Harbinger the Outworld Devourer is a ranged intelligence hero who qualifies as a carry, though unlike traditional carries, he excels against high-armor targets whilst being crippled by magic immunity. With Arcane Orb, his damage output is reliant on his intelligence attribute and the size of his mana pool, so he must focus more or less exclusively on items which augment them. Though he lacks somewhat in range and has no innate mobility skills, Arcane Orb deals Pure damage, meaning that if he gains an advantage in a match he deals constant, colossal damage which cannot be decreased or resisted except with total magic immunity. He and his allies enjoy more-or-less unlimited mana because of his Essence Aura, which gives them a chance to replenish a quarter of their mana upon casting a spell. With Astral Imprisonment, Harbinger can render himself or an ally invulnerable for a short period of time, or disable (and steal Intelligence from) the target enemy. His ultimate, Sanity's Eclipse, can instantly deal colossal area-of-effect damage against his enemies when his intelligence is higher than theirs.


Outworld Devourer Harbinger, the Outworld Devourer
Play "Their sanity I'll shatter; their dreams of conquest I'll destroy."
Role: Pip carry.png Carry
Lore: One of a lordly and magisterial race, Harbinger prowls the edge of the Void, sole surviving sentry of an outpost on the world at the rim of the abyss. From this jagged crystalline Outworld, forever on guard, he has gazed for eternities into the heavens, alert for any stirring in the bottomless night beyond the stars. Imprinted deep in the shining lattices of his intellect lies a resonant pattern akin to prophecy, a dark music implying that eventually some evil will wake out there, beyond the edges of creation, and turn its attention to our world. With his whole being focused on his vigil, Outworld Devourer paid little attention to events closer in to the sun. But at last the clamor of the Ancients, and a sense of growing threat from within as well as without, sent him winging sunward to visit the plains of war. Harbinger's place in our own prophecies is unambiguous: he must be considered an omen of worse things to come. But his arrival in itself is bad enough.

Arcane Orb
Unique Attack Modifier. Blocked by Spell Immunity. Not blocked by Linken's Sphere. Play
Arcane Orb icon.png
Ability Affects Damage
Autocast Enemies Pure
Adds extra pure damage to Outworld Devourer's attacks, based on his remaining mana pool. Arcane Orb also does bonus damage to summoned units and illusions.
Cast Range: 450
Current Mana as Damage: 6%/7%/8%/9%
Summons & illusions Extra Damage: 100/200/300/400
Mana 100
Harbinger's outworldly knowledge allows it to tap into the ebb and flow of all spiritual energy, infusing it into his being.


  • Deals its damage in a seperate instance, so it is unaffected by any attack modifying effect.
  • Deals its damage before the attack damage is applied, but still depends on the attack hitting the target.
  • Checks Outworld Devourer's mana pool upon projectile hit, so increasing or decreasing his mana pool while the projectile flies does affect its damage.

Astral Imprisonment

Ability Affects
Target Unit Heroes
Places a target allied or enemy hero into an astral prison. The hidden hero is invulnerable and disabled. When cast on an enemy Hero, Harbinger temporarily steals intelligence from that hero.
Cast Time: 0.25+0.4
Cast Range: 500
Intelligence Steal: 4/7/10/13
Duration of Steal: 50
Duration of Imprisonment: 1/2/3/4
Cooldown 18/16/14/12 Mana 120/140/160/180
Locked away in the pocket between this world and the Outworld, victims realize their infantile knowledge and mortality.


  • Can be cast on self or allied heroes, without stealing their intelligence.
  • When cast on an enemy, it steals their intelligence directly upon cast.
  • Effectively reduces the enemy's max mana pool by 52/91/130/169, mana regeneration by 0.16/0.28/0.4/0.52 and if it's an intelligence hero, attack damage by 4/7/10/13.
  • On the other side, Outworld Devourer's max mana pool is increased by 52/91/130/169, mana regeneration by 0.16/0.28/0.4/0.52 and attack damage by 4/7/10/13.
  • Ontop of that, it also reduces the enemy's current mana pool by 52/91/130/169 right before reducing their intelligence, while increasing Outworld Devourer's by the same amount.
  • When the target gets its stolen intelligence back, it also gets its current mana increased and Outworld Devourer reduced by the same amount.
  • Upon death, the dying hero's intelligence restores to back to its normal values, while the other partie keeps the changed intelligence values for the remaining duration.
  • The red ring expanding at the center of the visual effects indicates the duration of the imprisonment. The red ring is visible to allies only.
  • However, it is only adapted to level 4, means at level 1 it expands for 1/4, on 2 for 1/2, on level 3 for 3/4 and only at level 4 in expands up to the edge.
  • The -disablehelp command prevents an allied Outworld Devourer from casting this spell on you .

