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

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.
    • Effectively increases the attack damage of an illusion by 12.8/6.4 (melee/ranged) against units which have enough mana to burn.


This item is particularly useful on heroes that can create illusions.




  • The Diffusal`s active apply the most powerful slow of the game but has a limited amount of use that can only be refreshed after upgrading it. It is better to consume all the charges before upgrading it.
    • In light of this, if you expect your Level 1 Diffusal to run out of charges in the middle of a fight, lock the Diffusal and buy the recipe beforehand. Unlock it in the middle of a fight once you run out of charges.
  • Combine it with a 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 a Manta Style because illusions carry over Manabreak, increasing damage output. Combine this with 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.

  • Purge can be used to slow heroes he attacked with Blink Strike, allowing him to get more hits from behind while chasing his target and keeping his target inside Smoke Screen much longer.
  • While channeling 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 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.
Naga Siren
  • With Manabreak Naga Siren and all her 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.
  • Purge is also an effective slow for situations in which Ensnare is not usable.

Effective against

Wraith King
  • Manabreak can deal more effective Damage against Medusa since it depletes her mana pool directly, so that Mana Shield blocks less damage.
Ghost Scepter
  • If enemies are using Ghost Scepter to survive against you, Purge can be used to dispel Ghost Form, allowing you to once again attack them.


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