Tizophrenia

Tizophrenia are creatures of darkness. They are amorphous and look like a dense cloud of black mist. When within close proximity, a faint crackling and ringing noise can be heard even though no noise is present. They live in the darkest caves and sewers, such as the Kalban Undercity, far away from any light as it can seriously damage them.

Tizophrenia hunt alone or in small packs and kill their prey by damaging their sanity and senses until they can't escape. The ambient noise they make gets stronger as you get closer and physical contact causes temporary deafness and an unstoppable ringing sound in your ears. Continued exposure can lead to permanent hearing loss or even brain damage. Logically, the name comes from a combination of Schizophrenia and Tinnitus as they are known to inflict both on survivors.
