Shows a progress bar for how long each Rune of Power will last once it has been cast by Runemaster Molgeim.
This weakaura assumes that each Rune of Power lasts ~36.8s once it is cast. Sometimes the Rune of Power will last very slightly less or more, blame Blizzard.
This weakaura will also show a red glow around the progress bar when there is <5s left. You can turn this off in the conditions tab if you don't want this.
