Here is the scenario: player A attempts to shoot a bounty hunter; he misses but rolls three advantage. How many boost die can player A grant player B? Just one, or three?
I have always been under the impression that the correct answer is "one" - my primary rationale is because the advantage usage to regain strain explicitly states it can be used multiple times, whereas the usage to grant a boost die to an ally does not. …but some recent posts have made me wonder if my interpretation is correct.
I know there are at least a couple of you who would say the right answer is "three" and that you can stack up blue die (and by the same rule, black die as well by spending multiple advantage)… so, which is the right way to interpret these rules, and why?
(also, let's consider that this should consistently apply).
