Card Rewards Helper connects your game to ststracker.app, a community stats platform for Slay the Spire 2. It provides real-time recommendations based on aggregate win rate data from thousands of uploaded runs.
Card Scoring — When you're offered cards after combat, in events, or at the shop, the mod scores each option and displays a color-coded badge beneath the card. Hover over a badge to see a detailed breakdown: Card base score, synergy with your current cards, copy count impact, and upgrade value.
Ancient Choice Scoring — At the start of each act, Ancient blessings show win rate and pick rate stats for each option, filtered by your character.
Shop Relic & Potion Scoring — Relics in the shop display win rate delta (how much owning this relic correlates with winning). Potions show pick rate (how often players pick this potion when offered).
Auto-Upload — Completed runs are automatically uploaded to your STS Tracker profile.
Active Run Sync — Your current run syncs to the browser companion page in real-time.
1. Extract the StsCompanion folder into your STS2 mods directory: C:/Program Files (x86)/Steam/steamapps/common/Slay the Spire 2/mods/
2. Go to ststracker.app, log in and generate an API token in Settings
3. Open sts_companion_config.cfg inside the mod folder and paste your token into the apiToken field
{
"apiToken": "sts_gasd43423dfhsdlfkhfh", <-- your api token goes here
"apiUrl": "https://ststracker.app",
"overlayEnabled": true,
"autoUploadRuns": true,
"syncActiveRun": true,
"badgeScale": 1.0,
"tooltipScale": 1.0,
"proMode": false
}
4. Launch the game — the mod loads automatically
If you're using rusty-sts for auto-sync, disable it to avoid duplicate uploads. Use one or the other, not both.
Recommended mods:
UnifiedSavePath - if you want to keep same progress for vanilla/modded play as by default modded games are saved separately.
ModConfig - allows to change config directly in game (you still need to add API key manually into the config file)
Features:
- In-game card ratings on post-combat rewards, event card choices, and shop cards
- Ancient choice (Pael's blessing) win rate and pick rate scoring
- Shop relic win rate correlation and potion pick rate scoring
- Color-coded scores: green (strong), yellow (average), red (weak), gold border on best pick
- Hover tooltips with 5-factor score breakdown (baseline, archetype, synergy, copies, upgrade)
- Automatic upload of completed runs to your STS Tracker profile
- Active run sync to the browser companion page in real-time
- Configurable: toggle overlay, auto-upload, and active run sync independently
- NEW - "pro player" feature which only suggests you cards from A10 runs of high winrate players

StsCompanion and STS Tracker is a passion project I build and maintain in my free time. If you find it useful and want to help keep it running, you can buy me a coffee. It helps cover server costs and lets me spend more time adding new features. Thank you for your support!
