Desolator

The Desolator is an Item purchasable at the Main Shop, under Artifacts.

Tips

 * The Corruption debuff works against buildings, making it a great pushing tool. Split-pushing heroes can benefit a lot from it, allowing them to take towers down much quicker.
 * The Corruption debuff lasts quite long, so sometimes it is better to get the debuff on multiple enemies, instead of focusing only one target in team fights.

Trivia

 * In the transition from DotA to Dota 2, Desolator's name was changed from the Stygian Desolator to simply Desolator because a weapon of the same name already exist in the game "Anarchy Online"
