I think this is a quick question, but I can't find anything on line on this specific question.
I Chewbacca happens to get a surge on the red dice roll when doing slam can he spend it. I think slam only does the actual damage on the dice and ignores surges, but with the upcoming Chewbacca fix I wanted to get a definitive answer in the event it comes up.
I am figuring the fact it isn't an "attack" makes it more like "Grenadier"
