Bloodborne Key Items Locations Guide - Keys, How to Use

Key Items in Bloodborne are quite similar to the ones found in the Souls series. They usually come in the form of unique items that serve a purpose that deviates from the conventional function of consumables.

Some of them are literally keys, while others are odd pieces of equipment that you wouldn’t really understand the use of through their description.
