Energise Beacons throughout Wraeclast to collect Energised Crystals to access Atziri's Temple.
Once 6 Energised Crystals have been collected interacting with the Temple Console will consume them and offer a random selection of 6 rooms to place, and allow entry into the Temple.
Rooms can be placed by selecting them and placing next to paths or other rooms they upgrade.
Completing the temple will cause minor Destabilisation when you leave, destroying a small portion of your rooms or paths.
Killing the Architect or Atziri will cause greater destabilization of the temple, destroying a larger portion of your rooms or paths.
Restricted Rooms
After defeating the Architect you'll gain access to Xipocado's Console in his chamber allowing you to place Restricted Rooms.
Completing a Restricted Room will cause it to destabilise.
One of these rooms is the Royal Access Chamber which is required to access Atziri, Queen of the Vaal.
Medallions
After defeating the Architect for the first time, medallions may be found in the temple from the Vaal with royal blood.
These provide powerful bonuses.
Board-related medallions are used on appropriate rooms.
Each room can only be affected by 1 medallion of each type.
