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, 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 enjoys more-or-less unlimited mana because of his Essence Flux, which can be activated to augment his abilities with a powerful slow when they deal damage. 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 mana pool is than theirs.

▶️ "Their sanity I'll shatter; their dreams of conquest I'll destroy."
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.

  • 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.

  • 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 default duration of the imprisonment. The red ring is visible to allies only.

When an Outworld crystal ruptures, cataclysmic energies are released, and the reverberations of this power are felt interdimensionally.


  • Gains 1 charge whenever Arcane Orb hits an enemy hero or illusion
  • The amount of charges are visible as a number on the status buff on Outworld Devourer. The buff's description tells how much mana it currently grants.
  • Gaining a new charge refreshes the duration of the entire stack.
  • Outworld Devourer keeps his current mana percentage upon gaining or losing the charges.
  • When cast, the damage is based on the maximum mana pool of Outworld Devourer and the hit enemies, not the current mana.
  • The damage only affects enemy heroes and illusions. All other units are completely unaffected.

Recommended items[edit]

Starting items:

  • Null Talisman icon.png Null Talisman provides cheap attributes for a mid hero with low base damage. Outworld Devourer may consider a second Null Talisman later on to boost his intelligence for cheap, giving him an edge in the laning stage.
  • 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.
  • Healing Salve icon.png Healing Salve restores health more quickly than Tangoes while being slightly less cost efficient, however it is better to buy a Salve if you are forced out of last hit range due to spam damage.
  • Iron Branch icon.png Iron Branch gives cheap attributes, and Outworld Devourer can use it with Tango to receive more heal.

Early game:

  • Boots of Speed icon.png Boots of Speed make Outworld Devourer run faster, which is important in middle lane.
  • Magic Wand icon.png Magic Wand gives attributes and sustainability.
  • Hand of Midas icon.png Hand of Midas lets Outworld Devourer scale better, although it may hamper some of your early game power.
  • Drum of Endurance icon.png Drum of Endurance is a cheap and cost effective item that gives Outworld Devourer stats across the board, and greatly helps your teamfight potential. Tyoically, if you plan to farm more before fighting, pick up a Hand of Midas instead, but if you plan to teamfight early, Drum can be amazing.
  • Kaya icon.png Kaya should be bought every game on Outworld Devourer, provides exactly what the hero needs and builds into Yasha and Kaya.

Mid game:

  • Tranquil Boots (Active) icon.png Tranquil Boots allow you to heal quickly between skirmishes. As you effectively have infinite mana, it can be annoying to go back to the fountain or have to shrine just to heal. Outworld Devourer builds almost no health regen items, so Tranquil Boots are excellent. He also has an outstanding base move speed, a move speed talent, and his default build includes Yasha and Kaya, allowing you to move extremely quickly (around 475 ups) with Tranquils active.
  • Yasha and Kaya icon.png Yasha and Kaya provide exactly the stats Outworld Devourer needs, allowing him to move ridiculously fast, attack faster, and have more armor. Sange and Kaya may be considered if the enemy lineup consists of mainly spellcasters, but even then Yasha and Kaya is more attractive.
  • Force Staff icon.png Force Staff provides an escape mechanism as well as good attributes and upgrades later into Hurricane Pike.
  • Blink Dagger icon.png Blink Dagger increases his mobility, allowing Outworld Devourer to blink and escape after a self-cast Astral Imprisonment.
  • Meteor Hammer icon.png Meteor Hammer active is guaranteed by Astral Imprisonment, provided you are not otherwise stunned. This grants extra damage and two seconds of stun to land arcane orbs.

Late game:

  • Hurricane Pike icon.png Hurricane Pike gives attack range and attributes. The active allows Outworld Devourer to position, as well as increasing his attack speed for a number of attacks.
  • 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.
  • Scythe of Vyse icon.png Scythe of Vyse provides him with both additional intelligence and a hex, giving him more time to deal damage with Arcane Orb.

Situational items:

  • Power Treads icon.png Power Treads gives attack speed and intelligence to use more Arcane Orbs. Can be considered as an alternative to Tranquil Boots.
  • 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.
  • Linken's Sphere icon.png Linken's Sphere can be considered as an alternative to Black King Bar if you find yourself heavily focused by single target abilities.
  • 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 increase damages and allows Sanity Eclipse to be used more frequently.
  • Moon Shard icon.png Moon Shard gives a high attack speed boost, allowing him to deal more damage in battles and steal intelligence faster.
  • 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 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 Black King Bar and Scythe of Vyse to be used twice, which can be devastating in teamfights.
  • Aghanim's Scepter icon.png Aghanim's Scepter provides attributes, health, and mana boosts. Extra Astral Imprisonment charges and its range improvement provides an additional disable.


Roles: Carry Carry Nuker Nuker Disabler Disabler
Complexity: ★★☆
Playstyle: Wary of the happenings near the central sun, Harbinger departs from his vigil to take his place on the plains of war. The Outworld Devourer creates an Essence Flux, balancing the tides of mana between him and his opponents. Any being may be placed in Astral Imprisonment, strategically removing them from the field. Glowing spheres fly from his staff, Arcane Orbs that permeate any shield. Looming above his enemies, the Outworld Devourer drops the proverbial hammer, extinguishing the unenlightened with the cosmic force of Sanity's Eclipse.





  • Outworld Devourer was originally called Obsidian Destroyer in DotA. Obsidian Destroyer was based on 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.
