Was having trouble finding a WA to help me track stacks and duration left on JoL debuff so I made this pretty simple string that shows every Judgment debuff you have out (growing from left to right), and also plays a sound and has a flashing icon when Judgment is off cooldown so you know to recast it again.
Planning on asking a friend soon to help me with a custom trigger on the "off cooldown" icon to only trigger if no enemies in range have the debuff (since you don't need to re-apply otherwise), but if you're savvy and would like to help, go ahead!
