Honesty pass
Where this data came from, and what's missing
Every zone's level number and monster names come from the official wiki's per-zone infobox (soulsremnant.wiki.gg), cross-checked against fan-wiki leveling guides where they overlap. The three playstyle presets' level-gap windows (Safer, At-level, Overleveled) are arithmetic on top of that real data.
Drop rates (561 exact percentages across 57 monsters), monster levels and stats, every skill's real Power / scaling / MP / SP / cooldown numbers (what the planner's DPS engine runs on), and the full 477-item equipment database with stat ranges and echo slot counts all come from the official wiki's internal data modules, the same structured data its own pages render from. The Echoes page's translations are the game's own localization strings for all 17 languages, from the client files.
Per-zone terrain (holes, cliffs, platform layout) isn't in the datamined client files - the actual tile geometry is sent by the server at runtime, not shipped locally, so no amount of further file-digging recovers it. It's also almost entirely undocumented on every public wiki checked. Only two zones have any confirmed terrain text at all (flagged in the ladder). Treat the checklist above as the real substitute.
The exact aggro-dropout level threshold has no published number anywhere. A couple of "Map Level 0" entries in the raw wiki data are almost certainly unfilled stub fields, not real level-0 zones - excluded from this ladder where the surrounding chain made that obvious.
The Echoes page's two linked reference spreadsheets are hand-compiled by named community members, not wiki staff - credit to Flim for "Equipment Echoes w/ Calamity Gem" and Rajah for "Echo Line Probs Percent." Both are linked directly from that page and from here. The same page's pink-line rerolling guide is written by community member Desolo, adapted from their Discord post with permission - full guide and a link to the original post are on the Echoes page.
Primary source: soulsremnant.wiki.gg (official wiki) - Maps index, Grinding page, and ~80 individual zone pages. Cross-checked against fan wikis (soul-remnant.wiki, soulsremnant.org, soulsremnant.wiki) and Steam Community discussions for the game (app 3451980) where noted inline above.
Echo data on the Echoes page: game's own client files (item/modifier scripts) for the full modifier list, official wiki's Echo and Equipment pages for slot/pool structure, and two community Google Sheets for the deeper reference data - Equipment Echoes w/ Calamity Gem by Flim, and Echo Line Probs Percent by Rajah.
Drop rates, monster stats, skill numbers, and the gear database: the official wiki's internal data modules (its Monsters, Skills, and Equipment databases), fetched directly rather than scraped off rendered pages. The planner's damage formulas come from the game's own client code (its damage and build-simulator scripts plus formula constants). Modifier-line translations: the game's shipped localization files.
The Mystery Tickets page's 60-item reward list: official wiki's Mystery Tickets page - not recovered from this project's own datamined client files. Redemption odds aren't published there or anywhere else, and that page says so plainly rather than guessing.
