How to Destroy Bedrock Keys

Shoot Geogranum's at the Bedrock Key

To destroy Bedrock keys, you'll need to use Cage-Shaped Geo formations to fire a Geogranum and activate it.

1. Destroy a Geogranum ore and take it to the Cage-Shaped Geo formation.
2. While facing the Bedrock Key, hit the Cage-Shaped Geo Formation with a Normal Attack.
3. Activate all Cage-Shaped Geo Formations from highest to lowest.

Use a Geogranum to a Cage-Shaped Geo Formation

Destroying a Geogranum Ore will release a Geograna that will follow your character. Bringing it to the Cage-Shaped Geo Formation will activate it, allowing you to hit it.
