Dota 2/Harbringer the Outworld Devourer

Outworld Destroyer is a ranged intelligence hero who is arguably the only intelligence hero that fits the role of a hard carry. He is very reliant on his intelligence stat, from enhancing his spells to weakening enemy casters. He can use Astral Imprisonment to steal intelligence from his enemies. His Arcane Orb and Sanity's Eclipse both become more powerful with more intelligence. He can also buff up his team's spellcasters with his Essence Aura, ensuring that they are almost never starved for mana.
