先兆者，殁境神蚀者，是一个远程智力英雄，可以在游戏中充当核心, though unlike traditional carries, he excels against high-armor targets whilst being crippled by spell immunity. With 奥术天球, 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 enjoys more-or-less unlimited mana because of his 衡势, which can be activated to replenish his mana from the damage dealt by his spells. With 星体禁锢, Harbinger can render himself or an ally invulnerable for a short period of time, or disable the target enemy. His ultimate, 神智之蚀, can instantly deal colossal area-of-effect damage against his enemies based on how much greater his intelligence is than theirs.

|玩法风格：||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 阿哈利姆神杖. The reason for this is because in Dota 1 early development Aghanim's Scepter was made using 神秘法杖 and a 镇魂石 giving 500 mana and 30 int, which helped Outworld Devourer tremendously.
