Orb of Frozen Souls
An orb of frozen souls is an item that can be used to spawn Articuno. To do so, the orb needs to be charged by defeating 375 Pokémon with the orb in the player's inventory and then used on a frozen shrine. The Pokémon do not have to be Ice or Water-type Pokémon. The remaining number of Pokémon to defeat can be displayed by using the orb.
