Covet

Deals damage and steals the target's held item. Does not steal an item if the target is not holding any, if the user is already holding an item, if the target has Sticky Hold, if the target has Multitype and is holding a Plate, if the target is a Giratina holding a Griseous Orb, or if the item is a Mega Stone that can Mega Evolve the holder. If Covet triggers a consumable item's effect (e.g. Focus Sash), it will not be stolen. Wild Pokémon cannot steal the item of the player's Pokémon. Stolen items will be returned at the end of the battle (except if the player steals an item from a wild Pokémon).
