In Path of Exile 2, one of the most exciting mechanics you'll encounter while exploring Wraeclast is the essence system. These glowing monoliths containing trapped monsters offer a reliable way to upgrade items and experiment with crafting, without the need for high-end crafting orbs right away. But there's more depth here than just breaking open the prison and fighting the monster inside. By using the right tool, you can corrupt essences and unlock far more powerful or unpredictable rewards.

If you're trying to get the most out of essences and maximize your loot or crafting options, this guide will walk you through how to corrupt them and the possible outcomes.
What Are Essences in Path of Exile 2
Essences are special crafting materials that drop when you defeat monsters trapped inside essence monoliths. These monsters are easy to spot in the world: they appear frozen in crystal-like prisons, surrounded by pulsing energy.
Breaking them free requires using the essence they are tied to, and once defeated, you gain an essence item. These essences can then be used to upgrade your gear by forcing specific modifiers. Unlike traditional currency items such as Chaos Orbs or Exalted Orbs, essences give you more deterministic results, perfect for early and mid-game crafting when you need gear improvements fast.
How to Corrupt Essences
If you want to push essences beyond their normal use, you'll need to corrupt them. To do so, you must acquire a special item called the Remnant of Corruption.
Where to get it: Remnants of Corruption can drop from monsters in the world, appear in chests, or be traded with other players. Since they're a tradeable item, many players spend POE 2 Currency on them to stockpile for essence farming.
How to use it: Before releasing the essence monster from its crystal, apply the Remnant of Corruption directly to the essence monolith. This act of corruption will alter the outcome of what drops once the creature is defeated.
This step is crucial, if you release the monster without corrupting first, you'll lose the chance to enhance the drop.
The Main Corruption Outcomes
Corrupting an essence can lead to four powerful results, each tied to unique "special essences." These are far more valuable than regular essences and are highly sought after for their crafting potential:
Essence of Delirium: Upgrades a Normal item to Magic, or a Magic item to Rare, while also applying a random passive modifier. This adds unpredictability but can roll powerful affixes.
Essence of Horror: Forces a Normal or Magic item to Rare and guarantees one strong property. Excellent if you're looking for guaranteed upgrades.
Essence of Hysteria: Upgrades a Normal item to Rare with an added Item Rarity modifier, increasing your chances of loot explosions during farming runs.
