How To Get These Two Important Jewels In POE 2? - Controlled Metamorphosis Diamond & Megalomaniac Diamond

Feb 04, 2025

In Path of Exile 2 Early Access, the power of your build is largely determined by the gear you use in it. Many players may place great emphasis on items with obvious effects such as weapons or skill gems, but the jewel slots in each build with a unique play style are also very important.

Given the importance of this slot, this guide will introduce you to the two best gems for different build styles, namely Controlled Metamorphosis Diamond and Megalomaniac Diamond. Here, you will see how to obtain them and their specific uses so that you can maximize their effectiveness in the game.

How To Get These Two Important Jewels In POE 2? - Controlled Metamorphosis Diamond & Megalomaniac Diamond

Controlled Metamorphosis Diamond

First, let’s introduce the overview of this gem. It is a Unique Jewel in POE 2 and can only be obtained by defeating one of the most powerful pinnacle bosses in the game. The main function of Controlled Metamorphosis Diamond is to give your endgame build a huge upgrade, especially those endgame builds that need to have the best distribution of passive skill tree points to achieve maximum damage.

A word of caution here, since you are taking on one of the toughest bosses in the game, spend some POE 2 Exalted Orbs to upgrade most of the offensive gear in your build or add an affix before the fight, which may make your entire quest more comfortable and easier to succeed.

Location

Controlled Metamorphosis Diamond is one of the loot drops from a pinnacle boss called Xesht, We That Are One in Difficulty 4 Breach event in POE 2. You can find Xesht, We That Are One by using the Realmgate in the Atlas, which requires you to farm 3000 Breach Splinters in Breach nodes to synthesize Breachstones.

This method only works if you challenge Xesht, We That Are One at Difficulty 1, and the important gems you need require you to complete this fight at Difficulty 4. Fortunately, unlocking this difficulty does not require you to provide more farming materials, just keep defeating the boss of the previous difficulty.

Each Xesht defeated at a difficulty will reward you with 2 Breach Atlas points. After you get them, the boss’ difficulty will increase, so you can unlock Difficulty 4 by defeating it four times at increasing difficulty. But it should be noted that if you are in a group to challenge this boss together, only the player with the Breachstone will get those equally important points, and other teammates will not.

Function

After talking about the specific method of obtaining Controlled Metamorphosis Diamond, let’s take a look at its function. When placed in a Jewel socket, it will form two rings around itself, and its radius has 8 different values, namely: Very Small, Small, Medium-Small, Medium, Medium-Large, Large, Very Large, and Massive.

There are a lot of nodes in these two rings, and you can allocate some passive skill points that have a large actual benefit to your build here, so that you will not be bound by the passive skill tree. Also, unlike Time-Lost Jewels, Controlled Metamorphosis Diamond does not allow skill points to be allocated to any node within the circle, but only nodes that fall within the two rings around it, and the radius of the circle is not the larger the better, but is determined by the passive skills you need or want that may be closer to the gem slot.

In addition, Controlled Metamorphosis Diamond has two debuff modifiers: on the one hand, it can reduce resistance to all elements by 20%-5%, and on the other hand, it reduces Chaos Resistance by 23%-3%. The lower these debuff values, the better the gem.

Here is a good way to crack this debuff, to light up Chaos Inoculation Keystone in the passive skill tree, which can make your character immune to all Chaos damage and ignore the debuffs brought by Controlled Metamorphosis Diamond.

Megalomaniac Diamond

Likewise, Megalomaniac Diamond is a gem that can have a significant impact on your endgame build, and can even make your character’s damage ability more devastating. However, the steps you take to obtain it are also very troublesome, requiring you to not only challenge very powerful bosses in POE 2 but also use Random Number Generator to your advantage. Again, be prepared to have enough POE 2 Currency to upgrade and enhance your build.

Location

You will find Megalomaniac Diamond in the loot of Kosis, Revelation in Delirium event under Difficulty 4, and you also need to open Realmgate in Atlas to open you and its arena. Here, you need to provide 300 Simulacrum Splinters farmed from Delirium-infused Waystones and Delirium nodes to synthesize a Simulacrum to open this portal.

Like Xesht, We That Are One, Kosis, Revelation’s difficulty is increased by completing each level of the previous level to gain Delirium Atlas points. After repeating this four times, you will enter Difficulty 4, where the boss will drop the gems you need.

It is worth noting that Kosis, Revelation can also be randomly generated in regular Delirium maps, but this variant will not drop Megalomaniac Diamond and other POE 2 Items that are exclusive to the pinnacle variant.

Function

In a build, Megalomaniac Diamond has 2-3 modifiers, all of which will assign you the inscribed Notables passive skill immediately after it is inserted into Jewel socket, rather than progressing through the passive skill tree. Although this is essentially the same as the effect of Anointing an Amulet, you can use 2-3 passive skills at the same time instead of one. However, it is important to note that there can only be one Megalomaniac Diamond in a build, and it cannot be stacked.

Given the uncertainty of the passive skill buffs provided by Megalomaniac Diamond, its value is also uncertain. In the best case, it has 3 Notables passive skills that can be used in meta builds, so its value may exceed hundreds of Divine Orbs; but if it only provides you with Notables passive skills that cannot supplement your build, its value may be less than a POE 2 Regal Orb.

Another thing to note is that Megalomaniac Diamond cannot be modified because it is already in a damaged state when it is generated, so you cannot use Vaal Orbs to affect it. So if you want a very useful Megalomaniac Diamond, you must either farm it or trade it with other players.

The above are the specific methods and effectiveness of the two gem options currently available in POE 2 for the full game style. I hope that your build can achieve the maximum exploration potential with the help of them and bring you an excellent gaming experience. I wish you a happy game!
