PoE 2 The Third Edict Act 4 Boss Guide - Strategies and Tips

If you’ve made it to Act 4 in Path of Exile 2: The Third Edict, then you already know the game doesn’t hold your hand. The bosses here are brutal, mechanical, and punishing if you’re not prepared. This isn’t just a gear check—it’s a skill check. Having a solid grasp of each fight’s mechanics can be the difference between breezing through or wiping repeatedly.

Before diving into the fights themselves, let me throw in a veteran tip. Boss fights are always easier when you’re well-geared. And if you don’t have the patience to grind endlessly, there’s nothing wrong with giving yourself an edge. Sites like PVPBank are handy if you want to buy poe 2 currency quickly and safely to get the gear you need before these tough encounters. Just don’t forget: mechanics > gear.

Now let’s break down every boss fight in Act 4, step by step.

General Tips for Act 4 Bosses

Act 4 bosses in PoE 2 ramp up in complexity compared to earlier acts. Expect:

• Multi-phase fights that change tactics mid-battle

• Heavy damage-over-time mechanics

• Arena hazards that punish bad positioning

• DPS checks to ensure your build is on track

The key is staying calm, reading patterns, and pacing your flask usage. Don’t panic, and don’t tunnel vision DPS.

Boss 1: The Furnace Keeper

The first boss of Act 4, The Furnace Keeper, is essentially a test of movement and awareness. The arena is full of fire vents that activate in cycles, and standing in the wrong spot for even a second can shred your health.

Key Mechanics:

• Fire vent waves sweep across the arena

• Heavy melee cleaves that hit in a frontal cone

• Summons molten constructs mid-fight

Strategy:
Always stay mobile. Learn the rhythm of the fire vents—they’re predictable once you pay attention. Focus down the constructs when they appear because they’ll flood the arena with fire patches otherwise.

Boss 2: The Sand Wraith

The Sand Wraith introduces environmental hazards and visibility tricks. It constantly burrows underground, leaving you guessing where it will pop up next.

Key Mechanics:

• Burrow-and-strike attacks

• Summons swarms of smaller adds

• Sandstorm arena phases that obscure visibility

Strategy:
Keep moving in a circle to bait its underground charge. Use AoE to clear swarms quickly or you’ll get overwhelmed. When the sandstorm activates, hug the edges of the arena and listen closely for audio cues—sound can guide you when vision fails.

Boss 3: The Colossus of Chains

This fight is all about positioning. The Colossus drags you around with chain mechanics, and if you don’t react fast, you’ll get pulled into environmental hazards.

Key Mechanics:

• Chain pull into spiked walls

• Ground slams with massive AoE

• Periodic shield phases

Strategy:
When the Colossus casts his chain pull, immediately dash or blink to safety. Save your mobility skills specifically for this mechanic. During shield phases, ignore the boss and burn down his summoned totems—they’re the key to breaking the shield.

Boss 4: Mistress of the Veil

Mistress of the Veil tests your reaction speed. She alternates between ranged magic attacks and teleport slashes.

Key Mechanics:

• High burst magic damage

• Teleportation slashes from off-screen

• Summoned mirrors that duplicate her attacks

Strategy:
Always assume she’s about to teleport and never stand still. Focus on destroying the mirrors fast; the longer they stay, the harder the fight gets. Builds with strong single-target burst will shine here.

Boss 5: The Twin Serpents

One of the hardest fights in Act 4, the Twin Serpents are a tag-team duo that force you to manage two bosses at once.

Key Mechanics:

• Two bosses sharing a health pool

• Poison pools across the arena

• Split-phase where they attack separately

Strategy:
Keep the serpents close together to maximize your AoE. During their split phase, focus on dodging more than dealing damage—they become extremely aggressive. Antidote flasks are lifesavers here, don’t go in without them.

Boss 6: High Inquisitor Maltheris

This is the “gear check” fight of Act 4. Maltheris hits hard, heals himself if you fail mechanics, and punishes sloppy play.

Key Mechanics:

• Summons beams of light that heal him if he stands inside

• Fireball barrages with splash damage

• Phase shift with adds and traps

Strategy:
Always pull him out of healing zones. Positioning is everything here. When he summons adds, clear them quickly or they’ll overwhelm you. Builds with strong mobility will make this fight much easier.

Boss 7: The Shadow of Eternity

The final Act 4 boss, Shadow of Eternity, is a real endurance test. It has multiple phases and forces you to adapt constantly.

Key Mechanics:

• Phase 1: Shadow clones with dash attacks

• Phase 2: Arena-wide darkness where only small safe zones are lit

• Phase 3: Heavy-hitting ultimate ability with long wind-up

Strategy:
Clone phase: prioritize dodging over DPS. Darkness phase: stay in the light zones no matter what, it’s a survival check. Final phase: save your flasks and big cooldowns for when it channels its ultimate—you’ll need them.

Veteran Tips for Act 4 Bosses

• Don’t be afraid to overlevel before these fights. A few extra zones of grinding can save hours of frustration.

• Movement skills are worth their weight in gold here. If your build doesn’t have one, consider respeccing slightly.

• Flasks are not optional. Go in with a full set and make sure they’re quality.

• Learn patterns instead of brute forcing. These fights are designed around reading mechanics.

Final Thoughts

Act 4 of PoE 2 The Third Edict is where the game truly begins to separate the casuals from the veterans. The bosses here are designed to test not just your damage, but your patience, awareness, and adaptability. If you take your time to learn each mechanic, you’ll come out of this act stronger and better prepared for the endgame.

And remember, while skill is king, gearing properly will always make your life easier. If farming feels like a chore, you can always head over to PVPBank to safely buy poe 2 currency and give yourself that extra edge.

By mastering these fights, you’re not just beating Act 4—you’re proving you’re ready for what Path of Exile 2 has in store.
