I have noted that sometimes I will sneek into a situation and go to two handed fire either chain lighten, or one or more of the other bolts. But a number of times I have gone to fire, and I get a small "POOF" and nothing really happens ? I had it happen once through an entire fight scene. I finally drew my sword and strated fighting. But this always gives me away, and does zero damage to the target. Any one ealse encounter the shoot blank scenero ??
I assume you charged it fully. Never had that happen to me. Although, I have had the animations on the casting hand fail to display properly, but he spell fires off to the enemy as normal.
My raise dead spells only work intermittently and no it's not because I'm trying to raise something too powerful. There the only spells Inhave trouble with.
