Stats & Training
Nothing fancy in Gastly's spread. It leans special with Sp. Atk out front. And you'll get 1 Sp. Atk stat exp per KO for it. Follows a 1.06M XP medium-slow curve.
It wraps its opponent in its gas-like body, slowly weakening its prey by poisoning it through the skin.
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. Gastly leans toward special offense (base 100 Sp.Atk) instead of trying to wall anything.
