Lesale Deathbringer the Venomancer is a hero from Dota Allstars and Dota 2. In Dota Allstars, he is a Agility Scourge hero, while in Dota 2, he is a Agility Dire hero.
Abilities
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.
Story
DOTA Allstars:
For those obsessed with death, poison is a necessary study. However, Lesale went a step too far. He experimented upon himself with various toxins and chemicals so that he could learn the secrets of death. These twisted his mind and mutated his body into a hideous creature, which embodies an immense hatred for all things pure. He can strike an enemy with a concentrated shots of poison or even spread a toxic gas throughout the floor, severely weakening and human alike.
