You can go to Everfall by either jumping into the pit from the main square (Gran Soren) or by going through the door which you used for the quest “Lure of the Abyss” at Pawn Guild.
Dragon’s Dogma Everfall Chambers
Chamber of Confusion
As soon as you enter the chambers, you will have to fight the Evil Eye. You cannot proceed any further without slaining the Evil Eye.
Make sure you have a couple of items to cure petrification as he’ll poison you many times. The best way to attack him during his shield on is to attack the tentacles, once the shield is off you can attack him head-on.
Repeat the process unless you successfully defeat him by attacking on its eye. Once the Eye is defeated, you can access the other chambers.
Chamber of Anxiety
Holy and Boon Affinity are useful when the Wight is casting spells on you. Make sure that you clear the skeletons before you attack your heavier enemies.
It should be like Skeleton Sorcerers>Skeleton Knights and then the Wight, which is not very difficult. Just stay out of the red circle where his magic is casted.
Chamber of Abscence
Take out the Skeleton Mages after you have crossed the bridge, then aim for the tails of the Geo Saurians so they’ll take more damage.
Move downstairs and then fight a single pack of Hellhounds at a time, if you’ll attract more than you might die easily. Long ranged attacks are the key here, Boon/Ice Affinity is helpful and so are the ice attacks.
The second room has all the Goblins; they are really easy to kill. Stay back in the hall away and let them group together so you can easily take them down.
Chamber of Hesitation
ENGAGE ONE AT A TIME and cut off the tail whenever you are dealing with the Saurian Sages. The second room has Undead Warriors and Archydra (boss).
Take out the warriors, so they won’t bug you and their boss. Make sure that you have lots of health items. Just keep on attacking its neck and climbing up, when you cut off the head – use fire attacks so you can permanently stop its growing. Taking out all four heads will make him vulnerable.
Chamber of Apprehension
The groups in this chamber are spawned randomly, and so are the chests. One of the groups has the Wights and Gorechimera. Use a ranged weapon to take out the Wights with the help of Holy Affinity. When you reach to the Gorechimera, try taking out the snake first so the beast will get vulnerable.
The goat will cast healing spells to regenerate the health so it should be your second target. Strike the head when you’ve done the last two jobs, if the snake grows again you can just repeat the process.
You must carry some items to cure petrification or wear armor to resist yourself from the poisons of the second group. Take out the Grim goblins ASAP and then the Cockatrices, focusing on a single target is better than damaging them one by one.
Chamber of Remorse
Easy if you do it properly, the Grim goblins will ambush you in the second room and are accompanied by a Golem on the bridge. Take care of the Grim goblins and then move towards the Golem.
Try not to make the Golem fall down, and if it does, don’t fall with it. It will be tougher to face all of them together so if it happens, go down-stairs and attack the Cyclops first and anything which comes with them.
Chamber of Tragedy
Take out the winged enemies with the help of your long-range attacks. The Gargoyles and Succubi are faced separately but there is a chance of facing a couple as well.
Magic-based attacks are strong on Specter, fire based on the Succubi and the Lightning based on the Gargoyles.
Chamber of Lament
This level has two types of Ur-Dragons (offline and online). Both are very much different from each other; the offline one is just another monster of the game.
