Basics
Koffing is a Poison-type Pokémon. Its 100% IV CP is 694 at level 20 (raids, eggs and research), 867 at weather-boosted level 25 and up to 1,373 at level 50. It is weak to Ground/Psychic attacks (1.6×). It resists Grass/Fighting/Poison/Bug/Fairy attacks. In raids, Acid + Sludge Bomb is its strongest moveset (level 40, 100% IVs). It evolves into Weezing with 50 Candy. As your buddy, it earns 1 Candy every 3 km you walk together.
