Does Blade Mail really returns all damage like in its description, or are there any skills whose damage wont be returned?

This is what i want to know:

Will it return:

  • magical damage from AoE attacks?
  • damage from DoT spells?
  • damage from channeled ults like the one of Pudge or Bane?

List of all skills whose damage isn't returned by blade mail, if there are any.

  • as a side note, returned blademail damage is considered pure damage, which can be blocked by BKB

  • @spartacus Erm.. doesn't BKB only give immunity to magic damage? As far as i know pure damage is not considered either physical nor magic and it penetrates both magic resistance/immunity and armor.

    nope, pure damage has the property of ignoring armor/resistance but its actually considered magical. Its pretty easy to test in a custom game.

It does not reflect HP removal abilities, but thats it.

You can find a list of HP removal skills at:


Everything else is being returned as indicated (note that BKB makes you immune to the return damage).

  • AFAIK in DotA 1 there was a threshold. you need at least 1 or 2 dmg to trigger blademail and it can only return a max of 7 or 9000 in one instance. Not sure if they fixed this in DotA 2.

  • Note that abilities such as Pugna's Life Drain are ignored by Blademail, even if it doesn't actually change your max life.
