Path of Exile 2 (PoE 2) continues the legacy of its predecessor with an even deeper and more complex world full of dangerous bosses, intricate mechanics, and valuable loot. One of the most challenging and rewarding bosses players will encounter in Path of Exile 2 Trade is Olroth, Origin of the Fall, the central antagonist of the Expedition League. This powerful boss tests a player's understanding of mechanics, timing, and the ability to adapt on the fly.

In this guide, we’ll walk through everything you need to know to prepare for, encounter, and defeat Olroth, Origin of the Fall. From his lore and mechanics to strategies for tackling him with various builds, we’ll cover it all to ensure your success in the Expedition League.

Who is Olroth, Origin of the Fall?

Olroth is one of the primary bosses in PoE 2, introduced as part of the Expedition League. This massive and ancient being has ties to the deep and hidden history of Wraeclast, an immortal embodiment of decay, corruption, and the fall of empires. Olroth’s lore is intertwined with the destructive force that threatens all of Wraeclast, stemming from the collapse of ancient civilizations that wielded powerful, destructive magic—magic that now lies dormant but is dangerously influential.

As the Origin of the Fall, Olroth is not only a powerful enemy in combat but also a symbol of the impending doom that threatens to unravel the world. His influence is marked by the wreckage of entire societies, and his very presence makes the ground tremble as his destructive powers can reduce even the most fortified cities into ruins. It’s no surprise that such a figure would be a formidable adversary.

In terms of gameplay, Olroth is a multi-phase fight that requires players to adapt to changing combat conditions, deal with massive damage output, and counter devastating debuffs that can quickly overwhelm any unprepared player.

Encountering Olroth

The fight with Olroth takes place within the Expedition League’s campaign area, which is marked by the remnants of ancient civilizations and the corrupted earth. Players will stumble upon his lair through the Expedition questline, as they dig deeper into the league mechanics.

You’ll find Olroth after completing a series of challenges in the Expedition map. However, before encountering Olroth, you will have already faced many smaller Expedition bosses, providing a preview of the challenging encounters ahead. Olroth’s fight is different from most due to the layered mechanics and multiple phases that demand skillful execution and timing.

To unlock Olroth, you will need to complete the Expedition bosses leading up to him. These bosses include more straightforward challenges but become progressively more difficult. Once you have defeated these preliminary bosses, you can finally challenge Olroth in his lair, which is marked by shattered, crumbling structures and toxic, decayed landscapes that are a reflection of his corrupted nature.

Olroth’s Fight Mechanics

Olroth’s encounter in PoE 2 is multi-faceted, requiring players to manage several key mechanics simultaneously. The boss fight is divided into several phases, each of which introduces new challenges and abilities that require quick reflexes and adaptability. Here's a breakdown of what you can expect during the fight:

Phase 1: The Initial Assault

The first phase of the fight involves Olroth’s basic attacks, which consist of wide-area damage and high burst attacks. His movement is slow but deliberate, and he often telegraphs his attacks. This phase serves as a way for players to get familiar with his attack patterns and gain a feel for the fight.

During this phase, Olroth will cast the Corruption of Ages ability, which creates a series of decay zones on the battlefield. These decay zones are marked by dark, pulsating rings that spread across the area. Players who step into these zones will suffer heavy damage over time (DoT) and a debuff that reduces their overall damage output.

Phase 2: Summoning the Fallen

At around 50% health, Olroth will enter his second phase. During this phase, he will summon Fallen Champions—powerful creatures that embody the decay of the world. These creatures are powerful and have a variety of abilities that can cripple unprepared players. They can summon smaller adds, deal heavy burst damage, or create zones that enhance Olroth’s own attacks.

The Fallen Champions are not just there for decoration—they significantly increase the difficulty of the encounter. If left unchecked, they can quickly overwhelm the player, so it’s important to focus on eliminating them while managing Olroth’s primary attacks. Some strategies recommend focusing on the champions first, as their presence can make the later stages of the fight significantly harder.

