What these guides are
Each guide covers one vanilla Java Edition mechanic in depth — the formula, why it behaves the way it does, and how to work with it rather than around it. They're written to back up the calculators on this site, not replace them: read the guide to understand why a number comes out the way it does, then use the matching tool to run your own numbers.
