Understanding Matchups
A Pokémon battle often turns on one small multiplier. A strong attack can fail when the defender resists its type. A modest move can win when it strikes a double weakness. This calculator helps you study that hidden layer before choosing a move. It compares the attacking type against one or two defending types. It then applies optional battle rules, items, abilities, and field effects.
Why Weakness And Resistance Matter
Every type has fixed relationships with the other types. Fire is strong against Grass. Electric does not affect Ground. Ghost ignores Normal. Dual type Pokémon multiply both defensive answers together. A Water move against Rock and Ground becomes four times effective. A Fire move against Water and Dragon becomes one quarter effective. These values shape switching, coverage moves, raids, and team building.
Advanced Options
The extra options make the calculator more useful. Ring Target can remove a normal immunity. Gravity can let Ground moves hit Flying targets. Levitate can block Ground moves. Thick Fat can reduce Fire and Ice damage. Filter and similar abilities soften super effective hits. You can also add STAB, critical hits, weather, terrain, spread damage, burn, and a custom modifier. These settings turn a simple type chart into a planning tool.
Using The Damage Estimate
The damage estimate is not a full battle simulator. It uses the common damage structure with level, base power, attack, defense, random range, and selected modifiers. It is best for comparing choices. Try different attacks and defender types. Then compare the final multiplier and damage range. A lower base power move may still win when its type advantage is better.
Practical Battle Planning
Use this page before raids, friendly matches, or team edits. Test your main coverage attacks first. Then check common threats. Look for types that resist your whole moveset. Add a second attack type to cover those gaps. Keep notes from the result summary. Export the report when you need a quick matchup reference. Good planning saves turns. It also helps you avoid wasted attacks during close battles. For best results, enter realistic stats. Change one option at a time. This keeps comparisons clear. Save exports after important tests for future team reviews during ranked match preparation.
