Stats & Training
Defense and Attack carry most of Koffing's stat budget. Speed's the obvious dump stat. Common in the wild and yields 1 Defense stat exp. Follows a medium-fast 1M XP curve.
Its thin, filmy body is filled with gases that cause constant sniffles, coughs and teary eyes.
The poisonous gases it contains are a little bit lighter than air, keeping it slightly airborne.
Koffing Weakness
Ground and Psychic moves hit Koffing for super-effective damage. 4 resistances help offset the weaknesses. Koffing's physical bulk (base 95 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |

| 0.5x (Resist) | Grass, Fighting, Poison, Bug |
