I made this video to show where to find two of the hidden bosses Celestial Emissary & Ebrietas, Daughter of the Cosmos are in Bloodborne. If you watched my walkthrough, I missed these guys so as an amendment, here they are. Since I had no idea where these guys where, I thought I’d share the wealth.
It all starts with an item I couldn't figure out how to get. With it, everything clicks and you can finally open that closed door in the Cathedral Ward that has been bugging you this entire time. Here, you’ll find both of these bosses, one after another. First, the Celestial Emissary is having fun playing in a garden of other like blobby pals and then Ebrietas, Daughter of the Cosmos is behind a destroyable wall in the properly named Alter of Despair.
Happy hunting!
