How can Pokemon learn Draco meteor in Pokemon diamond?

Answer 1

Go from Solaceon town on route 210. Look for where the fog is, and go to the corner-like place of the map and look for a little house. There's a tutor that teaches Draco meteor.

You have to have a pokemon with high friendship, with 2 hearts on the friendship checker app.

A good idea is to have all physical attack moves, since Draco meteor only decreases Sp. Attack. You should also only use it if it's going to make the enemy faint.
