To reach the Cathedral of the Deep, you must first navigate through the Road of Sacrifices, defeat the Crystal Sage boss, and then proceed through the Cleansing Chapel area, eventually opening the grand doors to the Cathedral itself.
Just around the corner, to the left of that prayer group, you'll find an enemy wielding an axe. As you engage, watch out for another hollow enemy climbing right over the ledge! Once both are down, grab the Ember from the corpse. Then, simply open those grand doors you just passed to step into the impressive Cathedral of the Deep.
How do you raise the gates in Cathedral of the Deep?
To raise the main gates within the sprawling Cathedral of the Deep, you'll need to locate and pull the lever situated in the far left corner of a specific upper balcony area.
Before you rush in, try to clear out any ranged threats first, especially those pesky holy mages who can really overwhelm you with their projectiles if you're not careful. Taking them out from a safe distance gives you some breathing room to get to the lever without interruption. Honestly, this is a critical step! Pulling this lever doesn't just open one path; it actually raises a second gate, creating a crucial shortcut and a much-needed walkway across the upper levels. This makes getting around this complex area much, much easier, as detailed by the Dark Souls 3 Fextralife Wiki.
How do I get out of the Cathedral of the Deep?
To exit the massive Cathedral of the Deep, simply proceed through the prominent doorway found to the left of the knight guarding that particular section.
After you pop out into that big, open area, hang an immediate right. You'll transition from the waterlogged floor to some really muddy, treacherous ground. Here, you'll encounter tough Giant Slave and Rotten Flesh enemies; they can be pretty challenging and often show up in groups. While you can certainly fight them head-on (if you're feeling brave!), many experienced players find it more efficient to just roll past them to quickly reach the exit. It's a common strategy for speed and safety, mentioned in tons of community guides.
