyone else that they wanted to know it. Some players want exactly that. Others would rather find it themselves, so ask first, or keep the result page to yourself and just suggest the route.
Where does the seed data come from?
The 520 records covering map type, Nightlord, special event and where each location sits were compiled and verified by Artimuz for this site, along with the marker files and the boss data. The building icons are composites of symbols the game already uses: 33 of the 53 merge a structure with the affinity or status effect it carries, because the game keeps the two apart and a player sees them together. The artwork belongs to FromSoftware; what Artimuz did was choose the pairs and composite them. Two data miners informed the project when it started in 2025: thefifthmatt, whose published catalogue was the reference at the time, and kevins78, for the Great Hollow and DLC-era material. The Methodology page carries the full provenance.
Is the DLC covered, and how much of it?
All of it, as far as the dataset goes. The base game has 320 seeds, ids 000 to 319, across Normal, Crater, Mountaintop, Rotted Woods and Noklateo. The DLC adds 200 more, ids 1000 to 1199, of which 80 are the new Great Hollow map and the other 120 are spread across those same five Limveld maps, for 520 in total. Blacksmith Village and Marsh are DLC structures: they appear in none of the 320 base seeds and in all 120 DLC Limveld seeds, so spotting either one tells you immediately that you are in DLC scope.
Which game version is the data for?
The dataset targets game version 1.03.2, and every result page says so. If a game update changes a layout, use the Bug Report button in the footer and include the seed ID.
If the app shows the wrong map, how can I report it?
In the bottom-right corner of the footer, there is a "Bug Report" button. It opens a short form where you can describe your case.
Can you implement a way to identify a map pattern using only a screenshot?
This is technically possible, but it would significantly increase computational cost, be prone to errors, and overall be less reliable than manually identifying 2 to 5 structures on the map.
Does the site work on a phone?
Yes. Phone support was added after players asked for it in the Steam forums, and it is maintained as a first-class case rather than a fallback. There is a minimalist mode and a sidebar you can hide to give the map more room.
Does the site save my data?
Two separate things happen. Your browser keeps preferences in localStorage: a pre-selected Nightlord, whether the Nightlord status card is pinned, marker toggles and colours, minimalist mode, whether the sidebar is hidden, the last path you marked (so it can be attached to a bug report if you send one), and your viewport size. On the server, when a seed is identified, one row is written to a logs table containing the seed id found, the marks that led there, the Nightlord, how many searches the browser has made, a random per-browser identifier, timezone, platform, viewport size, and which markers were enabled. That row does not carry an IP address. There is no account system and no login, and nothing in that row asks for a name or an email. The bug report form is the exception on both counts. You fill it in yourself, it asks for a name and an email, and it does record the IP it arrived from, which is there to catch abuse of an open form. It also carries the same random browser identifier the seed log uses, so sending a report attaches the name and email you typed to the searches logged from that browser. Email us instead of using the form if you would rather not make that connection. For what advertising partners collect, see the Privacy Policy.
