When used from the Bag in the overworld, it increases encounter rates of rarer wild Pokémon, including Shiny Pokémon, for 200 steps. It also causes all wild Pokémon spawned to have a level 1 greater than the highest level normally in the area (for example, if an area's wild Pokémon normally range from level 3 to level 5, all wild Pokémon will be level 6 instead).