In addition to the champions, Olroth will occasionally cast Shattering Scream, which sends out a wave of sound energy that can stagger players and break their movement. Players who are hit by this ability may find themselves stunned for a few seconds, leaving them vulnerable to Olroth’s following attacks.

Phase 3: The Descent Into Madness

Once Olroth reaches around 25% health, he will enter his final phase, where he fully unleashes his destructive potential. At this point, the arena will begin to collapse, and the environment will change, becoming more hostile. The decay zones will increase in size and frequency, and Olroth will start using his most devastating abilities.

One of the most dangerous abilities he uses in this phase is called Winds of Ruin. This ability creates a violent tornado-like effect that pulls players toward Olroth while dealing significant damage. The longer you remain inside the effect, the greater the damage, and it’s essential to quickly escape the pull and reposition yourself to avoid being consumed.

In addition, Olroth will cast Echo of Destruction, which creates an area of total chaos. In this area, all damage is amplified, and the entire battlefield becomes a death zone. Players will need to be extremely careful when navigating this area, as it can easily wipe out entire parties if they fail to dodge Olroth’s attacks or stay out of the chaotic area.

Finally, Olroth’s Final Fall will trigger when his health hits the 5% threshold. This is a desperation move where he becomes incredibly aggressive and deals massive damage with his core attacks. If the players have not yet defeated him, they must carefully dodge his last-ditch efforts while trying to land the final blow.

Strategy Tips for Defeating Olroth

1. Manage the Decay Zones

The Decay Zones in Phase 1 and Phase 2 can be incredibly dangerous, especially if multiple zones overlap. Be sure to keep an eye on the battlefield and move out of the decay zones quickly. Having a movement skill like Leap Slam or Flame Dash will help you avoid damage and reposition yourself quickly.

2. Prioritize Fallen Champions

The Fallen Champions in Phase 2 should be dealt with as soon as possible. These enemies have dangerous abilities and will quickly overwhelm you if not handled efficiently. While dealing with Olroth, try to take down these adds in priority order, focusing on the ones that deal the most damage.

3. Positioning is Key

Olroth’s Shattering Scream and Winds of Ruin can stagger you and deal massive damage. It’s crucial to keep moving during the encounter, as standing still for even a moment can lead to devastating consequences. Use positioning to your advantage and keep enough distance from Olroth to react to his abilities.

4. Focus on Dodging

In Phase 3, the battlefield will become chaotic with increased decay zones and the Echo of Destruction ability. If you get caught in these areas, your chances of survival drop significantly. Focus on dodging his attacks and positioning yourself in safer zones to deal damage. If your build has high evasion or movement speed, this can give you the upper hand in surviving Olroth’s final phases.

5. Time Your Damage

In the last phase, Olroth’s Final Fall causes him to deal a lot of damage in a very short amount of time. It’s critical to time your offensive abilities carefully, ensuring that you can output enough damage to defeat him while simultaneously avoiding his attacks. If you’re playing with a team, coordinate your damage output to maximize your chances of defeating him before he wipes the group.

Recommended Builds for Olroth

When facing Olroth, certain builds excel more than others due to the nature of the fight. Here are some recommended builds to help you tackle Olroth:

1. High DPS Builds

Olroth’s long phases and high health pool mean that you need a high damage-per-second (DPS) build to defeat him quickly. Bow and Spellcaster builds that focus on sustained damage output are ideal for this fight. Consider using Flame Totem or Flameblast to deal constant damage while avoiding close combat.

2. Tank Builds

Given the immense damage output from Olroth, tank builds with high life and energy shield can be incredibly effective. The goal here is to withstand damage from decay zones and the various abilities while keeping Olroth occupied. A Guardian or Juggernaut build with high mitigation and regeneration will serve you well during this boss fight.

3. Dodge and Mobility Builds

Since positioning and dodging are vital to surviving the encounter, mobility builds that enhance your evasion and movement speed will help you avoid Olroth’s deadliest abilities. Summoner or Assassin builds can use their high evasion and mobility to dodge Olroth’s attacks while dealing significant damage from a distance.

Conclusion
