About Crimson Moon Grimoire

Crimson Moon Grimoire is an independent, player-run reference for Crimson Moon. Every table on the site is transcribed from a named primary source — the developer-run Crimson Moon Wiki, the ProbablyMonsters support articles, the studio's Steam posts and the public Steam achievement data — and each page names its sources at the bottom.

This site is not affiliated with, endorsed by, or sponsored by ProbablyMonsters. All trademarks belong to their respective owners. Screenshots are the official Steam store screenshots; the trailer is embedded from the studio's own YouTube channel.

Editorial policy

• How we verify: Every table row is copied from a primary source and labelled: weapon, shield, armor, Boon, trinket and Weapon Art text from the developer-run Crimson Moon Wiki, controls and system rules from the ProbablyMonsters support articles, achievement names and unlock rates from the live Steam achievement list for app 4317690.
• Update cadence: Launch-week posts get read the day they ship — the keybinding notice and the Known Issues list both landed on September 1 — and when Hotfix 1.0.1 publishes its notes, every table it touches is re-checked before that page’s date changes.
• What we don't do: No S/A/B tier list: the game publishes no damage numbers, so ranking weapons would be invention. No leaked content, no “free download” links, and where two official sources disagree — who sells rings, which shop stocks trinkets — both versions are shown with their source instead of quietly picking one.

Where a fact is unconfirmed we say so with a date rather than guessing. If you spot an error, please contact us and we will fix it.
