Spectre

Mercurial the Spectre is a melee agility hero that uses her abilities to confuse and hound the enemy, letting her allies take advantage of the confusion. Her mobility is outrageous thanks to her Spectral Dagger which allows her to pass through objects and terrain and her ultimate which allows her to displace herself near any opponent at global range. She also deals incredible damage against lone targets, and is able to take and reflect huge amounts as well. While she may be a carry, her abilities make for excellent ganking set-ups, especially when her target is alone. Later in the game where team clashes are frequent, her role is focused more as a tank.

Trivia

 * The name Mercurial most likely comes from the DeviantART account of Kenneth Tan, the person who made the 6.28-6.32 loadscreen.
 * Spectre's alternate/fun name "Qwerty-" was given to spectre for remembering a Legendary Dota player Zaven "Qwerty" Terminasov, who passed away December 5, 2010.
 * Spectre's voice responses are overlayed with the same track playing backwards, a reference to the Avatar of Vengeance's voice in Warcraft III, and the voice of Spectre in Dota 1.
