Intelligence

Intelligence is the attribute that grants mana, mana regeneration and spell damage amplification. For each point of intelligence a hero gets:

Additionally, intelligence heroes also get 1 attack damage per intelligence point.

To gain 1 mana regeneration, 25 intelligence points are required, and to gain 1% spell damage, 14 intelligence points are required. The mana increase only applies to the maximum mana, the hero's current mana is not increased by 11. The current mana percentage stays unchanged upon gaining intelligence.

Intelligence heroes[edit]

Intelligence heroes tend to have a greater number of active abilities compared to heroes of other classes; all Intelligence heroes have at least three active abilities, with a large number of them having all four of their abilities being actives. Their larger mana pools and higher mana regen rates go a long way to help them use these abilities frequently. As a whole, Intelligence heroes have by far the greatest number of disabling capabilities, making them essential in most lineups. The items they build also tend to be highly caster based, since those items primarily provide Intelligence. With the exceptions of Dark Seer and Ogre Magi, all Intelligence heroes are ranged. Because most Intelligence heroes have abilities such as static damage nukes that scale poorly, they tend to have a strong early game, when enemies' health pools are low, but a much weaker late game, when enemies have high health and strong defensive items. Because of this, they often fit into support and ganker roles.

At the moment, there are 40 Intelligence Heroes implemented in Dota 2.

Below is a table of all heroes with intelligence as their primary attribute. The growth columns indicate by how much the base values will increase for each level of the hero.
