Most-bought items for Outworld Destroyer in OpenDota’s sample of parsed public matches (1,813 purchases counted). Bars compare each item with the most-bought one in its phase. The percentage is the win rate in games where Outworld Destroyer bought the item by minute 30 (green or red when it is clearly above or below Outworld Destroyer’s average). Teams that are ahead buy items sooner, so a high number shows the item goes with winning games, not that it causes the win. Items with fewer than 100 games show no percentage. Cheap components are hidden from the mid and late game.

Final items compared within the same purchase window (at least 60 games each), so they are not simply ranked by how late or expensive they are. Still a correlation: a team that is far ahead can buy anything sooner.

Adds extra pure damage to Outworld Destroyer's attacks, based on his remaining mana pool.

Steals a percentage of the target's max mana and places them into an astral prison. The hidden unit is invulnerable and disabled. When the astral prison implodes, it deals damage to the target.
Aghanim’s ShardAstral Imprisonment now deals damage in an area. Also allows allies to move at 70% movement speed during Astral Imprisonment (they are visible, but untargettable and can't perform any other actions).

Increases Outworld Destroyer's maximum mana. When cast, protects Outworld Destroyer with an all damage barrier equal to a flat amount and a percentage of his maximum mana.
Aghanim’s ScepterIncreases max mana to barrier. Damage that would bring Outworld Destroyer below 20% health is prevented. When that happens, Outworld Destroyer receives a strong dispel and gains an undispellable instance of Objurgation. This effect cannot occur more than once every 80 seconds.

Passively grants a chance to restore a percentage of your max mana each time you cast an ability. Restores less mana from spells that modify attacks.

Unleashes a psychic blast that deals damage to enemies based on the difference between your max mana and the target's max mana. Sanity's Eclipse can hit units trapped by Astral Imprisonment.

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.
