Outworld Destroyer

Outworld Destroyer is a ranged Intelligence-based Hard Carry, relying on stacking Intelligence to crush his insignificant foes. Thus, Destroyer focuses on buying Intelligence items that will increase his power for him to unleash his full potential as a late game Hard Carry. This dark and mystical being will destroy fools who dare to combat him, throwing Mana-enhanced attacks while regaining his own energy again and again. He is also capable of sending them to an astral prison, or vanquishing them with a mind-breaking storm. Harbinger's very presence signifies impending danger and great cataclysm.

Tips

 * Astral Imprisonment is a good harassment spell early game since you can steal intelligence from enemy heroes. This can be used effectively against strength based heroes since their intelligence is fairly low, lowering their maximum mana points or intelligence based heroes to steal damage from them while adding to your own. Additionally, the intelligence steal stacks if you cast it multiple times on the same enemy. Make your foes so stupid they can't even cast a spell!
 * Another way to harass with Astral Imprisonment is whenever your lane creep is about to die and your enemy heroes want to kill it, banish him then deny that creep to completely remove the experience that hero should have gained regardless being able to kill that creep or not.
 * Purchasing items that increase your maximum mana or Intelligence will greatly increase the damage of your Arcane Orb.
 * You should always use Sanity's Eclipse at the start of each combat since the mana burn (75%) is significance enough to shut down any nukers or supporters like most Intelligence heroes after they use 1-2 of their spells, while dealing some damage to soften the Strength and Agility heroes.
 * Unlike most auto-cast spells, Arcane Orb can be targeted by Pugna's Nether Ward. Be careful about using Arcane Orb when Pugna is around!

Trivia

 * Outworld Destroyer's original title was Obsidian Destroyer, a name that is similar to two units from Blizzard's Warcraft 3. Those two units are Obsidian Statue and Destroyer.
