Decompose is one of the Necromancer’s Basic Skills that provides them with corpses as well as the ability to gain extra essence.

With the Flesh Rending Aspect, Necromancers can get even more essence whenever Decompose creates a corpse, providing them with the ability to cast more skills.

This becomes extremely useful when you focus on using Decompose to generate Essence for your other skills based on what build you are using.

Flesh Rending Aspect Effects (Decompose Aspect)

With the Flesh Rending Aspect imprinted on one of your equipped items, you gain a certain amount of Essence whenever an enemy has been killed.

This will allow you to generate more Essence for the skills that you need to cast aside from the corpses that you can make use of.

By being able to gain more Essence over time, you can quickly unleash your other skills regardless of high Essence costs.

Flesh Rending Aspect Location

The Flesh-Rending Aspect becomes unlocked once you have completed the Nostrava Deepwood Dungeon, which can be found in the Pallid Glave north of Nostrava. (Fractured Peaks)
