Path of Exile 2: How to Get the Megalomaniac Diamond

February 03, 2025

    The Megalomaniac Diamond is one of the most sought-after unique Jewels in Path of Exile 2, capable of providing game-changing passive skill allocations for high-end builds. With the right modifiers, this Jewel can push an already powerful character into an unstoppable force, making it one of the most valuable items in the game.

    However, getting a Megalomaniac Diamond is no easy feat. Players will need to defeat one of the toughest bosses in PoE 2, overcome multiple layers of RNG, and grind through Delirium content at the highest level.

    If you’re looking to farm the Megalomaniac Diamond or just understand why it’s such a high-value item, this guide covers everything you need to know.


    How to Get the Megalomaniac Diamond in PoE 2

     

    PoE 2 how to get Megalomaniac Diamond

     

    Step 1: Fight Kosis, the Revelation (Delirium Pinnacle Boss at Difficulty 4)

    The Megalomaniac Diamond is an exclusive drop from Kosis, the Revelation, the most powerful Delirium boss in Path of Exile 2.

    Where to Find Kosis, the Revelation

    To fight Kosis, you need to enter The Simulacrum, an endgame Delirium event that can be accessed at the Realmgate in the Atlas.

    How to Obtain a Simulacrum

    There are two ways to get a Simulacrum:
    1️⃣ Farm 300 Simulacrum Splinters by running Delirium-infused maps and Waystones.
    2️⃣ Buy a completed Simulacrum from the trade market or currency exchange.

    Once you have a Simulacrum, use it at the Realmgate to start the event.

    Step 2: Increase Simulacrum Difficulty to +4

    By default, The Simulacrum starts at Difficulty 0. To access Kosis, the Revelation, you need to increase the difficulty to +4.

    How to Increase The Simulacrum Difficulty
    • Each time you defeat the final boss of The Simulacrum, you earn 2 Delirium Atlas points.
    • These points can be spent to increase the Simulacrum’s difficulty by +1.
    • After completing the Simulacrum four times, you’ll be able to set the difficulty to +4, unlocking Kosis, the Revelation.

    💡 Important: The regular version of Kosis (which can spawn randomly in Delirium maps) does NOT drop the Megalomaniac Diamond—only the pinnacle version at difficulty 4 can drop it.


    How Megalomaniac Diamond Works in PoE 2

    The Megalomaniac Diamond is a unique Jewel that automatically allocates 2-3 Notables from the passive skill tree when socketed.

    What Makes It So Powerful?

    Bypasses pathing requirements – No need to waste passive points moving toward a Notable.
    Works like an Anointed Amulet – But grants 2-3 passive Notables instead of one.
    Can be worth hundreds of Divine Orbs – If it rolls valuable Notables for meta builds.

    💡 Limitations:

    • You can only equip ONE Megalomaniac Diamond at a time.
    • Always corrupted on drop (cannot be modified or influenced with Orbs).
    • RNG-based modifiers make finding a useful one extremely difficult.

    Since the Notables are randomly chosen, getting a perfect Megalomaniac for your build is incredibly rare. This is why most players buy one from the trade market instead of farming for the perfect drop.


    What Are Notables in Path of Exile 2?

    In the passive skill tree, there are three types of passive nodes:

    🟤 Small Nodes: Provide minor bonuses (e.g., +5% Attack Speed).
    🟠 Notables: Larger nodes that offer major build-defining bonuses.
    🔶 Keystones: Powerful nodes that completely change a character’s mechanics (e.g., Acrobatics, Chaos Innoculation).

    A Megalomaniac Diamond grants 2-3 Notables, making it an incredible tool for character optimization.

    Why Is the RNG So Extreme?

    • There are hundreds of Notables in the passive skill tree.
    • Getting three good ones that perfectly fit your build is almost impossible.
    • The best rolls are worth massive amounts of currency due to their rarity.

    💡 Example:

    • A Megalomaniac with three popular Notables for a Meta build can be worth 200+ Divine Orbs.
    • A Megalomaniac with useless Notables might sell for less than a Regal Orb.

    This huge variance in value is what makes the Megalomaniac Diamond one of the riskiest, yet most rewarding, unique Jewels in PoE 2.


    Should You Farm or Buy the Megalomaniac Diamond?

    Since farming Kosis, the Revelation at difficulty 4 takes time and resources, many players choose to buy a Megalomaniac Diamond instead.

    Final Thoughts

    The Megalomaniac Diamond is one of the most powerful and unpredictable items in Path of Exile 2. While getting one is challenging, the rewards are immense, as the right modifiers can completely transform a build.

    To summarize:
    Fight Kosis, the Revelation at Difficulty 4 in The Simulacrum.
    Increase Simulacrum difficulty by earning Delirium Atlas points.
    Megalomaniac Diamonds allocate 2-3 random Notables in the passive tree.
    Trading is the best way to get a useful roll since finding a perfect one is incredibly rare.

    If you’re serious about min-maxing your build, buying a Megalomaniac Diamond might be the best investment you can make!
