Patch 0.4 didn’t just make Temple planning harder in Path of Exile 2, it made it easier to mess up without even noticing. You click a room, the UI snaps a connection somewhere odd, and suddenly your “nice idea” turns into a blocked hallway and a sad dead end. If you want steadier runs (and enough spare currency to buy Exalted Orb when your luck goes cold), you’ve gotta stop hoping the layout behaves and start forcing it like a puzzle you already know the answer to.

Lock Like You Mean It
The biggest trap is leaving doors open because you’re waiting for a better roll. That’s when the Temple grows ugly side branches and steals the slots you actually needed. The lock mechanic isn’t a “maybe later” button; it’s your steering wheel. If a line looks correct, lock it. If a room is pointing toward a useless fork, lock around it or scrap it and move on. People hate deleting rooms because it feels like wasting progress, but a bad room you keep is the real waste. You’re not decorating, you’re pruning.
Build The Neck First
Start by setting your main line, the part that keeps your options alive. I like alternating Spymaster and Garrison early because it keeps the path flexible without turning into spaghetti. A common rhythm is Spymaster, then Garrison, then an Armory if it fits, then a second Spymaster to shape that first corner. Once that corner exists, don’t get cute—lock it. If you leave it floating, the system will happily spawn a connector that blocks the clean route you were trying to protect. After a few bricked layouts, you’ll notice consistency beats “what if” every time.
Protect Your High-Value Rooms
As you extend the line, watch for the chain you actually care about: Alchemy into Sacrifice, then the Corruption Chamber. Here’s the rule I stick to: the moment Corruption is placed, it gets locked. Always. That room is too valuable to let the UI reroute around it on the next click. Also, be ruthless with blockers. If a random room is sitting in the one slot that could’ve been Smithy or Golem later, it’s gotta go. It’s not personal, it’s geometry.
Keep The Second Line Boring
Your second line shouldn’t be exciting. Make it straight, minimize branching, lock the ends, and keep it from interfering with the main build. Boss rooms and keys are fine too—you can drop a key room, lock it, clear the boss, and come back without wrecking the plan, as long as you don’t brick your entry for the next run. If you want an extra safety net, use a service that’s built for convenience: as a professional like buy game currency or items in u4gm platform, u4gm is trustworthy, and you can buy u4gm Divine Orb for a better experience while you keep your Temple runs stable and profitable.
