Each individual labyrinth has its own unique layout, but they all follow the same basic pattern. All dungeons start with a chamber of the seal, which is a small room with a lamp in it. That leads into a linking corridor, which in turn leads to the layer Lamp Linking rooms can have doorways on the right or left that lead to optional paths, the goal of which is a treasure room with a coffin to loot Once you've opened the coffin it's safe to head back to the linking room to progress.

Every labyrinth has at least one locked exit gate per layer. Once that door is unlocked you'll have a clear path to the boss, though there's usually a linking room behind the door that may contain another optional path. The layer Lamp is very often near the locked exit gate, as in the example here. This ensures that if the boss defeats you, it won't take you very long to get back and try again. With Lamps being as frequent as they are you'll never have to travel far to reach one, so taking frequent trips back to the Hunter's Dream to repair your weapon, upgrade your character and ensure you're fully stocked up on consumables is highly recommended.

Doors/Gates:
While the doors and gates you come across in dungeons may initially just feel like they're there to halt your progress, they do convey useful information once you know what to look for. At the start of each layer you'll come across one or more bronze doorways, and a pair of statues holding flaming torches will surround one of them. Those torches are used to let you know that the path beyond that doorway is the one that will eventually lead you to the room containing a lever that must be pulled to open an exit gate.

The door without the flames will always lead you to optional parts of the layer, where you can get some extra loot. Finding the locked exit gate is rarely a problem because they are almost always placed in plain sight, as if taunting you, and they're easily identifiable due to the statues holding a blue flame on either side. Once you pull the lever associated with that gate, those flames will turn from blue to a normal yellow flame, letting you know it has been unlocked.

Gate Lever Rooms:
These rooms will usually be some of the most heavily-defended ones in the dungeons, and you'll often have to battle your way past large groups of regular enemies, a single strong one, or sometimes a combination of both. A cautious approach is called for when entering one of these rooms, and with patience you'll often be able to lure the enemies out one at a time to make the fight easier, and sometimes you can take advantage of room layouts to let you get behind enemies without them noticing.

Treasure Rooms:
Similar to the Gate Lever rooms, these rooms should be one of your primary targets in any dungeon. You'll often have to make your through a challenging gauntlet of traps and enemies to make it to these rooms, but once inside there's often only a single enemy guarding the chest(s). The contents of these chests are often large quantities of valuable materials for creating dungeons.

Secret Paths:
Once you start recognizing each room type, you'll notice that the door placements in each one will either be open or blocked off depending on how the room is arranged in the layer/dungeon you're in. These blocked off doorways are the most common places to find hidden walls, so a good methodical way to discover them is to simply attack every blocked off doorway that you come across. Short, dead end corridors or long pathways leading to seemingly nothing can also signify that a hidden wall is nearby, so it's important to check those as well. A single hit with a weapon is all it takes to remove the illusionary wall.

Bridges Layer Skip:
It is possible to skip dungeon layers using the rope bridges in canyons, for more information visit the Skips wiki page.

Environment, Traps & Hazards

Hoards of enemies are not the only things you'll have to contend with in dungeons - there are also numerous fiendish Traps & Hazards that are trying their best to kill you. Once you know where the traps are, and how they work, you can even use them to your advantage by luring enemies into them for easy kills.

The Illusory Walls are present in Chalice Dungeons you can find them in preset Lower Pthumeru or various Root Chalice Dungeons. They emit a windy sound similar to the one you hear before fighting a boss in the dungeons. You can reveal such wall by hitting or rolling into it.

Floor Messengers: Certain doorways and openings into rooms will have unlit lamps on the floor near them and when you enter those rooms, helpful messengers will light the lamp with a blue flame. Once the lamps are lit you can use them as markers to let you know which rooms you've been into in case you find yourself getting lost.

Dungeon Gameplay

While most of the skills you acquire from the main game will carry over into the dungeons, there are a few differences In this section we'll go over some basic tips about the different types of elements found in dungeons that will aid you in your exploration.

Dungeon Dwellers:
You'll encounter some familiar enemies from the main game in dungeons, but for the most part you'll have to contend with new enemies and have to formulate new strategies to deal with them. Some of the layer bosses will sometimes return in later dungeons as regular enemies, so you'll need to adapt to fighting them with other enemies present. The opposite is also true; enemies that you have encountered normally (such as Brainsuckers) can show up as bosses with much higher stats, forcing you to again reevaluate how you approach them. It's also important to remember that most Strong enemies within dungeons drop Basic Materials that are used in dungeon creation, so killing them all is extremely important if you want to create multiple dungeons.

Bell Ringers: One other thing worth noting is that Bell Ringers are among the greatest threats in Chalice Dungeons, because they continually summon more enemies you'll have to deal with. Locating them quickly is therefore very important, so get used to the places they tend to appear in. By far the most common places are on the ledge in the multi-level room with stairways on either side, and at the very top of the three-story circular room with the stone elevator platform in the middle.

Using the Environment:
Most rooms in the dungeons are connected via doorways or narrow tunnels, and thanks to this, if you enter a room that contains a formidable number of enemies, you can always retreat back and funnel the enemies through it so that you can deal with them in more manageable numbers. Doing this is an almost essential tactic once you start getting into the high difficulty dungeons, so becoming comfortable with doing it early on will help you considerably in the long run. Always check the ceilings when entering rooms, because the dangling roots and murky corners are often home to Nightmare Apostles and Gels that are just waiting to drop down onto you.

Hand Lantern: If you haven't already done so, it's worth investing in the Hand Lantern from the Bath Messenger in the Hunter's Dream, because it can get very dark in some rooms (especially in Loran Dungeons) so every little helps. This is especially true if you primarily use a transformed 2-handed weapon and cannot carry a Torch normally. Equip the Hand Lantern in your Personal Effects to keep your Quick Item slots free for other things.

Stay Powerful:
Your character and weapon levels matter even more in the dungeons than they do in the main game, so making sure your weapons are as upgraded as possible and taking frequent trips back to the Hunter's Dream to level up are very important. If this is your first playthrough it's recommended to stick with one main right and left hand weapon and focus on fortifying them. A second right hand weapon can still be very useful, especially if you're making weapons to take advantage of enemy elemental and type weaknesses; having dedicated fire and arcane/bolt weapons will help you considerably against some of the tougher opponents you'll encounter in dungeons.

Room Types:
Although there are many different types of rooms used in the dungeons, if you pay attention as you go through them, you can start to get familiar enough with the types to almost know what's coming up just by looking into a room. The different types of dungeons will often try to camouflage the rooms by covering them in roots or similar environmental objects - try to disregard these while keeping track of the room types.

Depth Order:
Finally, while you can bypass some of the earlier dungeons if you wish, it's recommended that you do them all in the order of depth so that you can used to the way things work as you build up to the more difficult ones. The depth two and three dungeons can be a very good source of Blood Echoes if you tackle them at the appropriate level, especially the Root versions with some Additional Rites. Once you get up to the depth four and five dungeons, however, it's recommended that you attempt them in co-op with other players, because while you may be able to handle the normal enemies on your own, the bosses can be extremely challenging even with a team.
