Abilities[edit | edit source]

Target Unit
Targets an enemy, removing buffs from the target and slowing it for 4 seconds.
Cast Range: 600
Move Speed Slow: 100%
Non-Hero Root Duration: 3
Slow Duration: 4
Cooldown symbol.png 4
Blocked by Linken's Sphere. Still loses a charge when blocked.
Debuff Item Diffusal Blade Slow: Dispellable with any dispel.
Debuff Rooted: Dispellable with any dispel.


  • The dispel is applied first, followed by the slow.
  • The slow decreases in 0.8 second intervals, so it slows for 100%/80%/60%/40%/20%, going one step down every 0.8 seconds.
  • When cast on non-hero units, it roots the target for the initial 3 seconds, preventing it from moving and casting certain mobility spells.
    • The slow is still applied to the target, so that it still is slowed for the remaining duration once the root wears off.
    • Does not interrupt the target's channeling spells.
    • Does not provide True Sight over the target.

Not a Unique Attack Modifier. Partially usable by illusions. Does not pierce spell immunity.
Each attack burns 50 mana from the target, and deals 0.8 physical damage per burned mana. Burns 16 mana per attack from melee illusions and 8 mana per attack from ranged illusions. Does not stack with other manabreak abilities.
Mana Burned per Hit (Hero): 50
Mana Burned per Hit (Melee Illusion): 16
Mana Burned per Hit (Ranged Illusion): 8
Burned Mana as Damage: 80%
Partially usable by illusions. The amount of mana burned is reduced for illusions.
Not a Unique Attack Modifier. Does not stack with other Mana Break abilities.


  • The damage is directly added to the owner's attack damage.
  • Does not work against allied units when attacking them.
  • Applies the mana loss first, and then the damage.
  • Effectively increases a hero's attack damage by 40 against units which have enough mana to burn.

Recommended heroes[edit | edit source]

Phantom Lancer.png
Phantom Lancer
  • In conjunction with Juxtapose icon.png Juxtapose​, Spirit Lance icon.png Spirit Lance​ and Doppelganger icon.png Doppelganger​, 14 illusions plus Phantom Lancer icon.png Phantom Lancer​ himself will deal a total of 274 Mana Burn per attack, assuming all illusions are attacking one hero. 306 if Manta Style icon.png Manta Style illusions are included.
  • Purge complements his Spirit Lance icon.png Spirit Lance​, providing a total of 7.25 seconds slow and removing enemy buffs.
  • The Manabreak + 25/35 agility will equate to 65/75 additional physical damage per attack.
  • Purge can be used to slow heroes he attacked with Blink Strike icon.png Blink Strike​, which allows him to get more hits from behind while chasing his target.
  • While channeling Tricks of the Trade icon.png Tricks of the Trade​ every enemy hit will be affected by Manabreak. This can prevent multiple enemy heroes from casting mana-heavy spells because they don't have enough mana left.
  • Manabreak gives Illusions from Haunt icon.png Haunt​ an additional damage source. It also ensures every enemy hero hit by her Haunt-illusions has less mana available.
  • Purge allows Spectre to slow enemies she caught with Reality icon.png Reality​.
Naga Siren.png
Naga Siren
  • With Manabreak Naga Siren and all her Mirror Image icon.png Mirror Image​s drain a total of 98 mana per attack, assuming all illusions are attacking one hero. The added agility also increases the damage of her illusions.
  • Purge is also an effective slow for situations in which Ensnare icon.png Ensnare​ is not usable.

Effective against[edit | edit source]

Wraith King.png
Wraith King
  • Manabreak can be used to drain Wraith King's mana, which results in him being unable to use Reincarnation icon.png Reincarnation​ when he dies. Remember that Manabreak's effectiveness is tied to your own attack speed, when your hero has a slow attackspeed, you should consider using Necronomicon 1 icon.png Necronomicon to drain Wraith King's mana faster.
  • Manabreak can deal more effective Damage against Medusa since it depletes her manapool directly, so that Mana Shield icon.png Mana Shield​ blocks less damage.
Ghost Scepter icon.png
Ghost Scepter
  • If enemies are using Ghost Scepter to survive against you, Purge can be used to dispel Ghost Form, allowing you to once against attack them.

Trivia[edit | edit source]

  • The Manabreak passive used to be called Feedback and got changed at some point without notification.
