I am looking for a very specific progress bar which I belive comes from some PVE encounter or quest related to Isle of Thunder(almost 100% it was in MOP somewhere)
Color is greenish-blue or something similar to what Yu'lon color is and with vein like patttern inside which fills up.
After several hours of googling only thing I was able to find was Lei Shen bar which is not what I am looking for.
Do you guys have any tips where I should look for it?
