In Path of Exile 2, most bosses are simply obstacles- test your build, claim your loot, and Path of Exile 2 Currency move on. But Mektul, the Forgemaster, breaks that mold entirely. He's not overly lethal by himself, but the environment and mechanics around him make this a build-breaking, time-sensitive encounter.

Where to Find Mektul
Location: Molten Vault
Zone: Drowned City (Act Three)
Quest: Treasures of Utzaal

Find the Molten Vault at the outskirts of your map- hug the outer walls of the Drowned City until you uncover it. The vault radiates heat and is impossible to miss once discovered.

Why This Fight Is Unique
Mektul's core challenge lies in environmental pressure. From the moment the battle starts, lava begins creeping toward you, slowly consuming the arena. You must defeat him before you're pushed into a corner- or melted alive.

Mektul's Attacks and How to Avoid Them

Hammer Slam: Charges and slams a hammer down. Low damage, Dodge to the side.
Axe Slash: Sweeping slash with visual wind-up. It may come as a double hit, Dodge back or behind him.
Leap Slam: Jumps toward ranged players and slams down, dodges sideways.
Magma Slam: Long wind-up followed by a magma trail. Dodge perpendicular to the trail.
Magma Slash: Slashes and spills magma across the ground. Sidestep quickly.
Detonate: Roars, detonating nearby glowing stalagmites. Run far from the stalagmites immediately.
Magma Circle: Creates an AoE circle around him that explodes after a delay. Exit the circle quickly.
Magma Walk: Retreats into lava and slowly advances, emitting rolling magma waves. Stay mobile and avoid obstacles.
