The Controlled Metamorphosis Diamond is one of the most powerful Unique Jewels in Path of Exile 2, offering incredible flexibility in passive skill allocation. For the right build, this Jewel can be a game-changer, allowing players to allocate passive nodes without connecting them through the skill tree.
However, getting your hands on this Jewel is no easy task. It is an exclusive drop from Xesht, We That Are One, a pinnacle Breach boss that can only be fought at the highest difficulty level. Moreover, rolling an ideal version of this Jewel is a challenge due to its variable radius and resistance debuffs.
If you’re wondering how to farm the Controlled Metamorphosis Diamond or whether it’s better to buy one instead, this guide breaks down everything you need to know.

How to Get the Controlled Metamorphosis Diamond in PoE 2
Step 1: Defeat Xesht, We That Are One (Breach Pinnacle Boss at Difficulty 4)
The Controlled Metamorphosis Diamond is an exclusive drop from Xesht, We That Are One, the strongest Breach boss in PoE 2.
Where to Find Xesht, We That Are One
To challenge Xesht, you need to enter a Breachstone encounter at the Realmgate in the Atlas.
How to Obtain a Breachstone
There are two ways to get a Breachstone:
1️⃣ Farm 300 Breach Splinters by running Breach-infused maps and Breach nodes.
2️⃣ Buy a complete Breachstone from the trade market or currency exchange.
Once you have a Breachstone, activate it at the Realmgate to enter the fight.
Step 2: Unlock Difficulty 4 for Xesht, We That Are One
By default, Xesht starts at Difficulty 0, and you need to increase it to Difficulty 4 to unlock the pinnacle version, which is the only variant that drops the Controlled Metamorphosis Diamond.
How to Increase Xesht’s Difficulty
- Each time you defeat Xesht, you earn 2 Breach Atlas points.
- These points can be spent to increase Xesht’s difficulty by +1.
- After defeating Xesht four times, you’ll be able to increase the difficulty to +4, unlocking the highest-tier version of the fight.
💡 Important: Only the player who owns the Breachstone will receive Breach Atlas points. Party members will not gain progress.
How Controlled Metamorphosis Diamond Works in PoE 2
The Controlled Metamorphosis Diamond is a Unique Jewel that creates two circular rings in the passive skill tree when placed inside a Jewel socket.
How It Modifies Passive Skill Allocation
🔵 Creates two rings around the Jewel socket in the skill tree.
🔵 Passive points inside these rings can be allocated without connecting them to the main path.
🔵 Ring size varies, meaning some Jewels are much better than others.
Radius Variations
There are eight possible radii for a Controlled Metamorphosis Diamond:
1️⃣ Very Small
2️⃣ Small
3️⃣ Medium-Small
4️⃣ Medium
5️⃣ Medium-Large
6️⃣ Large
7️⃣ Very Large
8️⃣ Massive
💡 Larger radii are generally more valuable because they offer more flexibility in passive allocation.
However, a smaller radius isn’t necessarily bad, as the ideal radius depends on your build and the location of your Jewel socket in the passive tree.
Debuffing Modifiers on the Controlled Metamorphosis Diamond
Unlike some other Jewels, the Controlled Metamorphosis Diamond comes with two built-in debuffs:
❌ (-20)-(-5)% to All Elemental Resistances
❌ (-23)-(-3)% to Chaos Resistance
💡 The lower these values, the better the Jewel.
A perfect roll would have:
✔ -5% to All Elemental Resistances
✔ -3% to Chaos Resistance
For builds using the Chaos Inoculation Keystone, the Chaos Resistance penalty doesn’t matter, making the Controlled Metamorphosis Diamond an ideal pick.
Should You Farm or Buy the Controlled Metamorphosis Diamond?
Since Xesht at Difficulty 4 is a brutal fight, and getting a good roll is pure RNG, many players prefer to buy the Controlled Metamorphosis Diamond instead of farming for one.
