Understanding the Mechanics of Armor in Dota 2

When it comes to mastering the intricacies of Dota 2, understanding the various mechanics that govern the game is key. One such mechanic that plays a crucial role in battles is armor. In this blog post, we will delve into the world of armor in Dota 2 and explore how it works to protect your heroes from harm.

Key Takeaways:

  • Armor reduces both physical damage and the chance of being critically hit.
  • Armor in Dota 2 follows a diminishing returns formula.

How Does Armor Impact Physical Damage?

Armor in Dota 2 serves as a shield for your heroes, mitigating physical damage inflicted by enemy attacks. The higher the armor value, the more damage reduction your hero will have. For each point of armor, your hero’s effective health against physical damage is increased by 6%. This means that heroes with higher armor will be able to withstand more attacks before succumbing to their injuries.

It’s important to note that armor does not directly reduce the damage taken, but rather decreases the damage multiplier applied to incoming physical damage. This is based on a simple formula:

Damage Multiplier = 1 – (0.06 × Armor ÷ (1 + 0.06 × |Armor|))

Let’s break down the formula further to understand how armor reduction is calculated:

  1. For positive armor values: Each point of armor provides a percentage decrease in damage taken.
  2. For negative armor values: Each point of armor provides a percentage increase in damage taken.

Therefore, the more negative your armor rating, the more susceptible your hero becomes to physical damage.

Does Armor Affect Critical Hits?

In addition to reducing physical damage, armor also affects the chance of being critically hit. Each point of armor increases the effective hit points of a hero against critical strikes, making them more resistant to these powerful blows.

However, it’s important to note that the reduction in critical hit chance provided by armor is not as significant as the reduction in physical damage. This means that while armor can help mitigate the damage from critical hits, it is not a foolproof defense against them.

Understanding Diminishing Returns

Armor in Dota 2 follows a diminishing returns formula. This means that the more armor you have, the less effective each additional point of armor becomes. In other words, the higher your armor value, the smaller the damage reduction gained from each additional point of armor. This mechanic encourages players to find a balance between building armor and other defensive or offensive items.


Armor is a vital aspect of Dota 2 that can make a significant difference during battles. By understanding how it works and utilizing it effectively, you can increase your hero’s survivability and turn the tide of the game in your favor. Remember, while armor provides protection against physical damage and critical hits, it’s important to also consider other factors such as magic damage and crowd control effects when strategizing your hero’s build.

So, gear up with the knowledge of armor mechanics and take your Dota 2 skills to the next level!
