|10||%||Affects the user|
Protects the user from all effects of moves that target the user during the turn it is used, including damage (does not include damage from weather or a status ailment that it obtained on a previous turn). Also, if it blocks an attack that would make contact with the user, the attacker suffers damage equal to 1/8 of its max HP. If the foe uses Sucker Punch, the move fails and the Pokémon does not take damage. If an attack is blocked, the effects of the user's Rocky Helmet, Rough Skin, and Iron Barbs will not activate. Using Spiky Shield divides the chance of success of Protect, Detect, Endure, Spiky Shield, and King's Shield by 3 for each consecutive use. Feint, Phantom Force, Shadow Force, Hyperspace Hole, and Hyperspace Fury lift Spiky Shield's protection for the rest of the turn. It is unable to defend against the following moves: Acupressure, Aromatic Mist, Confide, Conversion 2, Curse, Doom Desire, Feint, Future Sight, Hyperspace Fury, Hyperspace Hole, Hold Hands, Perish Song, Phantom Force, Play Nice, Psych Up, Roar, Role Play, Shadow Force, Sketch, Transform, and Whirlwind.
