The Complete Guide to Pokémon Dual-Type Effectiveness & Team Synergies
In competitive Pokémon battling across all generations, type matchups are the fundamental cornerstone of victory. Understanding how primary and secondary types interact—creating 4x quad-weaknesses or 0x immunities—allows trainers to predict switch-ins and seize momentum.
The Science of Dual-Type Defensive Multipliers
When a Pokémon possesses two types, defensive damage multipliers are calculated multiplicatively:
- 4x Quad Weakness: When both types share a 2x weakness (e.g., Grass/Steel taking 2x from Fire on Grass and 2x on Steel = 4x total damage).
- 0.25x Double Resistance: When both types resist an incoming attack (e.g., Steel/Flying resisting Grass = 0.25x damage).
- 0x Complete Immunity: Any type immunity overrides weaknesses (e.g., Ground/Flying is 100% immune to Electric despite Flying being weak to Electric).
