How to counter Spectre in Dota 2

Spectre flings a dagger to draw a Shadow Path, dealing damage and slowing the movement speed of any enemies along the trail. Units hit by the dagger also trail a Shadow Path. While treading the path, Spectre moves faster and phases through otherwise impassable terrain.

Sends an uncontrollable illusion at a target that follows and attacks the target. The Reality sub-ability may be used to teleport to the illusion, destroying it.

Spectre disperses part of the damage dealt to her, reflecting it to all nearby enemies. The effect lessens with distance.

Spectre assumes the target Shadow Step or Haunt illusion, destroying it.

Spectre and her illusions deal bonus Pure damage if attacking an enemy that does not have any allied units within a 350 radius around them.

Creates a spectral nemesis to haunt all enemy Heroes. Haunt illusions are uncontrollable, take extra damage, and deal less damage than Spectre herself. They ignore terrain. The Reality sub-ability may be used to teleport to the illusion, destroying it.
