The Diffusal Blade is an upgradable item purchasable at the Main Shop, under Artifacts. It can be upgraded by purchasing the recipe again.

Additional information[edit]

  • The item does not disappear upon using up all charges.
  • Upgrading the item improves its stats and refreshes the charge counter back to 8. Can be upgraded only once.
    • This means the charges cannot be refreshed a second time. A new Diffusal Blade has to be bought in order to get new charges.
  • The total gold cost for each level is 3150/3850.
  • One Diffusal Blade grants 2.86/4.29 armor, 20/30 attack speed, 110/165 mana, 0.4/0.6 mana regeneration and 0.71%/1.07% spell damage (and 20/30 attack damage to Agility attribute symbol.png agility heroes, or 10/15 attack damage to Intelligence attribute symbol.png intelligence heroes) on each level.

Abilities[edit]

Purge
Ability
Target Unit
Affects
Enemies
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

Modifiers
Debuff Item Diffusal Blade Slow: Dispellable with any dispel.
Debuff Rooted: Dispellable with any dispel.

Notes:

  • 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.


Manabreak
Partially usable by illusions. Does not pierce spell immunity.
Ability
Passive
Affects
Enemies
Damage
Physical
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%
Partially usable by illusions. The amount of mana burned is reduced for illusions.

Notes:

  • 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.


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.
  • Purge 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 minimap 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 + 20/30 agility will equate to 65/75 additional physical damage per attack.
Riki icon.png
Riki
  • Purge 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
Spectre
  • 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.
  • Purge allows Spectre to slow enemies she catches with Reality icon.png Reality.

Others[edit]

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 level 25 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
Medusa
  • 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.
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 again attack them.

Tips[edit]

  • 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 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 a 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.

Trivia[edit]

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