So how do the vessel attacks work? On page 39 there is a list of individual attack bonuses for each npc, but the ritual writeup on page 74 states their attack bonus is based on the degree of the ritual's success. I can find nowhere in the pdf where both of these attack rolls are mentioned in the same paragraph, which leads me to think they're from different drafts in the process of writing chapter 7.
Are these bonuses meant to be added together?
