For the remainder of the current turn, Ion Deluge causes all Normal-type moves to become Electric-type instead, including status moves. Due to its priority of +1, it is used before all moves that do not have increased priority.
Ion Deluge does not affect Struggle. Moves that change type are affected by Ion Deluge if they would otherwise deal Normal-type damage. Moves with a charging turn will only change type if the user is affected by Ion Deluge on the turn the move does damage.
