Spire Codex - Ultimate Companion & Stats Aggregator

Spire Codex brings the power of spire-codex.com directly into Slay the Spire 2. No more alt-tabbing to check stats mid-run.

Whether you're new to the climb or grinding Ascension 10, Spire Codex gives you data-driven insight (Codex Elo + Codex Score) at a glance to help you make winning decisions. When your run ends it's automatically saved to https://spire-codex.com.

- Automatic run tracking: Every run uploads and competes on the leaderboards, and gets its own shareable page on the website.
- In-game community tooltips: Win rates and Codex tiers shown natively on the game's own tooltips for cards, relics, potions, events, and campfire options.
- Stat brackets: Filter the community numbers by bracket (All runs, Ascension 10, or higher win-rate players) so you can follow what competitive players actually pick.
- Live damage meter: Track your damage per turn, total, biggest hit, and damage taken in combat. Drag it anywhere on screen.
- Personal insights: Your own pick rates and run history shown alongside the community stats.
- Map route & danger: A recommended route plus per-node danger ratings from community data (Codex Risk).
- In-overlay settings: Toggle every on-screen surface and pick your stat bracket right from the F5 panel.
- Localized in 14 languages: The whole mod follows your game's language automatically, including card, relic, potion, monster, and character names.

- Open/close the overlay: F5 (or click either stick, R3/L3, on a controller)
- Switch tabs: Tab (or L1/R1 / LB/RB on a controller)
