📋 About This Mod
Description:
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.
Installation instructions:
1. Extract the StsCompanion folder into your STS2 mods directory: C:/Program Files (x86)/Steam/steamapps/common/Slay the Spire 2/mods/
