Class resources in Diablo 4 (D4) are mechanics unique to each class in order to cast skills and abilities. See how each class generates their own resource, as well as their properties!
List of Contents

Each class has a unique resource with its own mechanics. Class resources govern the usage of skills and abilities. Each class also has their own tools of generating resources, which is slightly indicative of their play style.

The maximum amount of class resources can be increased by wearing certain equipment and by investing in Skill Passives such as Tempered Fury for Barbarians, and the Sorcerer's Devastation.
