Scope Lens

Raises critical hit ratio by one stage. (Hold)

Scope Lens increases your critical hit rate by one stage, which stacks with high-crit moves for more consistent crits. Unlike Razor Claw, it doesn't have an evolution use, so this is purely a battle item!

This works best on Pokémon with moves like Slash, Night Slash, or other increased-crit moves. With Super Luck as an ability plus Scope Lens plus a high-crit move, you can get near-guaranteed criticals every attack. It's a bit niche but very satisfying when it all comes together!
