Overcast

Effect: Exhaustion is technically not a condition, as it is not targeted by skills that effect conditions! It is currently only self-imposed by certain elementalist skills. The effect of exhaustion is triggered when you begin casting the skill, and will stay even if the skill gets interrupted. While exhausted, the elementalist's maximum energy supply is reduced by 10. The right end of the energy bar is greyed out. This reduction will be restored at a rate of 1 point every 3 seconds.

Exhaustion does stack; if you cast several skills that cause exhaustion in succession, your maximum energy supply will become severely reduced. Exhaustion can go above your energy max so that your bar is more than 100% greyed out?
