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 EV. Follows a medium-fast 1M XP curve.
Getting up close to a KOFFING will give you a chance to observe, through its thin skin, the toxic gases swirling inside. It blows up at the slightest stimulation.
Koffing Weakness
Ground and Psychic moves hit Koffing for super-effective damage. 4 resistances help offset the weaknesses. Levitate grants an additional Ground immunity, reshaping the matchup chart. Koffing's physical bulk (base 95 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
