DOTA 2 Venomancer
Venomancer is a hideous monstrosity who casts an assortment of toxins to bring down his enemies. He uses a fast Venomous Gale attack to project his poison at all enemies in a narrow path in front of him, slowing victims greatly and dealing damage over time. His attacks are coated with Poisonous Stingers that both slow and damage afflicted enemies. He can summon Plague Wards to do his bidding-deploying them either far out in front of him to scout, or in the heart of the bloody battle itself, to fight and weaken enemies. The wards can also be used to push and block off routes of attack or escape. His ultimate attack, Poison Nova, unleashes a potent toxin in a large ring around his body, infecting everyone it hits, dealing large damage, but over a long time. Though this toxin isn't lethal, every other poison he carries is. He is exceptional at weakening enemies, and slowing them down so that they don't stand a chance in team fights.
