Essence is a form of energy that gives beings life. It can be harvested from dead and living beings by Necromancers whether those beings be mortal, angel, or demon. It is gained by summoning the fading life force of corpses, by rending a soul, or siphoning it directly from blood. It can even come from the Necromancer's own health. By doing so, every Necromancer ensures that they are seldom helpless of powerless. Necromancers use Essence to animate the dead, curse enemies, and command minions.
As a static resource, necromancers only have as much Essence as they harvest from their enemies. It does not fill up slowly over time, nor does it decay. Due to this peculiarity, Necromancers who are careless may find themselves out of Essence when they need it most. Necromancers who make the most of their power embrace the balance between exhausting Essence reserves and obtaining more from enemies, forever looking to the next battle. A necromancer with a full Essence pool is a terrifying adversary indeed, but they must carefully use their spells to keep enemies at bay.
Essence is capped at 200, and does not regenerate passively (but also does not decrease over time), only being replenished by primary skills such as Blood Siphon, or by other skills like Devour in battle. Overwhelming Essence passive increases the maximum cap by 40, and Paragon levels further add up to 50.
