Arcane Orb
 Gives the Destroyer extra power to damage his enemies based on his remaining mana pool.
Notes • Damage type: pure• The damage is calculated after the mana cost is spent.• Does not stack with orb effects and buff placers.
Astral Imprisonment
 Teleports a target allied or enemy hero into an astral prison. The hero remains separated from the real world for the duration of the spell. If cast on an enemy, Harbinger steals intelligence from the target.
Notes • When cast on an ally, no intelligence is stolen.• Imprisoned units are hidden and invulnerable.• Imprisoned units can still be hit by Sanity's Eclipse.• The -disablehelp command will prevent an allied Harbinger from casting this spell on you.
Essence Aura
 Whenever a nearby allied hero casts a spell, it has a chance to restore a portion of its mana pool.
Notes • Arcane Orb has the regular 10%/20%/30%/40% chance for mana restoration, whether autocast or cast manually.• Several skills with no cooldown (such as the Storm Spirit's Ball Lightning) and toggled spells (such as the Witch Doctor's Voodoo Restoration) cannot trigger Essence Aura.

Sanity's Eclipse
 The Obsidian Destroyer unleashes his full potential; his mind unleashes a psionic storm able to penetrate lesser minds with terminal force, dealing massive damage to them. More crafty minds are able to resist most of the damage, but they expend most of their energies to do so, losing a lot of their mana.
Notes • Damage type: magical• If an enemy hero has an intelligence difference lower than 10/30/50 (at level 1/2/3), but greater than 0, he will lose 75% of his current mana.• * with Aghanim's scepter• It will hit units under the effect of Astral Imprisonment.
Hero Introduction
Among the small number of intelligence heroes who focus on getting a lot of powerful items late in the game, the Obsidian Destroyer relies on building up as much intelligence and mana as he possibly can. His deadly Arcane Orb enhances his attacks with large amounts of unresistable pure damage, and if his mana pool gets high enough the Obsidian Destroyer is capable of killing fragile enemies with only a few Arcane Orb attacks. Astral Prison is a useful ability, which can put a powerful enemy hero out of the fight or save an ally from death. In addition, it drains intelligence when cast on an enemy hero, and by repeatedly using this ability the Obsidian Destroyer can quickly reduce the enemies' mana pool, making it difficult for them to cast many spells. To keep both his own and his allies' mana pools full, the Obsidian Destroyer has a passive skill called Essence Aura. In addition to boosting the Destroyer's own mana pool, this aura gives any allied unit under its effect a chance to instantly regain a portion of their total mana pool every time they cast a spell. Essence Aura fuels Arcane Orb, giving the Destroyer potent damage with little risk of running dry. Although Arcane Orb and Astral Prison make the Destroyer deadly in small engagements, his powerful Sanity's Eclipse spell can turn the tide of large battles. An Obsidian Destroyer with a lot of intelligence items can kill or badly wound several enemy heroes at once with this spell. Few heroes are capable of putting out as much damage as a pumped up Obsidian Destroyer.
Background story
An obsidian construct brought to life through the ill conceived necromancy of the Lich King, Harbinger craves magic to make up for the emptiness brought on by the incomplete nature of its summoning. Ironically however, to devour the magic that it so desires, Harbinger must tap into his own pool of mana time and time again, expending to the point where it ends up with even less than it began with. Yet despite this, the Obsidian Destroyer is a proud servant of the Undead Scourge, and takes great pleasure in annihilating the foolish Sentinels it encounters through psionic exploitation.
