After a closer look, I think there might also be a different mechanic for the Lightning Bolt spell amp.
I think this one says "Combat Spell. Damage of 6P/AA. Defense = S + W" -- it's a little hard to read, that might still be an 8P..
Compare that to Coydog's Lightning Bolt amp from the prototype: "Combat Spell. Damage of 8P/-A, may reroll one failed Sorcery die, defense S + W"
Not sure if this means they dropped the re-roll part of the amp?
Also, it looks like there are 10 spots for cues... I know that some comments from people who have played the Cue system have expressed concern about the small number of cues in the prototype as compared to Cosmic Patrol, so maybe this increase will help address that.
