elememtalist energy

What is the deal with my elementalist. I have like a double energy bar, one recharges normally, and the other goes real slow. I can't be the only one with this, and it was never there b4. Can anyone tell me what happened?

if it's grey, this is because of a condition named exhaustion. It's caused by spell you cast.

Exhaustion make you loose 10 max enegy for a short time. i don't remember how fast you regain it but i think it's 1 each 3 second. So don't bring too much spells that cause exhaustion and don't cast them too much.

come to think about it, that is exactly what it is. Thank you ever so much, now i understand
