All off you Shattered sun offensive pepole are surely doing the dead scar bombing quest. Uintil lately i found out that you could use a little smart exploit here. For example. Bind your arcane bomb to action button "4" now while you fly try rapidly press Bomb utton while rapidly pressing at the spot you target. You will soon see that you have fired 2 bombs with only one cooldown on bomb. YOu should really try thisMy personal record is 5 bombs same time.
