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. The debuff is also applied before your hero's attack lands, even if the attack missed.

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"
