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.
Its body is made of gas. Despite lacking substance, it can envelop an opponent of any size and cause suffocation.
Born from gases, anyone would faint if engulfed by its gaseous body, which contains poison.
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. The Ghost/Poison typing picks up 4 resistances to work with. 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.
