Once you hit max level, you no longer are able to keep track of XP. This addon changes that and would tell you (approximately) where you would be if the max level was higher. Levels gained are called "Paragon" levels showing your dedication to the grind. Upon installing, you will see an XP bar very similar to that of the standard Blizzard bar. You can move this bar by right-clicking and dragging. This bar may not leave the screen. XP may be earned only by killing enemies. Raid trash and bosses will give XP. Enemies deemed "trivial" by the game do not count towards XP.
