Can you 100% complete Dark Souls 3 using only melee weapon?

As far as I remember, one can 100% complete dark souls 1 using only melee weapon, that means to reach and kill every boss and find every item without using spells, bows, throwing knives and stuff like it.

Is the same true for Dark Souls 3?

I'm asking because I am facing the tree in Undead Setlement, which has a treasure hanging on its branches, that treasure looks unreachable without range. Please don't spoil that specific case, I just want to know the general answer to the question whether I can constrain myself by "melee only weapons".

Solution 1:

No.

For example, the Red and White Shield is only reachable with ranged weapon.
