Spectre


 * Difficulty: Medium
 * Skill Curve: Medium

Spectre is a global-based melee tank hard carry that is, in DotA 1, sometimes called "the most problematic balance nightmare of a hero in the game" because of her extremely strong skillset, which warrants constant big nerfs spanning years and yet is still a very solid hero. Her first skill is Spectral Dagger - it fires a dagger at a target or position and leaves behind a trail. Any unit that collides with the initial trail will take damage, be slowed, and will begin making a trail of their own which is left behind from where they walk. Spectre also gains movement speed and no collision while on the trail, meaning she can climb up cliffs or go through units. This can be very useful in clutch situations as Spectre can scale walls to escape or gank an unsuspecting enemy. Her second skill is a passive that gives a lot of bonus damage if she's attacking an enemy hero that doesn't have allies closeby, which emphasizes her picking unsuspecting heroes off and pairs well with her ultimate. Her third skill is a very powerful passive that reduces and reflects a portion of the damage she is taking in a large AOE, which is actually amazing damage when seen in action. Her Ultimate is a global long-cooldown spell that creates an aggressive illusion at every enemy hero alive for several seconds. Spectre can choose to teleport to an illusion at any time, killing them all but moving her instantaneously. It is also very powerful, and can be used for several things, including killing a low health fleeing hero, causing confusion and damage in a teamfight, and teleporting to a fight. The last one is especially important as it allows her to farm freely as long as she wants, since she can just teleport to enemies when she needs to. She often gets vanguard and then radiance so she can tank damage and deal incredible damage in an AOE in teamfights from her dagger, illusions, her third skill, and radiance's burning effect.
