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, to conceal herself and her spiderlings in an area, 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 invisibility/added HP 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 Black Arachnia, the Broodmother
Play "I've promised you to my children."
Role: Pip pusher.png Pusher / Pip carry.png Carry / Pip tank.png Escape
Lore: 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.

Spawn Spiderlings
Blocked by Magic Immunity. Play
Spawn Spiderlings icon.png
Ability Affects Damage
Target Unit Enemies Magical
Broodmother injects her young into an enemy unit, dealing damage. The spiderlings will hatch if the target is killed while under this influence.
Range: 700
Damage: 75/150/225/300
Count: 1/2/3/4
Cooldown 10 Mana 120
Black Arachnia continues to raise her young, even amidst the field of combat. The brood quickly learns how to support their mother.


  • Units from which the Spiderlings spawn leave no corpse on death.
  • If the target is killed within 2 seconds of being hit by this ability, regardless of what the killer is, the Spiderlings will spawn (This includes denying an "infected" ally or committing suicide).
  • Units killed by Spiderlings will then give birth to Spiderites, smaller and less powerful versions of the Spiderlings.

Spin Web
Cannot be used by illusions. Play
Spin Web icon.png
Ability Affects
Target Point
Throws out a web that renders Broodmother invisible, grants a passive movement speed increase, gives free movement, and boosts regeneration while in its vicinity. Free movement is disabled for 3 seconds if damage is taken. Webs never expire. When the maximum limit of webs is exceeded, the oldest web disappears.
Range: 1000
Radius: 900
Maximum Webs: 2/4/6/8
Bonus Health Regeneration: 2/4/6/8
Bonus Movement Speed: 20%/25%/30%/35%
Cooldown 30 Mana 50
Weaving a bed of silken fibers, Arachnia's web both protects her and her offspring, as well as giving advancing opponents a sense of foreboding.


  • Has an invisibility fade time of 2 seconds, but invisibility is instantly lost outside the web.
  • Movement speed and health regeneration are instantly granted and lost when moving in or out of the web.
  • Also affects Spiderlings and Spiderites.
  • If more webs are spawned than allowed, the oldest one will disappear.
  • Webs are marked by icons on the minimap.
  • She gains unobstructed movement within the web (can walk over cliffs, trees, etc) with no collision box.
  • Spiderlings and Spiderites do not get unobstructed movement.
  • Unobstructed movement is disabled for 3 seconds when she takes damage.
  • Has a 0.4 cast point (slower than default).
  • Broodmother will not be able to become invisible while muted, but will not lose her invisibility if she is already on a web. Other components behave normally.

Duration: 2
Miss Chance: 30%/40%/50%/60%
Move Slow: 10%/20%/30%/40%

Bonus Damage: 60/80/100

Recommended items[edit]

Starting items:

Early-game items:

  • The extra mana burst from Soul Ring allows her to use Spawn Spiderlings icon.png Spawn Spiderlings to harass the lane rival and safely take lasthits.
  • Ring of Basilius provides attribute bonuses as well as an armor aura for extra pushing power and can be upgraded into Vladimir's Offering later on.

Core items:

  • Power Treads provide attack speed and more survivability through additional attribute bonuses.
  • The silence from Orchid Malevolence allows her to kill heroes with escape abilities and/or stuns.
  • Vladimir's Offering provides a useful lifesteal effect on both Broodmother, fully stacking with the effects of her ultimate ability. The bonus armor and attack damage will greatly increase the ability of Broodmother and her spiders to push lanes and towers.

Situational items:

  • Black King Bar's magic immunity synergies with the huge lifesteal from Insatiable Hunger icon.png Insatiable Hunger and makes her very hard to kill.
  • Butterfly offers bonus attack speed, damage, and armor; and the evasion stacks with Incapaciting Bites making you almost impossible to touch.
  • Monkey King Bar is bought to dominate enemies with evasion and the built-in mini-bash can prevent enemies from escaping with a Town Portal Scroll.
  • Radiance provides useful area damage that Broodmother can easily apply while invisible and/or unreachable both to push lanes faster and to harass incautious enemy heroes.
  • Assault Cuirass will boost the attack speed and armor of Broodmother and her spiders.



  • Spin Web and Spawn Spiderlings should almost always be maxed first, before points are put into any other ability. Both Incapacitating Bite and Insatiable Hunger are only useful once Broodmother has gotten her farm.
  • Going into a solo lane is a viable option for Broodmother as webs give her the survivability and the pushing power from the spiderlings can overwhelm a lane without need of her being babysat by an additional hero.
  • Spawn Spiderlings acts as a ranged nuke, and is very useful for killing weak enemies that are fleeing.
  • Soul Ring is a great item to have on her as the instant mana boost gives her the ability to spawn more spiderlings and the HP regen from the webs can cover for the loss of HP from the Soul ring
  • Going right into a Black King Bar is a good choice as the combination of magic immunity and the powerful lifesteal from Insatiable Hunger makes the Broodmother a very difficult opponent to kill.
  • Casting Spin Web on top of an enemy tower makes it easy to dive in on weak heroes. The regen and movespeed bonus combined with Broodmother's slow is very effective for diving on heroes with no reliable escape or stun.
  • Broodmother is very effective against solitary targets, but against multiple enemies she suffers; as her lifesteal can generally only replenish the damage taken from a solitary foe.
  • A quick Yasha will give her more movement speed to evade ganks and remain a threat for that lane. Then this can be made into a Manta Style which will give her a way to remove dust and confuse the enemy to escape ganks and waste their crowd control spells.
  • Be cautious when the enemy has picked an Earthshaker as Echo Slam will annihilate her if multiple spiderlings are present.
  • Legion Commander's first ability, Overwhelming Odds, scales off how many units are in the AoE. It will destroy her spiderlings and do a huge amount of damage to Broodmother.


  • In her DotA biography, Broodmother's spiderlings originated from her relationship with Anub'arak, the Nerubian Assassin. In Dota 2, Nerubian Assassin was changed to Nyx Assassin Nyx Assassin to avoid copyright issues, thus changing Broodmother's story and severing any ties between them.
  • Broodmother's Fun/Alternate name was Broodmama.
  • One of Broodmother's rarer responses is "some pig", a reference to the children's novel Charlotte's Web.
