The user will not switch out if Parting Shot fails (such as if it has no target), if the target is immune (such as due to Soundproof), or if it is blocked by a protection move. However, the user will switch even if Parting Shot is unable to affect the target's stats (such as due to Clear Body or Mist).
If Parting Shot is used on a Pokémon with the Ability Magic Bounce, the effect will be bounced back to the user, lowering its Attack and Special Attack, and the target will switch out instead.
If an opponent uses Pursuit on the same turn Parting Shot is used, Pursuit will deal normal damage if the foe is faster, or double damage if the foe is slower than the user.
The user no longer switches out if Parting Shot is unable to affect the target's stats (such as due to Clear Body or Mist); the user will no longer switch out if the target already has both -6 Attack and Special Attack stat stages (unless the target's Ability is Contrary, in which case the user will not switch out if the target has both +6 Attack and Special Attack stat stages).
If powered up by a Darkinium Z into Z-Parting Shot, if a Pokémon is switched in to replace the user the same turn, that Pokémon has its HP fully restored (even if Z-Parting Shot was not used successfully after gaining its Z-Power effect).
