Strength

Strength (represented by the icon in-game) is the attribute that grants health and health regeneration. For each point of strength a hero has, their maximum hit points increases by 19, and their health regeneration increases by 0.03 HP per second.

Strength heroes gain attack damage based upon their strength.

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, Dragon Knight in his Elder Dragon Form, and Phoenix (who has not yet been implemented into Dota 2), nearly all strength heroes are melee.

At the moment, there are 39 Strength Heroes implemented in Defense of the Ancients, and 34 implemented in Dota 2.

Below is a table of all heroes with strength as their primary attribute.
