Path of Exile 2 (POE 2) is known for its vast, complex mechanics and the incredible range of customization it offers players. Whether you are grinding your way through regular maps, battling powerful bosses, or fine-tuning your build for maximum efficiency, POE 2 constantly challenges players to think critically about how to develop their characters and optimize their gameplay. One of the most influential aspects of POE 2 builds is the equipment you use, particularly the unique jewelry items.

Among the many types of valuable items in POE 2, jewelry stands out because it offers significant advantages that can greatly enhance your character’s performance, even if it doesn’t always receive the same visual attention as weapons or armor. Of these, two particularly rare and powerful jewels—the Megalomaniac Diamond and the From Nothing Diamond—have become staples for endgame builds, providing massive potential for those who can acquire them.

This article will explore these two unique diamonds in detail, explaining their acquisition methods, what they do, and how they can change the way you play Path of Exile 2.

The Megalomaniac Diamond: Power Through Notable Passives

What Is the Megalomaniac Diamond?

The Megalomaniac Diamond is a unique jewelry item in Path of Exile 2 that has the potential to reshape your character’s passive skill tree. When equipped, this diamond provides 2-3 Notable passives on your tree, which can be a game-changer depending on your build. These passives are drawn from the expansive pool of Notables, each of which offers specific bonuses to either your defense, offense, or utility. If you roll well on the Megalomaniac Diamond, it can significantly enhance your build, making you a far more destructive force in combat.

However, the path to acquiring this jewel is not an easy one. The Megalomaniac Diamond is one of the most coveted items for endgame players, and obtaining it requires significant effort and some luck.

How to Acquire the Megalomaniac Diamond

To get the Megalomaniac Diamond, you must first face one of the game’s most formidable bosses: Kosis, the Revelation. This is a pinnacle boss that only drops the Megalomaniac Diamond under certain conditions.

The only way to engage with Kosis, the Revelation, is through the Simulacrum, a special feature in POE 2 that allows players to fight progressively harder versions of bosses from the game. To access Kosis, you need to farm Delirium nodes and ways tones that are infused with Delirium. The goal is to collect 300 Simulacrum Splinters, which can then be combined into one Simulacrum.

Once you have the Simulacrum, you will need to increase the difficulty of your encounter with Kosis by earning Delirium Atlas Points. These points are obtained by completing Simulacrum encounters on normal difficulty, and each win grants you 2 Delirium Atlas Points. The key here is to increase the difficulty of your Simulacrum encounter until you reach a +4 difficulty level, which unlocks the chance to fight Kosis, the Revelation.

Upon defeating Kosis at the required difficulty, you will have a chance to receive the Megalomaniac Diamond. However, it is important to note that Kosis spawns randomly in regular Delirium maps, but in those encounters, there is no chance of acquiring the Megalomaniac Diamond or any other unique item.

The Utility of the Megalomaniac Diamond

The Megalomaniac Diamond allows you to insert Notable passives into your passive skill tree. The jewel itself can only have 2-3 modifiers that offer Notables, and you can only equip one Megalomaniac Diamond at a time.

The value of the Megalomaniac Diamond is dependent on the Notables it rolls. If you receive Notables that synergize well with your build, it can significantly enhance your character’s performance. However, if the Notables are not compatible with your build, the value of the Megalomaniac Diamond may drop, making it less useful compared to other more common items.

For example, a Megalomaniac Diamond that grants access to key Notables for a meta build—such as Trickster or Pain Attunement—can dramatically improve the effectiveness of your build. On the other hand, a Megalomaniac Diamond with Notables that do not synergize with your chosen playstyle may not provide much benefit and could even be worth less than a regular Regal Orb in terms of overall utility.

The From Nothing Diamond: Unlocking New Passive Nodes

What Is the From Nothing Diamond?

Much like the Megalomaniac Diamond, the From Nothing Diamond is a rare and powerful item in Path of Exile 2. While the Megalomaniac Diamond focuses on adding Notables to your passive tree, the From Nothing Diamond works in a slightly different manner. When equipped, the From Nothing Diamond allows you to assign passive skill tree points to nodes that are outside of your usual accessible radius.

This functionality is useful for players who want to diversify their builds and gain access to passive nodes that would otherwise be hard to reach, especially those on the far side of the passive tree. However, the From Nothing Diamond’s radius is small, so it’s best used in conjunction with other forms of tree manipulation to maximize its potential.

How to Acquire the From Nothing Diamond

The From Nothing Diamond is even more difficult to obtain than the Megalomaniac Diamond. This jewel is dropped by King in the Mists, the pinnacle boss in the Ritual Atlas. To face this boss, you need to upgrade your Ritual Atlas tree until you reach the +4 Crux of Nothingness difficulty level. This will require you to defeat the boss multiple times on lower difficulty settings before you can finally challenge the King at the required difficulty.

Once you’ve unlocked the necessary difficulty level, you can enter the An Audience With the King event at the Realm Gate in the Atlas. Here, you will face King in the Mists, and after successfully defeating the boss, you will have a chance to receive the From Nothing Diamond. However, the drop rate is not guaranteed, so you may need to grind this encounter multiple times before acquiring the jewel.

The Utility of the From Nothing Diamond

When inserted into your jewelry slot, the From Nothing Diamond creates a small radius around a pre-selected keystone in your passive skill tree. Within this radius, you can allocate passive points to any node, regardless of its position on the tree. This allows you to bypass the usual limitations of your skill tree’s structure and access powerful nodes on the opposite side of the tree, or nodes that would typically be out of reach.

However, there is a trade-off: since the radius is small, you will need to plan your tree carefully to maximize the effectiveness of this item. To balance this, each From Nothing Diamond comes with a pre-selected keystone, which immediately establishes a new center of influence for the radius upon insertion. The jewel's utility lies in its ability to offer flexibility, but it must be used wisely within your build to truly shine.

Conclusion: The Value of These Rare Jewels

The Megalomaniac Diamond and From Nothing Diamond are incredibly powerful and highly coveted items in Path of Exile 2. Each offers unique advantages that can significantly improve your character’s performance by granting access to powerful Notables or allowing you to redistribute passive skill points in unconventional ways.

Both items are challenging to acquire, requiring players to face powerful pinnacle bosses under specific conditions. However, their rarity and difficulty of acquisition make them extremely valuable for endgame players who want to optimize their builds and achieve maximum power.

If you’re not interested in grinding for these jewels yourself, you can also look to trade with other players via POE 2’s official trading platform. Additionally, participating in Path of Exile 2 Currency giveaway events hosted by sites like MMOEXP’s Discord server can help you accumulate the necessary POE 2 Orbs to purchase these jewels and make your endgame experience even more enjoyable.

In the competitive world of Path of Exile 2, the ability to harness the power of these unique diamonds can make all the difference, taking your build from average to extraordinary. Whether you choose to farm them or trade for them, the Megalomaniac Diamond and From Nothing Diamond are indispensable tools for any serious player.
