Simulacrum stands as one of the most demanding and rewarding endgame challenges in Path of Exile 2, often regarded as a key to ultimate victory for players seeking to push their builds and skills to the limit. It is a wave-based encounter tied to the Delirium mechanic, featuring up to 15 increasingly difficult waves of monsters, culminating in battles against two unique bosses, Kosis and Omniphobia. Successfully navigating Simulacrum not only tests your character’s damage output and survivability but also grants access to some of the game’s best loot and progression rewards.
One of the main reasons Simulacrum is considered crucial to endgame success is the quality and quantity of rewards it offers. Each wave defeated yields piles of valuable loot, including unique items, high-tier currency, rare crafting materials, and Distilled Emotions, which are essential for enhancing Delirium encounters and item crafting. These rewards can significantly upgrade your gear and improve your build, enabling you to tackle even tougher content. The bosses at the end of the waves drop exclusive items and provide a substantial challenge that demands mastery of game mechanics.
However, Simulacrum is not for the faint of heart. The encounter scales in difficulty with each wave, increasing monster life, damage, and modifiers that add deadly effects such as elemental damage or monster abilities. Higher difficulties reduce the number of player respawns and increase the Delirious Effect, which boosts monster toughness and damage further. This scaling ensures that only well-optimized builds with strong area damage, evasion, and survivability can consistently clear the encounter. Players must be prepared with extensive knowledge of their character’s capabilities and a solid strategy to survive the relentless waves and boss fights.
The encounter also provides strategic depth. Players must balance aggressive clearing with resource management, often relying on consumables like Omens of Resurgence to restore life and energy shield during waves. Positioning and movement are critical, as the arenas vary in size and layout, sometimes restricting mobility and requiring adaptability. Prioritizing Kosis first during boss phases is a common tactic, as his icy attacks can severely limit battlefield control.
Simulacrum also integrates tightly with the broader Delirium mechanic and Atlas progression. Collecting 300 Simulacrum Splinters from Delirium encounters allows entry into the event, encouraging players to engage with Delirium content across the Atlas. Completing Simulacrum grants Atlas passive skill points that enhance Delirium effects, creating a rewarding loop of challenge and progression.
Despite its appeal, Simulacrum’s difficulty and time investment have drawn mixed opinions. Some players find it overly punishing without highly optimized builds, while others embrace it as the ultimate test of skill and preparation. For those struggling, boosting services exist to help bypass the grind and secure rewards.
Simulacrum is a cornerstone of Path of Exile 2’s endgame, offering unparalleled rewards and a rigorous test of player skill and build optimization. It is a gateway to ultimate victory for those willing to invest the time and effort, blending intense combat, strategic resource management, and deep integration with the game’s Delirium and Atlas systems. Whether you conquer it solo or seek assistance, mastering Simulacrum is a defining achievement on the path to endgame mastery.
