Incantation of Lightning - why R:Voice?

Yes, that's a touch-range incantation of lightning. Like a touch-range BoaF.
I'm 100% with callen on this one: Making lightning appear at your fingertips (touch range) or on a distant target (voice) is exactly as unnatural. In one case, you'll fry someone you touch, in the other, someone further away.

We disagree on this. It's one of those mileage issues. If your troupe agrees, fine, go with it, but, clearly, not everyone will.

How many, since you warrant creating a lightning bold in a cave or building to be only worthy of a +1 magnitude? I doubt very much Callen's lighting bolt, passing through a window (or even a dozen), would be worth more than this (and it certainly should be worth less).
