In Dota 2, understanding the three hero attributes—Strength, Agility, and Intelligence—is crucial for mastering the game, as each attribute influences gameplay style, hero roles, and overall effectiveness on the battlefield. Let’s delve deeper into how these attributes affect heroes and their strategic implications.

1. Strength Heroes
– Stat Bonuses: Strength heroes gain +22 health and +0.1 health regeneration per point in Strength. Additionally, each point of Strength increases their main attack damage by 1.
– Role and Gameplay: These heroes are naturally tankier, making them ideal for absorbing damage during engagements. Commonly fulfilling roles such as initiators or tanks, they remain relevant throughout the game due to their robust health pool and regeneration capabilities. Examples include heroes like Earthshaker or Centaur, who can engage fights effectively while soaking up damage for their team.

2. Agility Heroes
– Stat Bonuses: Agility grants +0.167 armor and +1 attack speed per point, along with the damage increase of +1 per point of Agility.
– Role and Gameplay: Typically classified as carries, Agility heroes excel at dealing physical damage and are characterized by their high attack speed and survivability. They thrive in the late game, where their damage output can be formidable. Heroes like Anti-Mage and Phantom Assassin exemplify this role, scaling their effectiveness as they gather items and farm effectively.

3. Intelligence Heroes
– Stat Bonuses: Intelligence heroes receive a boost to their maximum mana, enhance their mana regeneration, and improve their spellcasting abilities due to higher spell damage and reduced cooldowns.
– Role and Gameplay: Often serving as spellcasters or supports, these heroes leverage their abilities to control the battlefield and provide utility to their team. Heroes like Invoker and Crystal Maiden showcase this attribute, relying on their spells for damage output and crowd control rather than physical attacks.

4. Universal Heroes
– Overview: A newer category introduced into the game, Universal heroes benefit from all three attributes for their attack damage, allowing for a flexible and multifaceted gameplay style. This complexity can make them appealing but also challenging to master, as they can adapt to various situations but may require careful itemization and strategy to optimize their performance. Examples include heroes like Marci and Dawnbreaker.
