Vault of Glass is a Raid located on Venus, located in the Vex structure of the same name. It was made available in Destiny on September 16, 2014, and is one of the four Raids in the game. A reprised version of the Raid was released in Destiny 2 on May 22, 2021.

How do you unlock the vault of glass in Diablo 2?

To access the Vault, players must activate three Vex plates outside its front door, and keep them activated continuously for five minutes. This builds a spire in the middle of the area, which unlocks the gate. If any of the plates become deactivated, the spire will rapidly disassemble.
