Intelligence

Intelligence is the attribute that grants mana, mana regen amplification and spell damage amplification to every hero. Intelligence heroes gain 25% more than other heroes, and also gain attack damage.

Bonuses

Strength and agility heroes gain the following bonuses for each point of intelligence:

• 12 Mana
• 1.8% Mana regen amplification
• 0.07% Spell damage amplification

Intelligence heroes gain the following bonuses for each point of intelligence:

• 1 Attack damage
• 15 Mana
• 2.25% Mana regen amplification
• 0.088% Spell damage amplification

The mana bonus is only applied to the maximum mana pool. The hero's current mana is not increased, but keeps the current mana percentage. To gain 1% spell damage amplification, 15 intelligence points are required.

Intelligence heroes

Intelligence heroes tend to have a greater number of active abilities compared to other heroes; all intelligence heroes have at least three active abilities, with a large number of them having all four of their abilities being actives, and some even having 5 or more. 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 a few exceptions, most intelligence heroes are ranged. Most intelligence heroes rely on their spells for damage, but in most cases, these have static damage values only increased by spell damage amplification or damage manipulation. They do not scale well into the late game, so that most intelligence heroes peak during the early to mid game, where their spells deal the most damage in relation to enemy health pools and resistance, and then start to fall off in the late game. Because of this, they often fit into support and ganker roles. There are exceptions to this though, some intelligence heroes have scaling abilities which make them excellent in the late game.

There are 41 intelligence heroes 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 increases for each level of the hero.
