Black Arachnia, the Broodmother, is a melee agility hero who is a notably powerful pusher. Her trademark spiderlings, as both an asset and a liability, define her play style. While a possible additional source of income, experience and lane pushes, spiderlings can easily feed opponents when not handled with deft micro and great awareness. Broodmother's abilities allow her to summon those spiderlings to do her bidding and to slow and kill heroes with relative ease if caught off guard, all while staying as elusive as possible with her webs and passives. She spends most of the early game pressuring a lane with little concern, due to her spiderlings and her added health regeneration, but she can also transition into a difficult to kill melee carry, which can dive in on and rapidly kill lone enemies with the right items later on.


Broodmother minimap icon.pngBlack Arachnia, the Broodmother
▶️ "I've promised you to my children."
For centuries, Black Arachnia the Broodmother lurked in the dark lava tubes beneath the smoldering caldera of Mount Pyrotheos, raising millions of spiderlings in safety before sending them to find prey in the wide world above. In a later age, the Vizier of Greed, Ptholopthales, erected his lodestone ziggurat on the slopes of the dead volcano, knowing that any looters who sought his magnetic wealth must survive the spider-haunted passages.

After millennia of maternal peace, Black Arachnia found herself beset by a steady trickle of furfeet and cutpurses, bold knights and noble youths--all of them delicious, certainly, and yet tending to create a less than nurturing environment for her innocent offspring. Tiring of the intrusions, she paid a visit to Ptholopthales; and when he proved unwilling to discuss a compromise, she wrapped the Vizier in silk and set him aside to be the centerpiece of a special birthday feast.

Unfortunately, the absence of the Magnetic Ziggurat's master merely emboldened a new generation of intruders. When one of her newborns was trodden underfoot by a clumsy adventurer, she reached the end of her silken rope. Broodmother headed for the surface, declaring her intent to rid the world of each and every possible invader, down to the last Hero if necessary, until she could ensure her nursery might once more be a safe and wholesome environment for her precious spiderspawn.

Ability Draft Notes
Ability Draft Notes:
Upgradable by Aghanim's Scepter.
Requires drafting Spawn Spiderlings to be unlocked.
The slightest tremor of her web is all Arachnia needs to find her prey.


  • Cannot be cast within the vicinity of another web line. The vector must not overlap with another line to cast.
  • The web line forms over a 2-second duration, during which the line is completely inactive.
  • The web lines are completely invisible to the enemy and cannot be revealed.
  • Once formed, the line can trigger on any enemy hero coming within its area of effect.
  • When triggered, the triggering hero reveives a single debuff that applies all effects.
    • The modifier exposes the target, provides True Sight over them, and slows their movement speed.
    • After 0.25 seconds, the modifier roots the target, preventing them from moving and casting certain mobility spells.
    • This means the root effectively lasts 3.75 seconds.
    • The damage over time starts after this delay as well, and ticks in 1-second intervals, resulting in 4 instances.
    • Can deal a total of 400 damage to the target (before reductions).
  • Once triggered, the web line becomes visible to enemies, and disappears after 4 seconds.
    • This timer is independent from the debuff on the enemy, so removing the debuff does not cause the line to disappear earlier.
    • During this time, other enemy heroes still may get debuffed by the line.
  • The web lines have no set duration, they last until triggered.
    • Exceeding the max allowed number of lines instantly destroys the oldest line.
  • The lines have no form of vision, and are not visible through the Fog of War for anyone.

Complexity: ★★☆
Playstyle: Inhabiting the lava tubes below the caldera of Mount Pyrotheos, Black Arachnia grew tired of recent adventurers stepping on her many offspring. And so, the Broodmother set out to rid the world of every potential intruder, one hero at a time. Paralytic venom drips from her fangs, crippling and blinding her prey with each Incapacitating Bite. Warm bodies make ideal nurseries, a fact not lost on Black Arachnia as she injects her eggs into dying foes to Spawn Spiderlings. Across patches of land she Spins Webs of silken fiber, sheltering herself within to recuperate injuries. Driven by Insatiable Hunger, the Broodmother goes into a feeding frenzy, sucking the vital fluids from wandering heroes to replenish herself for the next spawn cycle.





  • In her DotA biography, Broodmother's spiderlings originated from her relationship with Anub'arak, the Nerubian Assassin (Nyx Assassin minimap icon.png Nyx Assassin). In Dota 2, no relationship between the two heroes exists.
  • Broodmother is sometimes called by her nickname, "Broodmama".
  • Broodmother's response ▶️ "Some pig." is a reference to the children's novel Charlotte's Web.
  • Broodmother's name, Black Arachnia, resembles the name of the character Blackarachnia from the Transformers franchise.
