I'm curious, on step 3 under making rolls you say that "If the character's skills apply, upgrade" - it's not clear if you mean the active PC making the check or the character helping. Then on page 7 when talking about Characters, you say that characters get +1 ability die "when making roll where their skills are helpful" which seems to contradict with the upgrade from earlier.
Have you given any thought to this since the alpha? I'd love to know your intention and see where you think the upgrade comes into the picture!
