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 spell 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 and steals intelligence, meaning that if he gains an advantage in a match he deals constant, colossal damage which cannot be decreased or resisted except with total spell immunity and gets stronger with each hit. He and his allies enjoy more-or-less unlimited mana because of his Essence Aura, which gives them a chance to replenish a percentage 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 the target enemy. His ultimate, Sanity's Eclipse, can instantly deal colossal area-of-effect damage against his enemies based on how much greater his intelligence is than theirs.


Outworld Devourer Harbinger, the Outworld Devourer
Play "Their sanity I'll shatter; their dreams of conquest I'll destroy."
Role: Carry Carry / Nuker Nuker / Disabler Disabler
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
Can be disjointed. Not blocked by Linken's Sphere. Does not pierce spell immunity. Play
Arcane Orb icon.png
Enemies / Self
Adds extra pure damage to Outworld Devourer's attacks, based on his remaining mana pool. Steals 1/2/3/4 intelligence for 80 seconds per hit when attacking an enemy hero. 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

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 separate 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.
  • Steals intelligence after applying its damage, so newly increased mana pool does not affect the attack's damage.
  • Also causes attacks to temporarily remove 12/24/36/48 mana on the target. This mana loss is applied after the damage and before the intelligence steal.
  • When the target loses the debuff, it first regains the removed mana, and then regains its intelligence.
  • Outworld Devourer himself only gains or loses stolen intelligence, without gaining or losing additional mana like the targets. He keeps his current mana percentage.
  • Cannot reduce enemy intelligence below 0, but Outworld Devourer always gains the full amount of intelligence, no matter how much the target has left.
  • Effectively reduces the enemy hero's max mana pool by 12/24/36/48, mana regeneration by 2/4/6/8%, spell damage by 0.07%/0.14%/0.21%/0.29%, and if it is an intelligence hero, attack damage by 1/2/3/4 per cast.
    • Vice versa, effectively increases Outworld Devourer's max mana pool, mana regeneration, spell damage, and attack damage by the same amount per cast on an enemy hero.
  • Places 1 debuff on attacked targets and 1 buff on Outworld Devourer, which show the number of current stacks (a number is visible on the icons).
    • The stacks' durations are independent from each other. Successive casts do not refresh previous stacks' durations.
  • Upon death, the dying hero's intelligence restores back to its normal values, while the other party keeps the changed intelligence values for the remaining duration.

Astral Imprisonment
Blocked by Linken's Sphere. Does not pierce spell immunity. Play

Buff or Debuff, based on the target's alliance Astral Imprisonment Prison: Undispellable.
Locked away in the pocket between this world and the Outworld, victims realize their infantile knowledge and mortality.


  • The damage is applied at the end of the duration and affects the imprisoned unit as well, if it was an enemy.
  • 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.
  • The -disablehelp command prevents an allied Outworld Devourer from casting this spell on you.

Essence Aura
Can be used by illusions. Disabled by Break. Pierces spell immunity. Play
Essence Aura icon.png
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: 900
Proc Chance: 40% (Talent 55%)
Max Mana Restored: 10%/15%/20%/25%
Mana Bonus: 125/200/275/350
Buff Essence Aura Effect: Undispellable.
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 does not proc on any item abilities.
  • On average, restores 4%/6%/8%/10% of caster's maximum mana per cast.

Sanity's Eclipse
Does not pierce spell immunity. Play
Sanity's Eclipse icon.png
Target Area
Unleashes a psychic blast that removes 40% of the mana from affected heroes, while also damaging them based on the difference between the affected hero's intelligence and Outworld Devourer's. If an enemy has the same or higher intelligence than Outworld Devourer, Sanity's Eclipse will not cause damage. Sanity's Eclipse can hit units trapped by Astral Imprisonment.
Cast Animation: 0.25+0.4
Cast Range: 700
Effect Radius: 375/475/575
Intelligence Difference Damage Multiplier: 8/9/10 (Talent 10/11/12)
Max Mana Removed: 40%
Cooldown symbol.png 160
Mana symbol.png 175/250/325
When an Outworld crystal ruptures, cataclysmic energies are released, and the reverberations of this power are felt interdimensionally.


  • Applies the mana loss first, and then the damage.

Recommended items[edit]

Starting items:

  • Null Talisman icon.png Null Talisman provides cheap compact stats for a mid-laner with low base damage.
  • Faerie Fire icon.png Faerie Fire gives a little bit of extra damage, and can be consumed to turn the tide in a close fight.
  • Tango icon.png Tango restores health to stay in lane.


  • Boots of Speed icon.png Boots of Speed will make Outworld Devourer even faster, which is important in middle lane.
  • Bottle (Full) icon.png Bottle and/or Magic Wand icon.png Magic Wand gives more sustainability during the laning stage.
  • A second Null Talisman icon.png Null Talisman is a common item for intelligence heroes during the laning phase.

