So I finally have an idea for a villain I like, Red Queen the Irish witch, and I came up with this odd sort of Blast power I wanted to run by folks. The idea came to me as a visual: doing a hit with a silenced pistol, minus the actual pistol. RQ would get behind someone, touch the back of their head with her finger, and then Paff!, they're dead. I was thinking of doing this with a Penetrating Blast with one level of Subtle but Range dropped down to Touch, so there would still be a flash, a bit of noise and a lingering stench of brimstone, and of course a corpse.
I know a Touch-based Blast is kind of weird, but I love this concept so much - is there a better way to do this?
