Shows a Progress bar of how many herbs you have to pick up to a certain ammount
Once that threshold is reached the Progressbar disappears.
To toggle the visibility of the Aura, you can use this Macro;
/run toggle_single = not toggle_single
and bind it to any key.
To change the minimum and maximium ammount of herbs you want to show,
you have to go into the settings and change the Custom trigger 2 to whatever number you want, Just make sure you change all three strings within trigger 2.
