Intelligence

Intelligence (represented by the icon in-game) is an Attribute that grants Mana and Mana regeneration. For each point of Intelligence a Hero has, their maximum Mana increases by 13, and their Mana regeneration increases by 0.04 Mana per second. Intelligence Heroes gain additional attack damage for every point of Intelligence they have.

Intelligence Heroes
Intelligence Heroes have larger Mana pools and can regenerate Mana faster than other Heroes, which means they tend to focus on using their Abilities to deal damage. They often fit into support and ganker roles. Intelligence Heroes are almost all Ranged Heroes, except for Dark Seer and Ogre Magi. Because their Abilities do not scale with their levels, Intelligence Heroes often fall off during the late game. At the moment, there are 37 Intelligence Heroes implemented in Defense of the Ancients, and 29 implemented in Dota 2.

Below is a table of all Heroes with Intelligence as their primary attribute.
