Temerity is a Unique Pants. It can be used by any class.
Temerity Pants are a powerful defensive item that has received significant buffs in the latest patch, making them a standout choice for tanky builds in Diablo 4. What makes them exceptional is their ability to boost your maximum life, which enhances their unique effect: a barrier that scales with your maximum life, offering substantial protection.
Additionally, these pants provide a potent combination of damage reduction while healthy, increased healing received, and a chance to heal on lucky hits, all of which synergize to keep you resilient in combat. When paired with the Starlight aspect, they even enable mana regeneration through healing, making them versatile for various builds. These attributes make Temerity a must-consider item for players seeking to maximize survivability and sustain in their gameplay.
