Feedback (Mana Burn) - an effect that burns an opponent's mana.

Most of the heroes become weaker if they lack of mana.

If you have a passive mana burn ability or an enemy spent his mana, there won't be any extra damage from mana burn.

Features of some abilities

    Damage: 0.6/0.85/1.1
  • keeper_of_the_light Keeper of the Light -  Mana Leak
    If the enemy loses all of its mana, it will be stunned.
    Stun duration: 1.5/2/2.5/3
  • Outworld Devourer Outworld Devourer - Arcane Orb Arcane Orb
    Adds extra pure damage to Outworld Devourer's attacks, based on his remaining mana pool.

  • hp_i_mp__zdorove_i_mana Medusa - Mana Shield Mana Shield
    Creates a shield that absorbs 50% of the incoming damage by using Medusa's mana.

Mana burn is specially effective against hp_i_mp__zdorove_i_mana Medusa and Wraith King Wraith King. Outworld Devourer Outworld Devourer almost always has mana and you can all the time deal extra damage with your passive mana burn ability.



hp_i_mp__zdorove_i_mana Diffusal Blade

Feedback (passive)

  • Each attack burns 20 mana (36 if it is of the 2nd level) and deals the same damage;
  • It is a Unique Attack Modifier, and does not stack with other Unique Attack Modifiers.
    It does not stack with Anti-Mage Anti-Mage -  Mana Break.
  • Mana burn effects on melee illusions.
     Manta Style
    Naga Siren Naga Siren -  Mirror Image
    Phantom Lancer Phantom Lancer - all abilities
    Terrorblade Terrorblade - Conjure Image Conjure Image
    Chaos Knight Chaos Knight - Phantasm Phantasm
    Spectre Spectre - Haunt Haunt


Must-have for  Naga Siren Naga Siren, Phantom Lancer Phantom Lancer.

It is good for  Spectre Spectre.

It can be good for Chaos Knight Chaos Knight, if enemy heroes purchased  Ghost scepeter.

There more suitable items for Terrorblade Terrorblade, he will be metamorphosed in important fight so mana drain won't effect on illusions.
