The Reveal Glass is a Key Item in Pokémon Legends: Arceus needed to transform certain legendary Pokémon into new forms. Although, finding this item will have to wait until the postgame.

Doing this helps the local residents get a better understanding of the local Pokémon and their habits. It also unlocks new areas, crafting materials, and requests around the Hisui region.

The item does make a return in Pokémon Legends: Arceus due to the debut of a fourth member to this group, Enamorus. It also has its own Therian and Incarnate forms to change between.
