NIce there are still this kind of quests
In previous games you had to check every quest item if it`s usable to see what it might give you before finishing quest :
KB-tL - potion for alchemist , Norics bag, ...
KB-Ap - treasure map on Scarlet wind, amulet of illumination, Shetera dragon blood sword and many others.
So players keep track on what each quests asks you to do, before finishing it
