Additional information[edit]


Targets an enemy, slowing it for 4 seconds.
Cast Range: 600
Move Speed Slow: 100%
Non-Hero Root Duration: 3
Slow Duration: 4
Item Diffusal Blade Slow: Dispellable with any dispel.
Rooted: Dispellable with any dispel.


  • 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.

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.
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%
The amount of mana burned is reduced for illusions.


  • The bonus damage is dealt in one instance together with the attack damage, and counts as attack damage as well.
    • It can be lifestealed off of, but it is not considered by crit or cleave.
    • It is also not affected by percentage-based attack damage bonuses or reductions, but can be reduced with flat reductions.
  • Effectively increases the owner's attack damage by 40 against units which have enough mana to burn.
    • Effectively increases the attack damage of an illusion by 12.8/6.4 (melee/ranged) against units which have enough mana to burn.
  • Applies the mana loss first, and then the damage.
  • Does not work against allied units when attacking them.

Recommended heroes[edit]

Naga Siren icon.png
Naga Siren
  • With Manabreak Naga Siren and all her Mirror Image icon.png Mirror Images 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.
  • Inhibit is also an effective slow for situations in which Ensnare icon.png Ensnare is not usable.
Phantom Lancer icon.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 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.
  • Inhibit complements his Spirit Lance icon.png Spirit Lance, providing a total of 7.25 seconds slow.
  • The Manabreak + 20 agility will equate to 60 additional physical damage per attack.
Riki icon.png
  • Inhibit can be used to slow heroes he attacked with Blink Strike icon.png Blink Strike, allowing him to get more hits from behind while chasing his target and keeping his target inside Smoke Screen icon.png Smoke Screen much longer.
  • 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.
Spectre icon.png
  • Manabreak gives Illusions from Haunt icon.png Haunt an additional damage source. It also ensures that each enemy hero hit by her Haunt illusions has less mana available.
  • Inhibit allows Spectre to slow enemies she catches with Reality icon.png Reality.


Effective against[edit]

Wraith King icon.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 (unless Wraith King buys a Black King Bar icon.png Black King Bar or chooses his manaless Reincarnation talent). Remember that Manabreak's effectiveness is tied to your own attack speed; if your hero has a slow attack speed, consider buying a Manta Style icon.png Manta Style or use Necronomicon 1 icon.png Necronomicon to drain Wraith King's mana faster.
Medusa icon.png
  • Manabreak can deal more effective Damage against Medusa since it depletes her mana pool directly, so that Mana Shield icon.png Mana Shield blocks less damage.


  • Combine it with a Mask of Madness icon.png Mask of Madness to get both of the most cost effective DPS items in the game, to burn mana much quicker with the attack speed and lifesteal from the mana burned. The active of the Diffusal Blade will slow your target to hit more.
  • It is a good item combined with Manta Style icon.png Manta Style because illusions carry over Manabreak, increasing damage output. Combine this with Moon Shard icon.png Moon Shard (works on illusions if not consumed) to burn mana much quicker and increase DPS even more.
  • The Diffusal movement slow allow to hit and run enemy melee heroes as ranged.
  • If you are lacking any cheap spells to disable an enemy's Linken's Sphere icon.png Linken's Sphere, you can use Diffusal Blade to pop it out and use your other skills and items to completely disable the enemy.
