The Temple board in PoE 2 Patch 0.4 can look like a mess the first time you stare at it, especially if you're chasing PoE 2 Currency and don't wanna waste a run on a bad layout. The key isn't "perfect rooms" right away, it's control. You're trying to stop the Temple from auto-growing into awkward branches that ruin your routes. Once you start thinking in locked lanes and safe corners, it gets way less stressful, and you'll make cleaner decisions under pressure.

Build the first neck and freeze the corners

Early on, keep your main lane simple. Rotate between Armory or Garrison and Spymaster as you extend forward. When you reach the first corner, place Spymaster, then Garrison, then another Armory or Garrison, and finish that corner with Spymaster. Then lock it. Don't "see what happens" next run. If you leave that corner open, the game loves to flip you into a dead end or a branch that steals your best slots. After that, mirror the same idea on the opposite side. Two stable corners means the Temple stops fighting you and starts behaving.

Weave in Alchemy and set up Corruption early

Once the spine is stable, start threading Alchemy rooms into the path. Most of the time you'll go Alchemy, then Sacrifice, then aim into the Corruption Chamber. The moment Corruption hits the board, lock it. Waiting even one step can create conflicting connections later, and you'll feel it when you try to extend the line and everything wants to fork. While you're building toward that, cycle your utility picks like Smithy and Golem so you're not stuck with filler rooms when it matters.

Clear blockers and protect your upgrade chain

You'll sometimes get an active room sitting exactly where you need Smithy or Golem. People try to play around it and "save" the room, and that's usually how the whole run collapses. Just delete the blocker. It's better to lose one mediocre room than lose your Corruption options or get forced into a useless branch. Drop Smithy and Golem where they belong, lock both, and keep the structure tight. To finish the first neck, a common clean line is Armory, double Alchemy, then Corruption—lock the Corruption slots instantly. If the board cooperates, you can even land two Corruption Chambers side-by-side, which is huge for farming value.

Keep the second line straight and don't fear bosses

The second lane should be boring on purpose: place your rooms in a straight shot, lock both ends, and don't let it branch. Keys and boss runs won't wreck your layout either—drop the key room, lock it, go kill the boss, come back, and your structure stays put. The only real "gotcha" is locking your entry connection and then ending the run without leaving yourself a restart point for the next placement. Double-check that before you exit. And if you're short on time and just wanna keep mapping, a lot of players top up gear or currency through U4GM so the Temple grind doesn't stall their builds.
