The Scourge of the Skies is one of the most grotesque and memorable encounters you'll face in Path of Exile 2. Found in Act Four, this mutated shrike terrorizes the skies above Ngamakanui and serves as a true test of your ability to manage movement, damage, and resource control in confined arenas.

Defeating this boss isn't just a matter of raw power, it's about staying calm under pressure, reading its attack patterns, and knowing when to reposition. This detailed guide will walk you through everything you need to know about finding, fighting, and defeating the Scourge of the Skies.
Where to Find Scourge of the Skies
You'll encounter the Scourge of the Skies on Shrike Island, the third island in the Ngamakanui archipelago. It's a single-zone area that culminates in this boss fight, so there's no need to navigate a complex dungeon layout or multiple paths, just progress through the island until you reach the arena.
Before starting the fight, ensure you've upgraded your gear and replenished your flasks. This encounter demands mobility and endurance, so bring at least one movement skill gem, a defensive aura, and a way to deal sustained damage over time. Players who have invested wisely in their POE 2 Currency, buying quality support gems, skill upgrades, or better weapon bases, will find this battle far more manageable.
Understanding the Boss
The Scourge of the Skies is a mutated bird-like horror, part shrike, part nightmare. Its flesh appears fused with corrupted tendrils, and it constantly screeches as it swoops and slams across the battlefield. Beyond the visual horror, it possesses several distinct attack phases that you'll need to adapt to if you want to survive.
Primary Attacks and Patterns
Corrosive Puddle Slam
The Scourge will periodically dive into the ground, creating large pools of acidic bile that linger for several seconds. These zones inflict heavy chaos and physical damage over time.
Tip: Move the boss gradually around the arena in a circular pattern. This ensures the puddles don't overlap and block your escape routes later in the fight.
Visceral Spew (Projectile Rain)
Occasionally, the Scourge flaps its massive wings and launches a rain of fleshy projectiles across the arena. These can be dodged by moving perpendicular to the attack, but getting caught in multiple projectiles can drain your health quickly.
A Topaz Flask or a piece of gear with projectile damage reduction can significantly mitigate this.
The Plagueling Spawn
Perhaps the most unsettling part of this encounter, the Scourge will disgorge a Plagueling, a parasitic creature that runs erratically across the battlefield, slashing and leaping at you. After a short while, it re-enters the Scourge's body to continue the cycle.
Here's the key: do not kill the Plagueling.
If you destroy it, the Scourge becomes enraged, triggering a devastating attack where it rains viscera across the arena. This phase can easily wipe unprepared players. Instead, deal enough damage to force it back inside, then refocus your attention on the main boss.
