This guide breaks down where to find him, what mechanics to expect, and the best strategies to bring him down.

Who Is Captain Hartlin?

Captain Hartlin is introduced during the Dark Mists questline in Act Four. Lore-wise, he's the long-lost son of Freya Hartlin, who tasks you with finding him in the fog-shrouded seas of Kedge Bay. Sadly, when you discover him in Journey's Edge, it's too late-Hartlin has been transformed into a grotesque undead, his body fused with nautical weaponry and cursed relics.

This fight is a turning point in Act Four, testing your ability to manage both single-target boss pressure and dangerous area mechanics.

Where to Find Captain Hartlin

Quest: Dark Mists
Location: Journey's Edge, Kedge Bay Island
Act: Four

As you progress through the fog-filled paths of Kedge Bay, you'll eventually reach Journey's Edge, a weathered battlefield where Hartlin awaits. The environment is open, giving him room to unleash his wide-area abilities, so positioning is vital.

Captain Hartlin's Strengths and Weaknesses

Armor: Heavy Armor - resists physical damage heavily
Resistance: Light Frost Resistance
Mobility: Slow-moving, deliberate
Weakness: Magic damage, stuns, and armor-piercing skills

The biggest hurdle in this fight is Hartlin's physical resistance. Melee-focused builds will struggle unless they use armor-piercing skills or invest in powerful gear upgrades. Spellcasters, however, will find the fight more forgiving since Hartlin's resistance to elemental magic is weaker.

Investing Path of Exile 2 Currency to upgrade your gems and gear-or even choosing to buy POE2 Items to fine-tune your build-can make a dramatic difference in this encounter.

Captain Hartlin's Wheel Mechanic

The most unique feature of this fight is the captain's wheel strapped around Hartlin's neck. At any given moment, the top skull of the wheel glows one of three colors-Purple, Green, or Blue-which determines his next special attack. Hartlin will periodically spin the wheel during the fight to change the active color.

Here's a breakdown of his color-coded abilities:

Purple (Summon Skeletons): Hartlin raises a dozen skeleton minions to harass you. While they aren't individually strong, their numbers can overwhelm, forcing you to balance crowd control with keeping pressure on the boss. AoE skills shine here.
Green (Anchor Drop): Hartlin calls down a massive anchor from above, creating a large area-of-effect strike. If you're caught in the center, the damage is devastating. The good news is that Hartlin pauses briefly to cast this, giving melee players a chance to land safe heavy hits once the anchor lands.
Blue (Spectral Orbs): Hartlin unleashes waves of spectral orbs that track loosely toward your position. Each deals moderate damage, and the danger lies in the numbers. Constant movement is required to weave between the orbs.

Additional Mechanics

Beyond his wheel-based specials, Captain Hartlin employs a mix of heavy-hitting nautical attacks:

Anchor Swing: A wide melee swing with his oversized anchor. Slow but punishing if mistimed.
Cannon Blast: A ranged shot from the small cannon mounted to his side. The projectile is quick but dodgeable if you stay alert.
At 33% health, Hartlin transitions into his ultimate phase:

"Fire in the Hole!" - Hartlin summons a circle of ghostly cannons around the arena, which bombard the field with explosive shots. The best counterplay is to move into the center of the circle and run in a tight loop. Doing so causes the cannonballs to overshoot and miss you entirely.

This final phase creates chaos but poe2 trade site also signals that the end is near. Surviving the cannon barrage lets you finish him off.
