Galvantula

Compound Eyes : This Pokémon's moves have 1.3× their accuracy. This ability has no effect on the one-hit KO moves (fissure, guillotine, horn drill, and sheer cold). Overworld: If the first Pokémon in the party has this ability, the chance of a wild Pokémon holding a particular item is raised from 50%, 5%, or 1% to 60%, 20%, or 5%, respectively.

Unnerve : Opposing Pokémon cannot eat held Berries while this Pokémon is in battle. Affected Pokémon can still use bug bite or pluck to eat a target's Berry.

Swarm : When this Pokémon has 1/3 or less of its HP remaining, its bug-type moves inflict 1.5× as much regular damage. Overworld: If the lead Pokémon has this ability, the wild encounter rate is increased.
