Pit of Malice
For the spin-off game, see Dota Underlords.

Through a Fiend's Gate comes the legions of the Abyssal Horde, marching out of their subterranean city with intent to conquer the nations above. Amidst the invaders stood Vrogros, the demonic hulk who conjured and rained apocalyptic Firestorms from the sky, engulfing towns and villages in emerald flame. Immolated enemies are held paralyzed in his spiteful, Malicious Grip. Feasting upon the carnage of battle, gaining strength as foes perish around him, causing their attacks to Atrophy by his very presence, delivering bloody retribution to any who would defy the will the Underlord.

Underlord minimap icon.pngVrogros, the Underlord
▶️ "Nothing can stop us. Nothing can slow our march. And when we have arrived, all will burn."
Neither myth nor song exist to tell of their coming.

Deep below the surface of the world lay unknown wonders and horrors. Down and down again, well beneath the slithering magma fields and simmering roots of dormant volcanoes stands the obsidian city of Aziyog, its incomparable stonework spanning an endless cavern. Within honeycomb walls mortared with the bones of countless slaves lies the domain of the Abyssal Horde, and their brutal underlord Vrogros.

Armed by the monstrous forgemasters of his kind and well-practiced in the arts of the Dark Rift, Vrogros is able to conjure forth flame and crippling malice through the twist between worlds. He seeks always to expand his holdings, destroying or enslaving all he encounters. Yet the lands offered by the subterranean realm are few, and so his sights have turned upward. By his command the first waves of abyssal invaders have already marched through the rift, a few doomed legions meant merely to test the might of nations above. Now, as his full force readies itself for unending conquest, Vrogros himself steps into a sunlit world to announce his coming reign. Those who face the Underlord will bow and pay tribute, or be crushed where they stand.
Pit Lord, Azgalor

Modifiers [?]
The flames of conquest blaze forth from the darkest depths of the abyss.


  • The visual and audio effects at the targeted area during the cast time are visible and audible to allies only.
  • Creates 6 (Upgradable by Aghanim's Shard. 9) waves in 1-second (Upgradable by Aghanim's Shard. 0.75-second) intervals, starting immediately upon cast, resulting in duration of 5 (Upgradable by Aghanim's Shard. 6) seconds.
  • Despite the visual effects, the damage is applied instantly, and not upon the waves landing.
  • On each wave, Firestorm first applies the damage, then the debuff.
    • Does not place the burn debuff on Roshan icon.png Roshan, but does apply the wave damage.
  • The burn debuff deals damage in 1-second (0.75-second) intervals, starting immediately as the debuff is applied, resulting in 3 instances.
    • The burn debuff does not stack per interval. Each interval refreshes its duration, resulting in 8 (Upgradable by Aghanim's Shard. 11) possible instances.
  • Can deal up to 150/240/330/420 + 8%/16%/24%/32% (Talent 16%/24%/32%/40%) of maximum health as damage (before reductions) when all waves hit.
    • With Aghanim's Shard icon.png Aghanim's Shard, it can deal up to 225/360/495/630 + 11%/22%/33%/44% (Talent 22%/33%/44%/55%) of maximum health as damage.

Aghanim's Scepter Upgrade:
Slows enemy movement speed in the Pit of Malice.
Modifiers [?]
Twisting into the seams of reality itself, Vrogros' manifest hatred paralyzes those who defy his will.


  • The visual and audio effects at the targeted area during the cast time are visible and audible to allies only.
  • Roots the targets, preventing them from moving and casting certain mobility abilities.
    • Fully affects invisible units and units inside the Fog of War.
    • Provides True Sight over the targets.
  • The root is applied periodically on every enemy within the area.
    • However, the hidden modifier prevents them from being continuously rooted for the whole duration.
    • This hidden modifier is applied on every unit within the area which does not have the modifier yet. The modifier lasts for 3.6 seconds.
    • Whenever the modifier expires, enemies get instantly rooted again, and then the hidden modifier is reapplied again.
    • This means that Pit of Malice does not root every unit within the area in set intervals. Each unit is rooted every 3.6 seconds based on when they entered the area.
    • The hidden modifier does not disappear upon leaving the area. Quickly leaving and re-entering does not result in an instant-root.
    • All pits share the same modifier, therefore the root does not stack — once rooted, the unit becomes immune to all other pits until the modifier wears off.
  • Can root a unit up to 4 times if it stays within the area for the full duration, resulting in a total root time of 4.8/5.6/6.4/7.2 (Talent 7.4/8.2/9/9.8) seconds.
  • Creates a distinct visual effect around, and plays a distinct sound on affected heroes and illusions, but not around other affected units.
  • Aghanim's Scepter icon.png Aghanim's Scepter adds a 400 radius aura to the center of Pit of Malice, which slows enemy movement speed.
    • The debuff lingers for 0.5 seconds.
    • Acquiring Aghanim's Scepter immediately updates all current active instances.

