Path of Exile: How to Master Ascendancy Builds and Defeat Malachai

Path of Exile is a game that rewards planning, precision, and perseverance. Nowhere is that more evident than in two pivotal experiences: selecting your Ascendancy class and confronting Malachai, the final boss of Act 4. The first empowers your build with a new identity; the second pushes it to the breaking point.

This guide covers everything you need to know to successfully unlock and optimize your Ascendancy and bring down Malachai with confidence. Whether you're a new exile learning the ropes or a returning player refreshing your strategy, this walkthrough will help you dominate one of the most challenging parts of the early game.

Unlocking Your Ascendancy

Your journey toward power truly begins once you unlock your character's Ascendancy class. This specialized subclass adds game-changing passive skills that shape how you play.

To begin, you'll need to complete the Trials of Ascendancy scattered throughout Acts 1 to 4. These trials test your reflexes and awareness with deadly traps. Once you've completed all six, you can access the Normal Labyrinth from the Sarn Encampment in Act 3.

Inside the Labyrinth, you'll face more traps, puzzles, and Izaro—the boss of the Labyrinth. Defeating him completes the challenge and grants you your first two Ascendancy points, allowing you to select from three powerful subclasses unique to your main class.

Choosing the right Ascendancy depends on your build:

If you're slamming enemies up close, a Juggernaut or Slayer adds staying power.

For casters, an Elementalist or Inquisitor amplifies elemental or spell damage.

Summoner builds flourish under the Necromancer.

Ranged characters will thrive with Deadeye or Raider Ascendancies.

Once chosen, your Ascendancy opens a smaller skill tree tailored to your playstyle. As you progress through the game and complete harder versions of the Labyrinth, you'll earn additional points to strengthen your specialization.

Optimizing Your Build: Skills and Gear

An Ascendancy only reaches its full potential when paired with the right skill gems, support gems, and gear. Success against bosses like Malachai depends on efficient synergy between your character's offensive and defensive tools.

For example:

Spellcasters using Arc, Fireball, or Freezing Pulse benefit from supports like Spell Echo and Controlled Destruction.

Melee builds using Ground Slam, Earthquake, or Cyclone should link with Melee Physical Damage, Brutality, or Fortify.

Ranged bow builds work well with Rain of Arrows or Tornado Shot, supported by Added Cold Damage and Mirage Archer.

Your weapon should enhance your main skill type. Two-handed axes or maces are ideal for heavy melee builds. Wands, scepters, or daggers are preferred for casters. Bows are the natural fit for Rangers and projectile-based Duelists.

Early in the game, you'll often rely on rare and magic gear with decent stats. However, some unique items provide a significant advantage while leveling. Don't overlook useful crafting at your hideout's bench—it allows you to fine-tune resistances, life, and damage on your gear. Even a small boost to life or elemental resistance can mean the difference between life and death in a boss fight.

The right gear setup not only strengthens your damage output but prepares you for the survival test that awaits at the end of Act 4.

The Path to Malachai

Malachai is more than just another boss—he's a skill check, a gear check, and a durability test all wrapped in one horrifying package. As the final enemy in Act 4, he marks a transition from the early game into the core story of Path of Exile.

Before you reach him, you must face resurrected versions of three other major foes: Doedre, Shavronne, and Maligaro. They return with familiar but enhanced mechanics, and they must be defeated before Malachai reveals himself.

When you finally enter the Black Core—the arena where Malachai resides—you'll face a multi-phase encounter. Each phase becomes more intense, layering on mechanics like:

Slamming tentacle attacks that can one-shot the unprepared.

Persistent chaos damage ground effects that punish you for standing still.

Periods of invulnerability where Malachai regenerates unless you destroy his supporting hearts.

To defeat him, you'll need more than raw power. You'll need movement, timing, and resource management.

Preparing for the Battle

Before you take on Malachai, ensure your character is prepared:

Level: Aim for level 35 or higher to handle the incoming damage and deal enough yourself.

Resistances: Fire, Cold, and Lightning resistances should be at 75%. If they're low, upgrade your gear or use resistance flasks.

Chaos Resistance: Not mandatory, but helpful. You can mitigate chaos zones by staying mobile.

Flasks: Use a combination of instant life flasks, utility flasks (Granite, Basalt), and a Quicksilver Flask for movement.

Movement Skills: Equip Dash, Flame Dash, Leap Slam, or similar abilities to quickly reposition and dodge deadly attacks.

Positioning is everything in this fight. Keep your distance when possible, avoid staying in one place too long, and recognize the animation cues before Malachai uses a high-damage move.

The blood heart phases are key points in the fight. Malachai becomes immune and tries to regenerate. Destroying the hearts quickly shortens these dangerous periods and prevents him from recovering too much life.

Executing the Fight: Malachai's Phases

The battle unfolds in three phases:

Phase One: Malachai opens with basic patterns—blood tentacle slams, chaos projectiles, and teleporting strikes. He will summon hearts periodically. Kill them quickly and get ready for the next phase.

Phase Two: His patterns intensify, and damage zones become more common. He now uses multiple chaos pools at once, and his slam attack widens in area. Dodge constantly and take advantage of brief damage windows when he recovers from a heavy attack.

Final Phase: The arena becomes partially flooded with deadly ground effects. Malachai moves faster, slams more often, and attacks more aggressively. At this point, movement skills, flasks, and good timing become the only way to survive.

In all phases, resist the urge to stand still for extra damage. Staying alive and striking in short bursts is far more effective.

Role-Specific Strategies

Different builds handle Malachai differently. Here are some strategies by archetype:

Melee Tanks (Juggernauts, Slayers): Use your durability to survive close quarters but retreat during slams. Enduring Cry and Fortify help mitigate large hits.

Casters (Elementalist, Inquisitor): Stay at long range. Use Orb of Storms or Flame Wall to deal passive damage while dodging. Keep Flame Dash ready.

Summoners (Necromancer): Let your minions take aggro. Use Skeletons or Spectres as shields and attack with Desecrate and Offering spells as needed.

Bow Builds (Deadeye, Raider): Maintain mobility. Avoid chaos zones and keep your Mirage Archer active for consistent damage while you dodge.

Cyclone Builds (Slayer, Champion): Engage only in safe bursts. Cyclone provides some mobility, but don't commit to long spins—Malachai can punish that easily.

Victory and the Road Ahead

Once Malachai is defeated, you complete Act 4 and gain access to Oriath, the beginning of Act 5 and the midpoint of the story campaign. Your journey is far from over, but defeating Malachai confirms that your build is on the right path.

You'll also unlock the next level of the Labyrinth—Cruel Labyrinth—which offers two additional Ascendancy points and access to even more powerful passives. Now is a good time to:

Replace outdated gear.

Rework gem links for more synergy.

Upgrade flasks and jewelry.

Invest in movement and survival options for the next set of bosses.
