The user of Dig will
burrow its way underground on the first turn, disappearing from view and becoming invulnerable to most attacks. On the second turn, Dig deals damage.
While underground, the Pokemon can only be hit by the moves Earthquake, Magnitude or Fissure, with Earthquake and Magnitude dealing twice normal damage. Moves from No Guard Pokemon, or any move following an
identify move can also hit for regular power. The user also avoids end-of-turn damage from Sandstorm and Hail when underground.
If the user is holding a Power Herb, Dig executes in one turn.
