Types & Matchups
The fundamental math of every battle — why Water douses Fire and when it doesn't.
The Type Chart in Plain English
Every Pokémon has one or two types. Every move has one type. When move type and target type interact, damage is multiplied by 0×, 0.5×, 1×, or 2×. Two weaknesses stack to 4×, which is usually game-ending.
The 6 Matchups You Must Memorise First
Water beats Fire/Ground/Rock. Grass beats Water/Ground/Rock. Fire beats Grass/Ice/Bug/Steel. Electric beats Water/Flying. Ground beats Electric/Fire/Poison/Rock/Steel. Fighting beats Normal/Ice/Rock/Dark/Steel.
Why STAB Matters
Same-Type Attack Bonus multiplies your damage by 1.5× when your move type matches your Pokémon's type. Always prefer STAB moves unless coverage solves a specific problem.
