Banshee

A Banshee was a female undead phantom, a selfish, strong-willed spirit that embodied the essence of hideousness. They delighted the death to any living creature.

Appearance
A banshee didn't have a defined shape rather a misty form with vague and flowing features that mirrored her former form in life. As time wore on a banshee became more and more distorted, though still was recognizable as a humanoid. In the same way a banshee retained a shadow of her former appearance, she was also able to speak and understand the same language with which she was fluent in life.

Although their shape was incorporeal the appearance of a banshee was horrific, and their mere presence would draw the energy from their surroundings to the point of stunting local floral growth.

Combat
Banshees hated all living things with an unholy fury; they could sense life approaching them and would attack anyone who trespassed in their territory. Along with their terrifying visage, the mere touch of a banshee would drain her victim.

The banshee's most feared weapon was a piercing wail that was as harmful as any material weapon. This scream was deadly to almost all who could hear.
