Show/Hide Tooltips

Can imprison a hero, making them invulnerable.
Wary of the happenings near the central sun, Harbinger departs from his vigil to take his place on the plains of war. The Outworld Destroyer creates an Essence Flux, balancing the tides of mana between him and his opponents. Stealing from the minds of those in his Astral Imprisonment, Outworld Destroyer turns raw intelligence into destructive power. Weakening enemies with a barrage of Arcane Energy glowing spheres that permeates any shield. Looming above his enemies, he drops the proverbial hammer, extinguishing the unenlightened with the cosmic force of Sanity's Eclipse.

▶️  Harbinger, the Outworld Destroyer

Aliases:

OD, Harbinger

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 Destroyer 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.

Trivia

• Outworld Destroyer has voice 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 Soul Booster giving 500 mana and 30 intelligence, which helped Outworld Destroyer tremendously.

• In Dota 2, he originally was titled as Outworld Destroyer, changed from the original Obsidian Destroyer.
  • This was likely done for thematic reasons, fitting his Dota 2 lore more.
  • On the January 17, 2013 Patch, he was retitled to Outworld Demolisher on the test client.
  • Due to community outcry, his title was changed again, landing at Outworld Devourer. This happened all on the same day.
  • Due to the many title changes, he gained many humorous community titles such as "Outworld Developer", "Outsourced Developer" and "Outhouse Decorator", and other similar titles with the "OD" acronym.
  • In 7.28, almost 11 years later, his title was once again changed to the original Outworld Destroyer.
  • As a nod to this, all of his innates and facets are named to have the "OD" acronym as well.
  • Additionally, his innate ability, Ominous Discernment, displays a different name in the hero loadout. Possible names include:
    • Obstreperous Dissimilator
    • Obnoxious Determinator
    • Obsequious Deliberator
    • Ornery Deconstructor
    • Obnubilated Delineator
    • Omniscient Desiderator
    • Funnily, the default name Ominous Discernment is not within the list and therefore never appears in the loadout.

• Warcraft 3 similarities:
  • Outworld Destroyer uses the model of the Destroyers, a ranged Undead unit trapped within Obsidian Statues.
  • In DotA, his title is Obsidian Destroyer, combining the names of the Destroyer and the Obsidian Statue.
