Ebrietas, Daughter of the Cosmos, is an optional boss fight you can find in the Upper Cathedral Ward area in Bloodborne. It's a really, really difficult fight — her attacks hit hard, she has devastating long-range magic she'll use against you, she inflicts Frenzy and moves much, much quicker than you'd expect. You'll be relatively safe if you can stay behind her, but getting behind her at all is quite the ordeal.
