A circular tracker for Brewmaster's Ironskin Brew.
The outer ring tracks the cooldown of available charges and supports both LB and non-LB talent settings. The last segment of the ring turns red when Keg Smash would cap your brews (this is a sign that you should use your brews!)
The inner ring tracks the current duration of ISB and changes color to represent the remaining duration.
The inner ring begins flashing red when your remaining ISB duration drops below 3s.
