If there is a sandstorm what type of pokemon can get raised sp.df?

Question

Is it steel type, any type that does not get hurt by it, or just every pokemon.

Answer 1

Actually it is only Rock types.

Steel, Rock and Ground do not take damage from Sandstorm, but only Rock has their special defense raised by 50%.

Comments

Also note that Cacturne doesn't take damage either.
