The Zer'atai have always been known for their tradition of adorning armor with the bones of slain Zerg. However, such traditions would not serve this ill-fated templar well, as a lapse in judgment permanently fused the templar to his armor. Stripped of his name, his sanity and his origins, Shadow entered The Void itself, where he was greeted warmly by the Dark Voice.
The Dark Voice channels energy through Shadow, allowing him to blur the lines between reality and The Void.
Shadow does not appear on the minimap. While out of combat, Shadow becomes harder to see, and gains 3% movement speed every 5 seconds up to 21% movement speed (35 seconds). The stacks are removed when shadow takes or deals damage.
Shadow generates a vortex by compressing space into a point, sucking in nearby units over 2 seconds. When released, the vortex reduces enemy Movement Speeds by 33/44/55/66%, and increases allied Movement Speeds by the same amout for 2.5 seconds.
Shadow generates a 6/9/12 radius shroud of darkness at target location for 8 seconds. Enemies in the shroud have their sight radius reduced to 0. While in the shroud, gains +30% Weapon Speed, and +15% Movement Speed.