Atrophy Aura
Can be used by illusions. Partially disabled by Break. Does not pierce spell immunity. ER
Atrophy Aura icon.png
Enemies / Self
Nearby enemy units are weakened, losing a portion of their base damage. If an enemy dies while under this effect, Underlord gains temporary bonus damage.
Radius: 900
Attack Damage Reduction: 5%/15%/25%/35% (Talent 20%/30%/40%/50%)
Attack Damage Bonus per Hero Death: 30/35/40/45
Attack Damage Bonus per Non-Hero Death: 2/4/6/8
Buff Duration: 30/45/60/75
Aura Linger Duration: 0.5
Talent Allied Bonus Percentage: 50%
Partially disabled by Break.
Break Notes:
Disables the aura and prevents gaining new stacks.
Existing stacks still provide bonus attack damage.
Can be used by illusions.
Illusion Notes:
Illusions bestow the aura.
When an enemy unit dies around an illusion which is or was under Underlord's control, the damage is granted to Underlord.
If the source of the illusion is an enemy or allied ability, the damage is granted to the illusion, although the illusion cannot make use of it.
Modifiers [?]
To merely stand in the presence of the Underlord is to feel the conviction of battle sapped from one's soul.


  • Reduces the main attack damage of affected units. Bonus attack damage is not reduced.
    • The aura does not affect invulnerable or hidden units, and its debuff lingers for 0.5 seconds.
    • Does not affect enemies which have no vision over Underlord.
    • However, Underlord still gains attack damage from dying enemies within the radius, despite the debuff not being present.
  • Grants flat bonus attack damage as long as the dying enemy unit was affected by the debuff, regardless of how it dies.
  • A status buff is visible on the HUD, showing the current amount of bonus attack damage the aura currently grants.
    • Underlord's weapon also glows stronger with green particle effects the more damage stacks he has.
  • The Atrophy Aura ally hero bonus Talent talent grants 50% of the bonus attack damage to all allied heroes, including illusions, clones, and creep-heroes within its radius.
    • However, the bonus attack damage is not provided by an aura, it is placed as an expiring buff on allies.
    • It uses the same modifiers for allies as it does for Underlord, so they work exactly the same.
    • Affected allies gain 15/17.5/20/22.5 bonus attack damage per dying hero and 1/2/3/4 bonus attack damage per dying non-hero units.

  • Underlord is named Azgalor, the Pit Lord in DotA.[1]
    • His title, Pit Lord, was changed to avoid possible copyright infringements with Blizzard Entertainment, since the Pit Lords are a race of demons in the Warcraft universe.[2]
    • His name, Azgalor, was also changed for the same reason. Azgalor was a character from the Warcraft universe as well, who served one of the main antagonists of the Warcraft universe as a well known commander.[3]
    • According to the Bastion Announcer, ▶️ "Pyre Lord" was also a proposed name for Underlord.
    • Up until the June 23, 2016 Patch, Underlord's title was "Abyssal Underlord". While the rationale of dropping "Abyssal" is unclear, it may have been to prevent confusion with the shorthand terminology of Abyssal Blade.
  • Underlord had been developed since 2012; he already had a beta model, placeholder ability icons and fully finished and working abilities. He could also be spawned in lobbies with cheats enabled for a short while before it was disabled.
    • This suggests that his release was originally planned much earlier (as a comparison, all other heroes were released shortly after their files were added to the game), but was delayed for reasons unknown.
  • Before his release, Underlord was showcased at the All-Star match of The International 2016, played by N0tail. He originally picked Sand King​, but a bit after the start of the game, SirActionSlacks replaced his pick by Underlord.
  • The line Underlord says after killing Bane minimap icon.png Bane, ▶️ "You have my permission to die.", is a reference to the famous line "When Gotham is ashes, you have my permission to die", said by the villain Bane from the movie The Dark Knight Rises.
  • Underlord's line when casting Dark Rift, ▶️ "Hold on to your butts!", was spoken by Samuel L. Jackson's character Ray Arnold in the movie Jurassic Park (1993).
  • Underlord was the final DotA hero ported over, before Dota 2 began to feature original heroes.
