Derives heavily from https://wago.io/bc2vW-miz with some minor modifications.
This WA helps remind players that they have no Essence Sap stacks and are available to soak. As their stacks rise, a circular debuff timer appears and changes from green to yellow, then red at 10 stacks.
Plays a "soak" sound when your stacks clear, and plays a "high stacks" sound when stacks get to 10. You'll need https://wow.curseforge.com/projects/sharedmedia_causese to hear these.
