✨ Keen Eye | Gen 4
Effect:
This Pokémon cannot have its accuracy lowered. This ability does not prevent any accuracy losses other than stat modifiers, such as the accuracy cut from fog. It also doesn't prevent other Pokémon's evasion from making this Pokémon's moves less accurate.
Effect Outside Battle:
If the first Pokémon in the party has this ability, any random encounter with a Pokémon five or more levels lower than it has a 50% chance of being skipped.
