Endurant Faith is a Unique Gloves. It can be used by any class.
Endurant Faith is a new unique item in Diablo IV's Season 5, designed to prevent one-shot deaths by converting large damage hits into damage-over-time effects. Drawing inspiration from a similar mechanic in Diablo II, this item is ideal for characters with moderate to low health pools who are vulnerable to sudden, massive damage spikes.
In addition to this primary effect, Endurant Faith offers bonuses to all stats, maximum life, and lucky hit chance, while also increasing healing received. It’s particularly useful for players looking to mitigate high-damage scenarios and enhance their survivability in challenging content.
Effect
When you would be damaged for at least 40% of your Maximum Life at once, it is instead distributed over the next 3 seconds and reduced by [10 - 30]%.
