STS2Calc FAQ
Straight answers for climbers deciding between tools, wikis, and guesswork.
What is STS2Calc?
STS2Calc (sts2calc.com) is an independent fan site focused on Slay the Spire 2 calculators and decision tools — soul damage, forge simulation, draw odds, and co-op pairing. We are not a full wiki replacement.
How is this different from sts2-wiki?
Wiki sites excel at browsing cards, relics, and databases. STS2Calc is built for mid-run math and planning: “Will I draw X?”, “Is this soul stack lethal?”, “Is forge worth it this combat?” Use both: wiki for lookup, calc for decisions.
Is STS2Calc official?
No. We are not affiliated with Mega Crit. Always verify mechanics after patches; Early Access balance changes frequently.
Which calculator should I open first?
New players: Draw Probability for deck-thinning decisions. Necrobinder mains: Soul Calculator. Regent mains: Forge Simulator. Co-op groups: Synergy checker.
Do the tools use live game data?
Tools use the numbers you enter. They do not scrape private game servers. Update inputs when patches change formulas or card text.
Where can I play Slay the Spire 2?
On the official Steam store page for Slay the Spire 2. STS2Calc does not host the game client.
