Key System: Difference between revisions

A mysterious door in [[Clay Tunnel]] gives access to the [[Underground Ruins]], where the [[legendary golems]] can be found, though only one golem will appear at a time, depending on which key is active. {{p|Regirock}} is the default Pokémon in both Black 2 and White 2, under the '''Rock Peak Key'''. Upon catching Regirock, and not just defeating it or obtaining it from another game, Black 2 players are rewarded with the '''Iron Key''' and White 2 players with the '''Iceberg Key'''; these allow access to {{p|Registeel}} and {{p|Regice}}, respectively.

While Registeel and Regice are exclusive to Black 2 and White 2 respectively, players of the opposite version games can obtain their final legendary golem by transferring the appropriate key through the Unova Link.