Essence Aura

Essence Aura icon.png
Ability Affects
Aura Allied Heroes
Whenever nearby allied Heroes or Outworld Devourer itself casts a spell, it gains a chance to restore a percentage of its mana pool. Outworld Devourer also passively gains a bonus to its base mana pool. Several skills with no cooldown and toggled spells cannot trigger Essence Aura.
Radius: 1000
Proc Chance: 40%
Max Mana Restored: 10%/15%/20%/25%
Base Mana Bonus: 75/150/225/300
The crystals of the Outworld produce arcane power, and the Harbinger channels it into the world of mortals.


  • The aura's buff lingers for 0.5 seconds.
  • Restores the mana right after the spell is cast.
  • Essence Aura icon.png Essence Aura generally does not trigger for spells and sub-spells with no cooldown. So it does not trigger for the following abilities:
  • Does not trigger on any active attack modifier, except for Arcane Orb icon.png Arcane Orb.
  • Every other spell (including every not listed sub-spells) can trigger the aura.

Sanity's Eclipse
Not blocked by Spell Immunity. Not blocked by Linken's Sphere. Play
Sanity's Eclipse icon.png
Ability Affects Damage
Target Area Enemy Heroes Magical
Unleashes a psychic blast that damages enemy heroes based on the difference between the affected the hero's Intelligence and Outworld Devourer's. If the difference in intelligence is less than the threshold, the affected hero will lose 75% of their current mana. Should an enemy hero have the same or higher Intelligence than Outworld Devourer, Sanity's Eclipse will have no effect. Sanity's Eclipse can hit units trapped by Astral Imprisonment.
Cast Time: 0.25+0.4
Cast Range: 600/650/700 (700/750/800*)
Effect Radius: 375/475/575
Intelligence Difference Damage Multiplier: 8/9/10 (9/10/11*)
Intelligence Difference Threshold: 10/30/50
Cooldown 160 Mana 175/250/325
Not blocked by Spell Immunity. Damage is blocked, mana loss is not.
Can be Improved by Aghanim's Scepter (* shows the improved values). Increases damage multiplier, casting range and causes the ability to always trigger the mana loss on all heroes it damages.
When an Outworld crystal ruptures, cataclysmic energies are released, and the reverberations of this power are felt interdimensionally.


  • Affects units under the effect of the most recent Astral Imprisonment icon.png Astral Imprisonment cast by Outworld Devourer.
  • Applies the damage first, and then the mana loss.
  • This means that enemies with same or higher intelligence than Outworld Devourer are still fully unaffected by it.

Recommended Items


  • Due to his ultimate, Sanity's Eclipse, Outworld Devourer needs to outmatch his enemies' intelligence. Boosting intelligence also boosts his mana pool, increasing the power of Arcane Orb, the main source of his damage.

Starting Items:

Early Game:

  • Null Talisman gives him additional Intelligence as well as attack damage.

Core Items:

  • Power Treads gives him additional attributes and more attack speed.
  • A Force Staff provides additional health regeneration and a proper escape mechanism, which he lacks.
  • A Town Portal Scroll will help him travel around the map faster, so that he could be in the action sooner.

Situational Items:

  • Rod of Atos will provide him with additional health and Intelligence, as well as a slowing ability against a single target.
  • Orchid Malevolence gives him even more Intelligence and attack speed, and also gives him a Silence ability that also amplifies his damage for the time period.
  • Shiva's Guard will give him more armor for survivability, as well as more intelligence. The slow also helps him either chase, or escape.
  • Scythe of Vyse provides him with both additional Intelligence and a silencing disable, giving him more time to deal damage with his Arcane Orb.
  • Refresher Orb gives him bonus health and regeneration, as well as allowing him to cast Astral Imprisonment and Sanity's Eclipse twice.
  • Black King Bar will help Harbinger protect against lethal disables, as well as most damage-heavy abilities.
  • Aghanim's Scepter gives him even more attributes, as well as improve his ultimate. The additional attribute bonus can also aid his tankiness.



