How to Use Vault Key Fragments
Collect Three Fragments for Each Region
Three Vault Key Fragments found within a region combine into a complete Vault Key, which can then be used to open the Primordial Vault of that same region. Order Silos within the region can help reveal the general location of the remaining fragments.
Use the Vault Key at the Region's Vault Entrance
Combining all Vault Key Fragments allows you to enter the Primordial Vault within the region. The Vault's general location will be highlighted as you complete the Vault Key for it. Some Vaults require specific routes to reach, so watch for hidden paths that may lead to the entrance.
