The Simulacrum is one of the most intense and rewarding endgame encounters in Path of Exile 2, designed to push your character’s build and skills to their limits. It consists of 15 waves of increasingly difficult Delirium monsters, culminating in battles against two unique bosses: Kosis, the Revelation, and Omniphobia, Fear Manifest. Successfully conquering the Simulacrum requires preparation, adaptability, and a solid strategy.
How to Access the Simulacrum
To enter the Simulacrum, you need to collect 300 Simulacrum Splinters, which drop from Delirium encounters scattered across the Atlas of Worlds. These encounters appear wherever you see the Delirium icon, and you can also boost splinter drops by using Distilled Emotions to instill maps with Delirium. Once you have enough splinters, they combine into a Simulacrum item that you place into the Realmgate to open a portal to the encounter. The Simulacrum begins in a twisted version of the Clearfell Lumbermill, though the arena changes as you progress through the waves.
Encounter Structure and Challenges
The Simulacrum is a gauntlet of 15 waves filled with Delirium monsters empowered by modifiers familiar from Delirium Waystones. Early waves focus on crowd control and survival, while later waves ramp up the number and strength of enemies, including rare monsters with devastating modifiers. The arenas vary in size and layout, sometimes offering wide-open spaces and other times more constrained areas, requiring you to adapt your positioning and tactics.
The two unique bosses appear randomly during the waves, sometimes even simultaneously, making the fight especially challenging. When both bosses appear, it’s crucial to prioritize Kosis first because his icy attacks restrict your movement and control of the battlefield. Managing these bosses alongside the relentless waves demands strong area damage and high survivability.
Key Strategies for Success
High defenses and damage output are essential. Evasion rating is particularly valuable because it allows you to avoid attacks entirely, which is critical when overwhelmed by numerous foes. While armor and energy shield can help, they are often insufficient alone against the sheer volume of enemies. Area damage skills that quickly thin hordes are vital to prevent crowding.
Bringing one or two Omens of Resurgence is highly recommended. These items restore life and energy shield when activated, providing crucial sustain during tough waves. Remember to activate them manually in your inventory when needed.
Rewards and Progression
Defeating the Simulacrum yields substantial rewards, including exclusive unique items, piles of currency, and valuable Distilled Emotions used to enhance Delirium encounters. The challenge and loot make the Simulacrum a pinnacle of Path of Exile 2’s endgame content, motivating players to refine their builds and strategies.
Conquering the Simulacrum requires collecting 300 Simulacrum Splinters from Delirium encounters, preparing a build with strong area damage and evasion, and mastering resource management. The encounter’s 15 waves test your ability to handle escalating enemy difficulty and powerful bosses. Prioritize crowd control, focus Kosis during boss fights, and use Omens of Resurgence for sustain. Success rewards you with valuable loot and progression, making the Simulacrum a must-master challenge for serious Path of Exile 2 players.
