[Fractal] Uncategorized [Boss] Raving Asura [Agony attack description] 
The asura will shoot a chain of arcing lighting balls at random players. Each of these balls inflicts agony so you will need to dodge towards the boss to avoid them all. This agony attack can also be reflected or have someone kite the asura around the pillars while the rest of the group kill the golems.
