Sculk

The Sculk is a soul/experience orb consuming parasite that roots deeply into both the landscape, and those who become infected by it. It has been shown to be sentient, but shows little more desire than that of feeding and spreading. At least one variant has displayed a higher level of intelligence to the point of a full sapient hierarchy. Its spread through an environment can be propogated by killing creatures in range of its growth. It has so far proven vulnerable to high heat, and seems unable to penetrate Blackstone blocks and constructions.

Transmission
The Sculk primarily spreads by making contact with the internal organs or bloodstream of a living creature. This method has been displayed in ways such as:
 * Being attacked with a weapon or object coated in the Sculk


 * Drinking or eating Sculk contaminated material

So far, the Sculk has proven ineffective at infecting inorganic beings such as Mattobots, as well as those with an incorporeal form.

Symptoms
Observed symptoms of Sculk infection include:
 * The need to consume souls, particularly fresh from a living creature (Seems to be Cato and Aldous specific)
 * Hypersensitivity to sound and bright lights
 * Blindness
 * The desire to spread the Sculk via contamination of others and consumption of experience orbs
 * The growth of black/blue/green Sculk patches on the hosts body
 * The eyes of the infected changing color to a bright cyan
 * Being able to hear the "voice" of the Sculk, and thus being susceptible to its influence
