Venomancer

Venomancer is an Agility caster hero, who is focused on dealing damage over time. He is not granted with a big amount of base attack and its gain but can bring enormous area damage with his poisonous spells. If Venomancer could not kill his victim in face-to-face combat, be sure that they still will die of poison damage. He also has a good chasing capability, as his skills can greatly slow the movement speed of enemy heroes. Venomancer considered as a semi-carry because of his skill Poison Sting, that grants him passive slowing effect on his base attack.

Tips

 * Venomous Gale is one of the best level 1 skill in the game. Try to use it to get the first blood with a good partner.
 * Don't be afraid to spam your Plague Wards. They may not be that great on their own, but they are incredible if you have a lot of them.
