Temple help

Keep killing architect or start a new character

if you kill both arch and atziri that will nuke most of it

• Since you're close to the architect, path to him via your chain on the left that ends in Smithy, and beat the architect. This will destabilize roughly 30% of the rooms in your temple
• Afterwards, you can keep pathing to him to try to move him to the best min-max spot, which is 4 spots away from Atziri near the middle.
• Otherwise, don't place any other rooms, and complete rooms that can give you medallions for assistance in building when you finish nuking your temple. On your current temple, this includes GW, Smithy, Legion Barracks, Spymaster, Commander, and Alchemy Labs. You'll want to keep an eye out for Lock Medallions (can drop from Spymaster, t3 Legion Barracks, and t3 Smithy from what you have) and Room Medallions (t3 Spymaster, t3 Legion Barracks, Commander, Smithy, and Alch Labs can drop these from what you have)
• If you don't have any of the above rooms left, have full useful medallions, or don't feel like putting in any time to clear your temple as-is, then you can simply open a temple, enter, leave, and close it. It will destabilize roughtly 10% of your rooms when you close it. Keep in mind this means as you get closer to finishing nuking your temple and have less than 10 rooms, you will only destabilize 1 room at a time

What everyone else said with one addition - stock up on waystones and get as much %light radius gear as you can: gifts from above ring, guiding palm with a random light radius 1h weapon on swap + use swap passive skills to path to as many % light radius nodes as you can. This will make looking for crystals in map much faster and over the course of destroying current + building new temple it will save you probably hours if not tens of them
