Witch

Description from original post (created 2014-03-03 17:53):

The Witch is one of the Special Infected and the only one to display an initially passive response to presence of Survivors.[1] She is also the only non-playable Special Infected.

When alert to the presence of an uninfected human or flashlight, she will look in the human's direction and make a low warning growl: this signals an incipient attack. If the human backs off, switches the light off or moves quickly out of her presence, she will fairly soon settle back into a passive state. But if the threat persists, she will launch an attack directed at the human who "startled" her at great speed, singling out the person who provoked the attack. She is able to incapacitate her victim instantly whereupon she frenziedly slashes that person with her clawed hands, only stopping if either she or the victim dies.
