Path of Exile 2 Act 4 Boss Overview

Overpower the Blind Beast on Isle of Kin

This hulking brute in the Isle of Kin unleashes physical and lightning havoc right from the start. Stay mobile to avoid its sweeping melee strikes when close and leaps when you pull back.

At 75% health, brace for the raging combo: a roar precedes four rapid slams that fracture the ground into Voltaxic Sulphite pools. These linger, inflicting physical and lightning damage over time (DoT), so weave through the arena edges while chipping away.

Tame Krutog, Lord of Kin in Volcanic Warrens

Krutog mirrors the Blind Beast's physical and lightning profile in Volcanic Warrens, pounding with club overheads and hurling severed limbs from afar.

Dropping to 80% health, he devours Voltaxic Sulphite, upgrading his march with eruptions and adding vomit pools plus cone sneezes of the corrosive stuff. Prioritize lightning resistance and flask timing to endure the DoT fields.

Outmaneuver Captain Hartlin at Journey's End

Captain Hartlin's shipwrecked fury blends physical, cold, and fire in Journey's End. Melee brings cannon/anchor slams; ranged triggers slow waves.

Spectral anchors demand dodges on marked circles, and barrages fire sequentially from a player-ringed cannon circle. At 80%, green-glowing wheel spins unleash tracking spirit mortars. Kite skeletons and prioritize mobility.

Survive Scourge of the Skies on Shrike Island

This avian terror on Shrike Island sticks to physical damage. Back sweeps from behind lob blood projectiles; head slams (dodge cue) spawn lingering blood pools for DoT.

Blood barrages rain down, beak spikes spiral and erupt (bleed/maim debuff), and at 75%, it summons a fast-attacking Plagueling add and mortars blood—dodge-roll relentlessly.

Bury the Great White One on Whakapanu Island

Whakapanu Island's shark lord delivers pure physical punishment via lunging bites and combos.

At 85%, tornado dives summon dust circles, birthing three wandering tornadoes hurling piranhas. Hug arena walls to minimize pool coverage.

Silence Diamora, Song of Death in Singing Caverns

The donut-shaped Singing Caverns arena suits Diamora's physical/cold arsenal.

Intermissions at 65%/35%: she spins centrally, gazing petrifies (5 stacks = 4s stun); reflections on outer walls stack too; clear adds quickly.

Break Free from the Prisoner in Solitary Confinement

Solitary Confinement's two-phase Prisoner mixes physical/cold.

Immediately interact with the nearby ballista to stagger and halt regen—missing this prolongs the fight significantly.

Disrupt Torvian, Hand of the Saviour in Arastas

Arastas' Torvian wields physical/fire (freeze build-up, no cold damage).

Three scaffold mages channel buffs. Bait Torvian's rock toss to bases to interrupt the mages.

At all buffs/25%: axe bomb (dodge)—double axe holy eruptions. 25%: counterclockwise holy beam (fire DoT). Prioritize interrupting all three mages.

Shatter Benedictus, First Herald of Utopia in the Excavation

Benedictus in the Excavation pairs physical/lightning.

75%: channeled eruptions form/destroy circles—center then out. 65%: double boulder slams (dodge), lightning-infused boulders slamming/exploding. 60%: pillars shrink arena; eruptions become 5 walls to weave.

Unmask Yama the White in Halls of the Dead

Halls of the Dead host Yama's physical/chaos via staff swipes, Soulrend cone projectiles (chaos DoT debuff), exploding caustic sigils.

75%: clones on pillars (find real via proximity slam). 65%: time-freeze sends exploding clones—reach the circled one. Defeat drops Silver Coin for Trail of the Ancestors (2 passive points).

Triumph Over Tavakai the Chieftain in Heart of the Tribe

Heart of the Tribe's three-phase Tavakai escalates physical/cold/fire/lightning. Totems invoke Karui gods randomly (positioning matters).

Phase 1 & 2 Key Dodges:

Karui God Powers (Proximity-Based Effects):

Stack resists across elements and position yourself away from unwanted god totems (especially Kitava and Tawhoa).

FAQs on Path of Exile 2 Act 4 Bosses

What damage types does the Blind Beast deal?

The Blind Beast primarily inflicts Physical and Lightning damage through sweeps, leaps, and slams. At 75% health, its raging combo unleashes four slams that spawn lingering Voltaxic Sulphite pools, dealing physical and lightning damage over time (DoT). Stack lightning resistance above 75% and physical mitigation; always circle-strafe the pools' edges to minimize exposure.

How do you interrupt Torvian's mage buffs?

Position yourself near the wooden scaffolds holding the three mages above the arena. Bait Torvian's rock toss by standing at the scaffold base—the boulder will interrupt their channels. Watch icons under his health bar: crossed swords for combo slashes, shield for leap, holy symbol for axe toss. Prioritize interrupting all three to prevent deadly upgrades like tracking axes or crit-vulnerable holy walls.

What's the Silver Coin from Yama for?

Defeating Yama the White drops a Silver Coin. Exchange it at the Trail of the Ancestors for 2 passive skill points, a huge early boost. Time your run to this optional boss after clearing nearby zones for smoother progression.

Which Tavakai phase has god totem powers?

Karui god powers trigger throughout all three phases based on proximity to totems—position wisely to avoid debuffs like Kitava's Thirst (heals Tavakai on hit) or Tawhoa's vines (damage reduction). Phase 3 escalates danger, as every dodge-required attack randomly invokes a god power alongside fiery spikes and sunders. Flask for elemental ailments and maintain distance from unwanted totems.

How to handle Diamora's intermission?

At 65% and 35% health, Diamora triggers a minion intermission: she spins centrally in the donut arena, her gaze applying petrification stacks (5 stacks = 4s stun). Avoid her gaze and outer wall reflections (also stack petrify). Clear spawning minions quickly; at 35%, dodge rotating drowning bubbles. Hug the safe gaze-free section and prioritize adds.

Does the Prisoner regenerate health?

Yes, the Prisoner regenerates at 50% (transition to Phase 2) and 20% (gains blood tendrils). Immediately interact with the nearby ballista to stagger and halt regen—missing this prolongs the fight significantly. Phase 2 adds expanding frost circles; outrun them while dodging tendrils.

What debuff do Scourge of the Skies' beak spikes apply?

Beak spikes erupt in a spiral pattern, inflicting bleed and a 30% movement speed slow maim debuff on hit. Position to avoid eruptions entirely; at 75%, it also spawns a fast Plagueling add—reduce it to 50% HP to force retreat, preventing extra pressure.

Captain Hartlin's spectral anchor—how to dodge?

When Hartlin raises his anchor, a circle marks your location—immediately run out before the spectral anchor slams down for massive damage. Combine with clockwise circling during cannon barrages and quick skeleton clears from summons; at 80%, dodge tracking spirit mortars.
