In Path of Exile 2, the Temple of Atziri is arguably the highest-ceiling mechanic in the game. However, it is also one of the most frustrating for beginners due to the dreaded Destabilization mechanic.

Thanks to a brilliant guide by community member Infinite-Ad5464, we now have a deterministic "engineering" approach to building a mega-dungeon. If you are tired of your rooms randomly disappearing, this guide is for you.

Why Build the Temple?

The Temple rewards scale multiplicatively.

• 10 Rooms: Barely worth running. Better off mapping.
• 30 Rooms: Loot becomes decent.
• 50+ Rooms: This is the goal. At this size, the Temple beats almost any other farming strategy. You will encounter hundreds of Rares with 25+ mods and massive rarity bonuses.

The Core Mechanics: Why Rooms Delete

To get new Room Cards, you must Close the Temple (costing 6 Crystals). However, closing the temple triggers Destabilization:

• The game deletes approximately 10% of your total rooms.
• It attempts to delete from the ENDS of chains.
• Crucial Logic: The system will NEVER create an "Island" (an isolated room disconnected from the start).

The Solution: The "Spymaster Chain"

The secret to preventing deletion is the Spymaster room.

• Lock Medallions: Spymaster rooms drop these medallions.
• The Effect: A locked room cannot be deleted.
• The Strategy: If you lock the last room in a long chain, the system cannot delete any room in that chain because doing so would turn your locked room into an "Island" (which is forbidden).

Infinite Leveling Strategy

How do you get rooms to Tier 3? Rooms level up when they interact or "consume" other rooms.

The Spymaster XP Trick:

• Spymasters level up by "killing" other Spymasters (when the game tries to delete them).
• The Hack: If you Lock a Spymaster at the end of a chain, the game tries to delete it, grants XP to the other Spymasters, but the room stays because it is locked.
• This allows you to farm infinite XP for your rooms without losing them.

Emergency Tips

1. No Lock? Pray to Atziri.
If you need to close the temple but haven't found a Lock Medallion yet, build a "buffer chain" of trash rooms on the opposite side of the map. The system will likely delete those instead of your precious Spymasters.

2. Kill The Architect.
Whenever you see The Architect in a map, kill him.

• Increases your Crystal Cap.
• Unlocks Medallion Slots (Max 6). You need these slots to hold more Locks.
• Forces him to respawn in a different location (good for layout planning).
