Anub'arak, Nerubian Assassin best anti-agi type hero

Anub'arak was once the greatest champion of the Nerubians, but fell in the Second War of the Spider. He was resurrected by the Lich King Ner'zhul, who promised him eternal undeath in exchange for his unswerving loyalty. His layers of spiked armor are nearly impregnable, causing severe damage to attackers. When threatened, he shoots these spikes through enemies maiming and disorienting them. He channels his dark powers into a bolt of disarming negative energy, and those who witness him blending into the shadows of the frozen tundra have never lived to tell the tale.
