Fury is the resource used by the Barbarian.
The Barbarian generates Fury when in combat and it slowly depletes over time while out of combat.
Skills can consume Fury quickly but all Basic Barbarian skills such as Flay, Bash, Frenzy, and Lunging Strike generate Fury whilst costing none. However, other skill trees have some skills that can either directly gain Fury or at least boost its gain.