  • One of Harbinger's significant weaknesses is his fragility. Avoid taking in too much damage; if so, you will miss out on potential gold and experience, as well as put your team in danger by not dealing the needed extra damage against your enemies. Try to fight in the sidelines, or when your enemies are too busy to attack you. His defense can be boosted through items, but make sure not to deprive him of too much intelligence.
  • Try to level up as much as possible in the early stages of the game, be it from farming or killing other heroes. The more you advance in level, the more Intelligence and gold you will receive. The more Intelligence and gold you receive, the better you will dominate in the mid and later game. OD is extremely powerful in the later game, provided he farms well in the laning phase.
  • Level up Harbinger's Essence Aura fairly quickly so that he can solve his mana problems. Essence Aura can also make a good support ability for your allies, especially if they rely heavily on casting spells.
  • Astral Imprisonment is Harbinger's disabling ability, and can be used in numerous ways:
    • Early in the game, it can be used to harass against heroes you are laning against. It is easiest to land against melee heroes, but effective against most heroes (though sometimes for differing reasons.)
      • Strength and Agility heroes are good targets, since Astral Imprisonment steals intelligence from their already low supply. They can repeatedly be disabled to the point that they are unable to cast spells (the steal stacks three to five times depending on its level, stealing a total of 12/18/32/50 intelligence).
      • Intelligence heroes, on the other hand, lose damage as well as have their mana pool lowered, while Harbinger increases his. Harbringer's base attack damage will also increase by a good amount if you use Astral Imprisonment a few times, which makes last hitting in the mid lane very easy against some heroes.
    • It can be used to delay enemy heroes you are laning against, preventing them from getting a last-hit or deny.
    • It can also be used to buy time, be it escaping or trying to chase an enemy. While escaping, you can cast it on yourself or any dying ally to shift the enemy's focus away. While chasing, you can step ahead of the imprisoned enemy's path and make it harder for them to escape.
    • Use Astral Imprisonment carefully against your enemies when your allies are present in the team fight. Using it too much in these situations can potentially block your allies' spells, especially if they are channeling disables (i.e. Pudge Pudge's Dismember). Use it when your teammates are out of disables, or when the enemies are in the process of escaping. As well, try to target other units that are currently not disabled or crippled by your teammates.
    • Because of its utility, versatility, and intelligence steal, Astral Imprisonment is usually taken first before most other abilities.
  • When Harbinger's Essence Aura is high enough (at least Level 3), you can keep casting Arcane Orb against enemy targets to restore his mana right away if depleted.
  • Casting Sanity's Eclipse can prove important when a team fight starts, since it can shut down spell-reliant casters by burning 75% of their mana, as well as soften strength and agility heroes. Keep in mind that your intelligence must be at least marginally higher than theirs so that the effects can work.
  • Outworld Devourer has no reliable escape until he gets a Force Staff. Frequent early ganks can put him at a severe disadvantage. Proper warding (by team mates) and map awareness are key.
  • In team fights, Astral Imprisonment can be used to shut down a key enemy character, such as a durable carry like Wraith King, so your team can focus on squishier supports. As Sanity's Eclipse can be used on imprisoned enemies, it may be preferable to initiate by imprisoning and immediately ulting the same target.

Hero Tips

  • Other intelligence heroes, most notably Silencer icon.png Silencer and Pugna Pugna, can render Sanity's Eclipse useless because of their rapid intelligence growth. Instead, focus on using your ultimate against other heroes whose main attribute isn't intelligence.
  • Use Astral Imprisonment to block yourself (or an ally) from spells; slow-moving projectile spells like Gyrocopter icon.png Gyrocopter's Homing Missile or Sven Sven's Storm Hammer give you plenty of time to block them. Lethal spells like Sand King Sand King's Epicenter or even Lion Lion's Finger of Death can be rendered useless with good timing. Spells that cripple your movement and make you vulnerable for attack, like Disruptor icon.png Disruptor's Kinetic Field, Naga Siren Naga Siren's Ensnare, or Chen Chen's Penitence, can be decreased in time thanks to Astral Imprisonment's 1/2/3/4-second invulnerability period.
  • Pugna Pugna's Nether Ward will count Arcane Orb as a spell cast, so make sure to destroy it before liberally using Arcane Orb against other enemy heroes.
  • Arcane Orb deals bonus damage against illusions, making it harder for illusion-reliant heroes like Phantom Lancer Phantom Lancer or Chaos Knight icon.png Chaos Knight to fight you. Summoned units also take additional damage, turning units like Enigma Enigma's eidolons and Nature's Prophet Nature's Prophet's treants into easy gold.
  • Outworld Devourer counters Anti-Mage Anti-Mage, since he can regain mana instantly from Essence Aura just by auto-casting with Arcane Orb. As well, the pure damage goes through his Spell Shield.
    • However, in certain situations when Outworld Devourer is silenced or stunned for an extended period of time, Anti-Mage's Mana Break icon.png Mana Break and Mana Void icon.png Mana Void, especially in combination with Manta Style icon.png Manta Style and other heroes with mana drain like Nyx Assassin Nyx Assassin, can still use Outworld Devourer's massive mana pool against him.


  • Outworld Devourer was originally called Obsidian Destroyer in DotA. Obsidian Destroyer was based off of two units in Warcraft III: Frozen Throne; the Obsidian Statue, and its alternate form, the Destroyer.
  • Outworld Devourer's original Dota 2 name was "Outworld Destroyer". This was changed to "Outworld Demolisher" on the Test Client, but due to community outcry, it was changed again when it arrived on the main client to his current name, "Outworld Devourer". Due to such name changes, there are many community humour names in circulation, such as "Outworld Developer".
  • Outworld Devourer has lines for carrying two even three Aghanim's Scepter. The reason for this is because in Dota 1 early development Aghanim's Scepter was made using Mystic Staff and a Soul Booster giving 500 mana and 30 int, which helped Outworld Devourer tremendously.
