What Does Fortify Do?

Reduces Damage Taken

Fortify is a positive status effect that grants 10% damage reduction. It has a separate and maximum value, similar to Life and class resources. Fortify value cannot exceed the amount of maximum Life, and Fortify depletes when out of combat.

How Fortify Works

# How Fortify Works
1
Diablo 4 - Inactive Fortify
When gaining Fortify from Skills and other sources, it appears as a separate layer on the Life globe, and has a different shade of red.
If current Life exceeds Fortify value, Fortify is not yet active and there is no damage reduction for incoming attacks.
2
Diablo 4 - Active Fortify
When current Life is equal or below Fortify value, Fortify activates and the damage reduction kicks in. This is indicated by a ring around the Life globe. Losing Fortified Life will also cause you to lose Fortify and Life by the same amount.

How to Get Fortify

Upgrade Your Skills or Equip Items with Fortify

Barbarian Skill with Fortify - Diablo 4

Depending on the class you are playing, some Skills have an upgrade path that grants you Fortify. Some skills or passives can also grant buffs to Fortify and its effects, but this does not necessarily grant Fortify itself unless explicitly stated.

Alternatively, you can also equip items with aspects or stats that grant you Fortify too.

Does Fortify Count as a Barrier?

No, Fortify and Barriers are Different

Diablo 4 - Fortify and Barriers are Different

Fortify and Barriers are completely different mechanics, and passives that improve Barriers do not affect Fortify. Barriers absorb incoming damage, while Fortify reduces incoming damage.
