Scope Lens

The only way to obtain a Scope Lens is by trading for one at the Battle Maison’s Exchange Service Corner. Each Scope Lens costs 48 Battle Points (BP) and you can get multiple copies this way.

The Battle Maison facility is situated at the Battle Resort, an island which only becomes accessible after completing the Delta Episode in the post-game.

Uses

The Scope Lens is a held item that boosts the Critical-Hit Ratio of the holder’s moves by one stage. This means that any attacking move used by the holder has a higher chance of landing a Critical Hit.

Landing a Critical Hit boosts damage by 50%. Additionally, Critical Hits ignore the attacker’s negative stat stages and the defender’s positive stat stages, making it extremely useful in battle.

Critical Hit probability is calculated in stages, with each stage increasing the chances of landing one.

Most attacking moves will begin at Stage 0 – but with a Scope Lens, all the holder’s moves begin at Stage 1. The stages and their chances of landing a Critical Hit are listed below:

Pokémon that can learn high Critical-Hit Ratio moves like Leaf Blade, Psycho Cut, or Shadow Claw can benefit greatly from holding a Scope Lens. When paired with these moves, the Scope Lens boosts the chances of a Critical Hit even further.

But keep in mind that while this held item can make landing Critical Hits easier, the Scope Lens still relies heavily on luck, – which makes it potentially unreliable in competitive play.

Most players often prefer using items that provide consistent boosts, such as the Life Orb or Choice Band.

Scope Lens + Super Luck

You can pair the Scope Lens with the Super Luck ability to further increase the Critical-Hit Ratio of moves by one extra stage.

A Pokémon with Super Luck and a Scope Lens will start with a Stage 2 Critical-Hit Ratio, resulting in a 50% chance to land a Critical Hit. And if the Pokémon also uses a high Crit-Ratio move, it will always land a Critical Hit!

Here is a list of all Pokémon with the Super Luck ability:
