Attribute Bonus
Also known as stats, was a passive ability possessed by every hero. Each additional level of Attribute Bonus increases all attributes—strength, agility, and intelligence—by 2. Attribute Bonus is distinct from the automatic attribute increases gained by every hero at every level. Just like regular abilities, heroes can place a new ability point in Attribute Bonus at every odd level. Attribute Bonus can be leveled a maximum of 10 times, at levels 1 / 3 / 5 / 7 / 9 / 11 / 13 / 15 / 17 / 19.

Attribute Bonus is a convenient way to compensate for a hero's early-game weakness without filling inventory space. For example, Wraith King and Sven have very low intelligence, so they often take a few early levels of Attribute Bonus to improve their mana pool.

Adding one level to Attribute Bonus is functionally equivalent to having a Circlet or two Iron Branches.
