What We Publish

STS2Calc.com is an independent fan-made website focused on short, practical tools for decisions that happen during a run. We prioritize calculators and concise strategy notes over long database-style content.

  • Necrobinder Soul Calculator for lethal planning and damage thresholds
  • Regent Forge Estimator for rough forge tradeoffs and scaling checks
  • Draw Probability Calculator for deck-thinning and consistency checks
  • Co-op Synergy Checker for quick multiplayer pairing decisions

What We Do Not Claim

We are not the official Slay the Spire 2 website, not the official wiki, and not affiliated with Mega Crit. We do not claim access to private developer data or internal game systems.

Early Access patches can change mechanics quickly, so our tools should be used as planning aids. Players should always verify important interactions against the current in-game patch.

Editorial Approach

Our goal is to make the site useful for real gameplay decisions: should you thin the deck, can you reach lethal, does forge scale enough this fight, and which co-op pairing covers your weak spots. We keep pages focused, update copy when formulas or assumptions change, and avoid publishing placeholder pages as core landing pages.
