STS2Calc Case Studies

Real gameplay scenarios analyzed with our tools. Each case study breaks down a specific decision moment — the wrong choice, the right choice, and the math that reveals the difference.

Why case studies matter

Tools are only useful if you know when to apply them. These case studies show how STS2Calc calculators transform specific gameplay moments — elite fights, shop decisions, boss phases — from "I think this is right" to "I know this is optimal."

What you'll learn from each case study

  • The scenario: Exact game state and decision moment
  • The calculation: Which tools to use and what inputs to enter
  • The result: Why one choice succeeds where another fails
  • The lesson: How to apply this to your own runs
