Re: "Uh ... you can *do* that?"
This is something that I forgot I could do, but in a different way.
My very first Champions game, I'm running Osprey, a metamorph who could turn into a winged form with claws and a sonic scream. The GM has me going up against an air elementalist, who's got a double knockback wind blast.
I end up taking out the elementalist and afterwards, the GM and other players complimented me on the fact that as a newbie, I had the good sense to actually pick up the tactic of not flying around the air elementalist.
I blink.
I forgot my character could fly.
