This guide breaks down a fast, repeatable Tier 16 City Square strategy built around two things: spawning extra Maven invitation bosses for Maven Chisels, and stacking Delirium reward types for bulk Delirium Orb payouts. The goal is stability: consistent sellable drops per map, short clear times, and minimal reliance on jackpot uniques. You’ll learn the exact mapping setup (8-mod City Squares, scarabs, map device choice), the Atlas priorities that add monster density without slowing you down, and a clean route through the map so you reliably hit high Delirium reward tiers.

Because this method leans on dangerous invitations and juiced 8-mod T16s, it’s best for characters that can handle most map mods and can comfortably kill the hardest Maven invitation encounters. When it’s running smoothly, it converts time into liquid items you can sell quickly, which also makes it a good way to fund upgrades with PoE currency rather than waiting on rare drops.

What the strategy is (and why it’s stable)

The core loop is simple:

• Run T16 City Square maps that are corrupted 8-mod and high quantity.
• Force extra bosses from a random Maven invitation inside the map via a boss-focused scarab.
• Apply heavy Delirium reward scaling using multiple Delirium scarabs that add reward types.
• Cash out two main outputs: Maven Chisels from the invitation bosses and Delirium Orbs from the Delirium reward track.
• Use the Mirage NPC payout at the end of Delirium, and sometimes re-kill invitation bosses inside the Mirage arena for additional chisel drops.

Compared to more RNG-heavy farms, this one is stable because a large portion of value comes from repeatable, high-volume commodities. In many economies, Delirium Orbs remain highly liquid, and Maven-related currencies sell quickly because they’re used constantly for mapping and endgame prep.

Prerequisites: build requirements and expectations

Before investing in scarabs and bulk maps, make sure your character can do the following reliably:

• Clear T16 8-mod maps without bricking on common mod combinations.
• Kill tanky invitation bosses quickly enough to maintain Delirium reward momentum.
• Survive stacked rare/magic packs (shrines, ritual spawns, altar monsters) under Delirium pressure.
• Handle high incoming damage spikes while moving fast (you’re aiming for roughly 2–3 minutes per map).

A practical benchmark: if you can comfortably complete The Feared invitation, you typically have enough damage and defenses to run this farm without constant deaths or time loss.

Map choice: why City Square works

City Square is ideal here for three reasons:

• Fast routing: the layout is simple and compact, which helps maintain Delirium stacks.
• Central boss access: it’s easy to include the map bosses in your route to push reward tiers.
• Consistent density scaling: added packs from Atlas mechanics are easy to pick up without detours.

Other maps can work, but City Square’s “corners then center” flow is especially good for quickly finding spawned invitation bosses while still finishing on the map bosses to add another reward tier.

Buying and preparing your maps (8-mod, high quantity)

You want corrupted, 8-mod T16 City Squares with strong item quantity. A practical target is around 110%+ quantity per map, though higher is better if your build can handle the mods.

How to source maps efficiently

• Use trade filters for: T16 City Square, corrupted, and minimum quantity.
• Bulk-buy to reduce downtime and keep your per-hour rate consistent.
• Reject maps with mods that hard-counter your build (for example, reflect for many hit-based builds, or no regen for certain sustain setups).

This is one of the spots where having a cushion of orbs and resources matters. If you’re trying to sustain a high-roll mapping loop early, having spare funds for bulk 8-mods and scarabs prevents the farm from stalling while you re-stock.

The baseline setup per map is:

• 1x Horned Scarab of Awakening (or equivalent that adds bosses from a random Maven invitation)
• 4x Delirium Scarab of Paranoia (to add multiple additional reward types)
• Delirium enabled so you can build reward layers and cash out at the end

In addition, apply Delirium-related map items (commonly referred to as “astrolabes” in some communities) that increase Delirium rewards. The exact naming and availability can vary by league economy, but the concept is consistent: you’re paying extra to make the Delirium track and end payout significantly larger.

Why four Paranoia scarabs?

This strategy leans on the fact that adding reward types increases the quantity of Delirium Orbs you receive at the end. In many league economies, Delirium Orbs can be priced high due to popular mapping metas that consume them in bulk. When that demand is present, the farm becomes extremely liquid: you finish a map, end Delirium, and immediately have sellable items.

Atlas tree priorities (density without detours)

The Atlas goal is to spawn more monsters and more valuable monster types while keeping your pathing clean. The priorities below mirror the core idea: pack size and rare/magic density matter more than side-mechanics that slow you down.

1) Ritual nodes for monsters (but don’t run Ritual)

Take Ritual passives that increase Ritual presence and spawns, but do not activate the Ritual altars. The spawned monsters still exist and still feed Delirium rewards and drops, without forcing you into a stop-and-stand mechanic.

2) Shrine nodes for more rare and magic monsters

Shrines are efficient in this setup because they add monsters and can speed you up with buffs. Again, the theme is density and tempo.

3) Delirium passives that improve reward scaling

Prioritize nodes that increase Delirium effectiveness for mapping and reward progression. Avoid passives that push you toward low-value reward types if your market doesn’t support them.

One common optimization is skipping nodes that heavily bias toward Cluster Jewel rewards or extra Simulacrum splinters if those returns are weak in your economy. The strategy is already producing sellable Delirium Orbs; you’re trying to avoid diluting the payout with slower-to-sell items.

Extra item quantity is especially valuable here because it scales the value of your Maven chisel drops and improves general returns. If you’re running Searing Exarch influence, altars can also spawn additional monsters immediately, which helps keep Delirium reward layers climbing.

