Who Can Get Fortify in Diablo 4?

The Fortify Ability is available to the following classes in Diablo 4:

  • Barbarian
  • Druid
  • Necromancer

The Fortify Ability offers Damage Reduction to your character. The default damage reduction is 10% but increases through specific items, Passives, Paragon slots, Legendary Aspects, and other Abilities.

You can find out which parts of the skill tree can further extend the powers of your Fortify by using the “Search” function in a Diablo 4 Skill Tree Build Calculator, which you can find in our article below:

How Does Fortify Work in Diablo 4?

Let me clarify how Fortify functions. To put it simply, your “Health” globe is represented by red liquid, symbolizing blood. If you possess “Fortify”, you will notice two shades of red within the globe – a lighter and a darker one. The darker shade denotes your “Fortified HP”, which acts as a “Last Stand” mechanism when your HP falls below the threshold. At this point, the damage reduction commences. Here’s a small example:

  • You have 100 Max HP
  • Your Fortified HP Max is 20
  • You take five instances of 20 damage.

Based on your current HP of 80, the initial four damages will affect you normally. However, for the remaining 20 HP, your Fortify will activate with a default mitigation of 10%, resulting in you having 2 HP left.

Once your HP drops below the maximum fortified HP threshold, you will be fortified and a metal shield will surround your globe. It’s important to keep in mind that if you’re out of combat for five seconds, your Fortify will start decaying.

Also, more Fortify means more Overpower damage!
