Jade Serpent Statue Tracker. Visible only in combat (but target tracking works out of combat too), shows a desaturated, glowing icon when no statue is down, colored & glowing when the statue is down, but isn't chanelling. Also shows the target above the icon.
It is best used with the rest of my UI collection, as it is strongly tied to it: https://wago.io/oAL0YDLyI
