WIP Damage Calculator
Compute damage with Polished integer rounding, STAB/type/weather, and 85–100 variance.
Knowing exact damage ranges helps you make critical battle decisions: can you survive a hit and KO back? Should you switch or stay in? Polished Crystal uses Gen 2-style integer rounding, which affects damage differently than modern games - small differences in stats can change KO thresholds.
Damage has an 85–100% random variance, meaning the same attack can roll different outcomes. This calculator shows min/max damage to help you plan for worst-case scenarios. Understanding OHKO (one-hit KO) vs 2HKO probabilities is crucial for competitive play - always account for critical hits, weather boosts, and held items like Life Orb or Choice Band.
When enabled, allows more than 508 total EVs per Pokemon (252 max per stat). Match this to your ROM configuration.
