I've always seen it as a Plot Coupon
is a McGuffin
you cash in to advance the plot. It's something you actually need to obtain to further the plot. A McGuffin
can be just the goal no one ever reaches.
You don't have to give the Plot Coupon
up for it to count as one, but it has a specific use in the plot. If it's a Plot Coupon That Does Something
it has a practical use aside
from that specific purpose. Which technically makes it an combination of a Plot Coupon
and a piece of equipment or a functional item.
So it can't just be one of the many items in Zelda
, as they're tools you use exactly as they're intended (Sequence Breaking
aside), even if you technically use them to get past specific obstacles similar to a Plot Coupon
. For instance, the Master Sword in the Zelda
games usually has an impact on the plot, aside from just being a better sword than the previous. Maybe not the best example, as it's also an example of Sword of Plot Advancement
, which is a subtrope to Plot Coupon That Does Something
