Adrenaline

Adrenaline is a resource unique to the warrior profession. Its primary use is to fuel burst skills, which become more powerful with each full stage of adrenaline.

There are three stages of adrenaline, and each attack made by the warrior in combat grants one "strike" of adrenaline, equal to approximately 3.3% of the completely full adrenaline capacity. It takes 10 strikes of adrenaline to fill each of the 3 stages.

Using a burst attack expends all adrenaline, and the effect and power of a burst skill depends on how many complete stages of adrenaline were built. Adrenaline depletes over time after a while when the warrior is not engaged in combat, but only after being out of combat for 30 seconds or so. Burst skills can still be activated out of combat provided that the warrior has enough adrenaline to do so. Adrenaline will not be expended if the burst skill does not connect with any enemy target.