When choosing altar options, prioritize quantity when it’s offered in a way your build can tolerate. Quantity tends to be the most broadly useful choice in a farm that already produces a lot of raw sellable items.

5) Map sustain and consistency tools

If your Atlas has access to passives that improve sustain and reduce the chance of “ruining” your repeat mapping loop, take them. The point is to be able to chain City Squares back-to-back without constantly rebuilding your setup.

In-map routing: the 2-minute City Square clear pattern

Your execution matters as much as your setup. The cleanest route is:

• Start Delirium immediately so reward layers begin tracking.
• Clear the corners first to quickly locate spawned invitation bosses and pick up dense packs.
• Click altars when safe, prioritizing quantity options that don’t brick your defenses.
• Finish in the center by killing the City Square bosses to add another Delirium reward layer.
• End Delirium at the Mirage NPC to receive your Delirium Orb payout.

The “corners first” approach is important because it reduces backtracking. Backtracking is the silent killer of this farm: it lowers Delirium reward progression and reduces your maps-per-hour, which is where most profit actually comes from.

How many Delirium reward layers should you aim for?

A consistent target is to fill a high number of reward layers each map (many runners aim around 6–7 when things go well). The exact number depends on build speed and how quickly you find invitation bosses, but the principle is constant: keep moving, keep killing, and avoid mechanics that pause your clear.

Mirage NPC arena: the bonus that pushes profit higher

After you end Delirium, you’ll sometimes get access to a Mirage arena. When this happens, the key benefit is the chance to fight invitation bosses again inside the Mirage area.

• If the spawned invitation bosses are present in the Mirage arena, you can effectively double-dip on chisel drops.
• If you don’t get the right bosses in the Mirage area, the map can still be profitable because your baseline Delirium Orb payout remains strong.

Think of Mirage as a multiplier on an already stable baseline rather than the sole reason the strategy works.

Loot breakdown: what you’re actually selling

These are the backbone of the strategy. They drop from the extra invitation bosses added to your map. Some chisel variants can be considerably more valuable than others, but even the “average” chisel volume adds up quickly when you’re running many maps per hour.

Delirium Orbs

The second pillar of profit is the Delirium Orb payout from the end-of-Delirium reward track. In metas where Delirium Orbs are in high demand, this becomes one of the fastest-to-liquidate outputs in the game.

Incidental raw drops

You will also see raw currency and random valuable items. These are not the foundation of the method, but they help smooth variance. Treat big drops as upside, not as something you need to “make the farm work.”

Investment and profit math: how to evaluate your own results

To judge this strategy fairly, track it like a business:

• Record your per-map cost: scarabs, Delirium enhancers, and the map itself.
• Record your liquid returns: Maven chisels and Delirium Orbs first, then everything else.
• Track maps-per-hour. A slower run can look good per map but lose badly per hour.

A common pattern is that even a “bad” map where Mirage doesn’t cooperate can still return enough sellable items to beat the per-map investment. Your best maps are the ones where you hit strong Delirium layers, kill invitation bosses quickly, and then re-kill them in Mirage.

If you’re funding this in the first week of a league, keep a reserve for re-stocking consumables. That’s where league start PoE currency planning matters: the farm is strongest when you can buy in bulk and keep your mapping loop uninterrupted.

Common mistakes that kill the farm

• Running slow layouts: if you switch off City Square, make sure the replacement is equally fast and boss-accessible.
• Over-investing into side mechanics: anything that makes you stop (or backtrack) reduces Delirium layers and maps-per-hour.
• Bricking maps with mods you can’t run: 8-mod is only good if you can actually clear it.
• Chasing low-value Delirium rewards: if a reward type is weak in your economy, don’t bias into it.
• Not prioritizing quantity from altars: when safe, quantity improves the exact items you’re farming.

When to scale up (and when to stop)

Scale up when:

• You can maintain a consistent clear time.
• You have enough bulk supplies to run 30–50 maps without re-buying.
• Your market can absorb large stacks of Delirium Orbs and Maven chisels quickly.

Consider stopping or pivoting when:

• Delirium Orb prices crash due to meta shifts.
• Your build starts dying frequently in 8-mod maps (death resets tempo and profits).
• The cost of scarabs rises faster than the sale value of your main outputs.

For players who prefer a smoother gearing curve, it can be worth converting a portion of proceeds into upgrades immediately rather than hoarding. Whether you’re crafting, trading, or occasionally choosing to buy Path of Exile currency to skip a re-stock bottleneck, the important part is keeping the mapping engine running.

Do I need to actually complete Rituals for this strategy?

No. The point of Ritual passives here is monster density. You kill the monsters Ritual spawns but skip activating the altars to keep your clear fast.

What’s the biggest requirement for making City Square Delirium feel consistent?

Speed and survivability under pressure. If you can’t keep killing while moving, your Delirium reward layers will stall and your per-hour return will drop.

Is this viable if I can’t run every Maven invitation?

It’s risky. The extra invitation bosses are a core profit source, and failing those encounters costs time and momentum. Aim to be strong enough for the hardest invitations before going all-in.

What should I sell first to get my investment back quickly?

Start with the most liquid outputs: Delirium Orbs and Maven chisels. Treat everything else as bonus. This is especially helpful if you’re managing endgame PoE currency needs for upgrades and scarab re-stocking.

How do I avoid running out of supplies mid-session?

Buy maps and scarabs in bulk, and track your average cost per map. If you’re short on reserves, consider lighter investment until you rebuild. Some players also look for the best site to buy cheap PoE currency with fast delivery to smooth out early-league supply gaps, but the core fix is always better planning and bulk purchasing.
