Most players meet Delirium in PoE 2 0.5.0 by spotting the Mirror near the map entrance, taking one step through it, and then realising the whole run has changed. The fog rolls out, monsters hit harder, and your route suddenly matters more than the pile of POE 2 Items waiting somewhere behind you. It's not just a loot event. It's a pace check. If you move well, kill fast, and don't panic, Delirium feels rewarding. If you stop every few seconds, it starts to feel like the map is pushing back.

The fog punishes bad habits

You'll notice it pretty quickly: Delirium doesn't like hesitation. Stopping to inspect every rare drop, ducking into awkward side rooms, or chasing one stubborn monster across the map can wreck the flow. The fog keeps asking you to go forward. Not recklessly, but with intent. A strong run usually looks simple. You enter the Mirror, choose a clean path, clear dense packs, grab rewards that are already on your line, and leave scraps behind. That sounds dull on paper, but in practice it's the difference between a smooth profit run and a messy death screen.

Shards are choices, not freebies

The new shard interactions make Delirium more interesting, though they also bait a lot of bad decisions. Purple shards raise the pressure by making enemies stronger while improving the rewards. Red shards pull you into a sealed arena, which can be great if you've got damage, recovery, and cooldowns ready. Fractured Mirrors bring extra waves, and they're usually worth touching when they're in a safe spot. The mistake is clicking everything just because it's there. Ask yourself a simple question before you commit: can my build handle the next thirty seconds? If the answer is shaky, keep moving. Pride is expensive in fog.

The road past normal mirrors

Delirium in 0.5.0 also has a clearer endgame path than before. Regular Mirrors can lead into Grand Mirror progression, where bosses may be duplicated and fights get much less forgiving. From there, players work toward the Trial of Madness and eventually the Simulacrum, the 15-wave arena built around Delirium splinters. That mode is where weak points show up fast. Maybe your mapper clears packs easily but melts when a boss appears. Maybe your boss killer has damage, but moves like it's carrying bricks. Delirium wants both sides of the character to work. Speed, damage, recovery, and enough defence to survive one ugly mistake.

Build for control, then get greedy

The best way to approach Delirium is to treat greed as something you earn during the run. Start clean. Watch how fast rares die. Check whether your flasks and recovery are keeping up. If everything feels stable, take the extra Mirror, break the shard, push the reward bar higher. If the map already feels rough, don't force it just because the reward icon looks tempting. Farming fog well is about rhythm, not hero moments, and players who prepare with solid gear, smart routes, and dependable POE 2 Items for sale options will usually get more out of Delirium than players who treat every encounter like a dare.
