The breath of cockatrice is said to be able to kill any creature in Newerth. Although not able to outright kill, the toxic vapors exhaled by the cockatrice can severely disable and blind those afflicted.

Notes: By blind I mean the same effect as dark lady, you lose sight of your allies shared vision and are limited to things right around you. This skill would either be used as a way of taking a enemy hero out of fight, or picking off a hero for a kill, while you alone or with team mates attack the slowed and blind target. I envision the player using this hero would first use stoney gaze, then close the distance and use deblitiating breath. Then when the enemy uses a spell or item to try to help or escape, the player can use nulify to prevent it.
Visual: I’m thinking a purple mist or cloud, quickly exhaled and quickly dissipating. The unit afflicted should have purple overlay on there screen, and should tinted so others know he is debuffed.
