Strength

Strength (represented by the icon in-game) is the attribute that grants health and health regeneration. Every point of strength a hero has increases their maximum hit points by 19, and their health regeneration increases by 0.03 HP per second, meaning Heroes gain 1 health per second for every 33 points of Strength. For Strength Heroes, every point of Strength increases their damage by 1.

Strength Heroes
Strength heroes tend to have more health and health regeneration than heroes of other classes, making them more resilient to both physical attacks and spells. Strength heroes have the greatest variety in their roles, including that of carry, ganker, and support, but almost all of them have some form of strong initiation and are supposed to act as tanks to some degree. In addition, heroes with a large amount of strength may greatly increase the damage needed to bring a team down. With the exception of Huskar, Io, Phoenix and Dragon Knight in his Elder Dragon Form, all strength heroes are melee. Whilst Intelligence heroes typically sport a strong early game, and Agility heroes excel in the late game, Strength heroes are often able to strike a balance between the two and remain relevant at all points of the game. At the moment, there are 37 Strength Heroes implemented in Defense of the Ancients, and 36 implemented in Dota 2.

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