As you continue to explore the Kanto region in Pokémon Let’s Go, Pikachu! and Pokémon Let’s Go, Eevee! you can use Lures to attract more wild Pokémon spawns.
It’s an item that has been carried across from Pokémon GO and works in the opposite way to Repels. There are three Lure items that you can find that will last for different distances, whether that be the Lure (100 Steps), Super Lure (200 Steps) or Max Lure (250 Steps) – all available in your local Poké Mart as you progress further in the game.
When used, not only will they increase how many wild Pokémon spawn but they have additional bonuses. That improve chances that rare spawns will start to appear, and, along with that, Shiny Pokémon, too. And, as well as that, Lures can result in you encountering slightly stronger Pokémon, which means that those that you catch should be one level higher compared to normal.
