The book is vague, if silent, about how to spend advantages and if they can do so for the same thing more than once. What I mean is, if a player has 5 advantages, should they be able to give the next player 5 boost dice (1 boost per advantage)?
I've been playing it as a "yes they can" but it feels a little powerful. But, then again, that's a ton of advantage. So it also makes contextual sense.
Thoughts?
