I'm confused about the rules of Requiem 2e with respect to Style Merits.
As far as I can tell, Requiem 2e itself doesn't define the Style keyword, but there's this in the God-Machine Rules Update, pg. 158:
Merits marked as Style Merits allow access to specialized maneuvers. Each maneuver is a prerequisite for the next in its sequence. So if a Style Merit has a three-dot maneuver and a four-dot maneuver, you must purchase the three-dot version before accessing the four-dot.
The presentation seems to indicate this is a special rule for Style Merits, but I'm not clear on exactly what the difference is.
If I want to learn the first three moves of Kindred Dueling, do I need to pay…
A. 1 XP for Dueling •, 2 XP for Dueling ••, 3 XP for Dueling •••, all written as separate merits on my sheet, for a total cost of 6 XP?
B. 1 XP for Dueling •, 1 XP to upgrade it to Dueling ••, 1 XP to upgrade it to Dueling •••, for a total cost of 3 XP?
