I know that in the beginning of this quest you need to get a shadowed
scythe.Once you turn that in you get a note asking for the additional 3
needed items.My question is, if you already know the other 3 items needed, do
you even have to do the shadowed scythe part?Also, can someone please give me
the approximate level of the goblin in OOT who drops the shadowed knife?

Thanks in advance!
