Let's say I'm farming an overland set. And let's say, in that particular zone, I have the following stickerbook record:
Overland Set 1: Missing one weapon only, and everything else is already collected.
Overland Set 2: Missing all pieces.
Overland Set 3: Missing all pieces.
If I kill a world boss, what are my chances of getting the one weapon I'm missing from Overland Set 1?
Are they 1/3? As in, does the game first pick one of the three sets at random, (regardless of how many pieces you're missing,) and then assign you one of missing pieces from that particular set?
Or are they much, much lower than that? As in, the game doesn't differentiate between the three sets, and instead, looks at all the pieces you're missing from all three sets, and assigns you one of the missing pieces at random?
Does anyone know?