Core items:

  • Power Treads icon.png Power Treads gives more attack speed and intelligence to cast more Arcane Orbs.
  • Force Staff icon.png Force Staff gives escape mechanism as well as good stats and upgrades later into Hurricane Pike icon.png Hurricane Pike, which is the most important mid-game item for Outworld Devourer.

Situational items:

  • Black King Bar icon.png Black King Bar protects against most disables and nukes, buying Outworld Devourer the time to stack intelligence and use his ultimate more effectively.
  • Blink Dagger icon.png Blink Dagger increases his mobility even more, allowing Outworld Devourer to blink to safety after a self-cast Astral Imprisonment.
  • Shiva's Guard icon.png 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 icon.png Scythe of Vyse provides him with both additional intelligence and a silencing disable, giving him more time to deal damage with his Arcane Orb.
  • Octarine Core icon.png Octarine Core gives the most mana in a single item, as well as immense survivability for Outworld Devourer by lifestealing from his Arcane Orb and his other spells. It also allows Sanity Eclipse to be used more frequently.
  • Moon Shard icon.png Moon Shard gives a high attack speed boost, allowing to deal more damage in battles and steal intelligence faster.
  • Veil of Discord icon.png Veil of Discord provides some much-needed regen and armor, and is a cheap way to amplify the damage of his ultimate and Astral Imprisonment.
  • Rod of Atos icon.png Rod of Atos will provide him with additional health and intelligence, as well as the ability to root against a single target.
  • Orchid Malevolence icon.png 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. Also builds later into Bloodthorn icon.png Bloodthorn.
  • Refresher Orb icon.png Refresher Orb is one of the strongest late-game items on Outworld Devourer, as it allows Sanity's Eclipse, as well as items like BKB and Hex to be cast twice, which can be devastating in teamfights.
  • Aghanim's Scepter icon.png Aghanim's Scepter provides all round stat, health and mana boost. Extra Astral Imprisonment and it's range improvement provides an additional disable.


  • 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. Mobility items are good.
  • 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.
  • Arcane Orb icon.png Arcane Orb steals Intelligence from Heroes it hits. It is wise to build attack speed so you can release more attacks in a teamfight, so that more Intelligence can be stolen in a shorter span of time.
  • Astral Imprisonment icon.png Astral Imprisonment deals damage at the end of the duration, preventing Heroes with Blink Dagger icon.png Blink Dagger from escaping. However, use this ability with caution on Heroes with natural escape mechanisms, like Anti-Mage minimap icon.png Anti-Mage or Morphling minimap icon.png Morphling, as the 4 second period would be enough to make them decide where to go and quickly move away to safety.
    • The damage would also be useful against creep waves. Use the ability on a creep last to be targeted, but surrounded by enough creeps so that after the duration, the damage would hit as many creeps as possible.
    • Other uses for it is that it can be used to delay enemy heroes you are laning against, preventing them from getting a last-hit or deny. In a teamfight, cast this on their carry or initiator, as this could lock out their main damage dealer and/or disabler from retaliating to your team's initiation.
    • 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 minimap icon.png 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 four second duration at level 1, it could be wise to level it first at the start of the game to either lock out a lone enemy or make securing runes or ganks easier.
  • Level up Essence Aura icon.png 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. By level 3, Arcane Orb can be kept permanently on autocast, as the mana gained when the aura procs would be enough to keep your mana pool close to full.
  • Casting Sanity's Eclipse icon.png Sanity's Eclipse can prove important when a team fight starts, since it can shut down spell-reliant casters by burning 40% 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 you can deal immense amounts of damage.
  • 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.
  • Other intelligence heroes, most notably Invoker minimap icon.png Invoker Silencer minimap icon.png Silencer and Pugna minimap icon.png Pugna, can render Sanity's Eclipse useless because of their rapid intelligence growth. Instead, focus on using your ultimate against other heroes whose primary attribute is not intelligence.
  • Use Astral Imprisonment to block yourself (or an ally) from spells; slow-moving projectile spells like Gyrocopter minimap icon.png Gyrocopter's Homing Missile or Sven minimap icon.png Sven's Storm Hammer give you plenty of time to block them. Lethal spells like Sand King minimap icon.png Sand King's Epicenter or even Lion minimap icon.png 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 minimap icon.png Disruptor's Kinetic Field, Naga Siren minimap icon.png Naga Siren's Ensnare, or Chen minimap icon.png Chen's Penitence, can be decreased in time thanks to Astral Imprisonment's 4 second invulnerability period.
  • Pugna minimap icon.png 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 minimap icon.png Phantom Lancer or Chaos Knight minimap icon.png Chaos Knight to fight you. Summoned units also take additional damage, turning units like Enigma minimap icon.png Enigma's eidolons and Nature's Prophet minimap icon.png Nature's Prophet's treants into easy gold.
  • Outworld Devourer counters Anti-Mage minimap icon.png 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 minimap icon.png 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" and "Outhouse Decorator".
  • Outworld Devourer has lines for carrying two, three or even four 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.
