Stats & Training
Nothing fancy in Gastly's spread. It leans special with Sp. Atk out front. And you'll get 1 Sp. Atk EV per KO for it. Follows a 1.06M XP medium-slow curve.
With its gas-like body, it can sneak into any place it desires. However, it can be blown away by wind.
Its body is made of gas. Despite lacking substance, it can envelop an opponent of any size and cause suffocation.
Gastly Weakness
Gastly is weak to Ground, Psychic, Ghost, and Dark. On the flip side, it's immune to Normal and Fighting-type moves entirely. Levitate grants an additional Ground immunity, reshaping the matchup chart. Gastly leans toward special offense (base 100 Sp.Atk) instead of trying to wall anything.
