This page is currently a work in progress.
The main goal of this guide is simply to teach you how to survive the dungeon. Below that is a separate guide for whoever is brave enough to rush ahead of the main group.
The smart way is the way that the game is supposed to go, team work, if you’re anti-social, sucks bro. Here are some general rules that will help out everyone; Healers need MP, don’t take their MP pots away, Melee classes should be the ones to take out Oryx’s Living Floor, and Wizards and Assassins can help take out Commanders of Oryx quick with full MP. Try and stay in a group, lure things to stronger players and help save everyone. If you see someone get 
Armor Broken try and tank some shots for them, and if you see a Priest get 
Quiet, give them an MP pot or 2. Cooperation is key to surviving together throughout the castle.
Now I legally am obligated, (and by that I mean people in this game will not shut up when they die, and will yell at me for it if they die after reading this), to tell you this is a very bad idea, as much can go wrong. If you are planning to rush you must first see if others are planning to rush, as solo rushing is even more dangerous. Also what kind of rushers are they? There are the kind who rush to make sure only they can get the loot, i.e they don’t shoot Commanders of Oryx or Oryx’s Living Floor, or they are the nice kind that will try and back you up if something goes wrong. I quite honestly hate the former but appreciate the helpers. Either type of group you are following have the same pattern as of moving through the mobs, they shoot the walls on the sides, which side you will have to figure out on the way. If you see someone running on the left side, you need to run on the right side and circle back to them if you can. You should also deal damage to Knights of Oryx as they inflict 
Slowed, and Oryx’s Living Floor which inflict Quiet as you go by. If you are the person in the lead you can circle the enemies while aiming for the wall, or if you are really good you can throw off the enemies completely, allowing you to shoot the wall undisturbed. If you are in the courtyard I suggest you kill all the Brutes of Oryx and surrounding mobs in one BIG group, then ditch that group in the water, AWAY FROM THE DOOR, as to not kill other players. Then you can move on as soon as you break the next wall, in the middle preferrably, you can rush past the Commander of Oryx, but you will need to kill all the non Insect Minions, then break a side wall and the two Oryx’s Living Floors for the next rushers to join you. (Please note that soloing the Ancient Stone Guardians is ideal for Potions of Defense, with the Ancient Stone Sword (A.S.S.) being a rare UT drop.)
If you are fighting to help out and have fun doing it, kill any Haunted Armors that pop up as they will get more hits in then the Stone Guardians will. Try and help people survive here too, as many people try Realm of the Mad God every day for the first time in their lives, so let’s make it a good experience. When fighting, try and make sure to fight the Stone Guardian that is getting shot at the most (typically the purple one), this will make the battle go so much quicker. Once one of the Stone Guardians are dead, the other one will freeze up and fully heal itself only once, when he does this MOVE AWAY FROM THE CENTER OF THE ROOM, as this Stone Guardian is about to throw its sword, which is capable of insta-killing anyone if they are standing on it. When it is healing you can move above it and shoot at it to get an extra 500 damage on him while it is moving into position to throw the sword. Once it has thrown the sword it will be 
Invulnerable, but this is not a waiting game, you must shoot down the sword to continue attacking the remaining guardian. Once the sword is damaged sufficiently it will return to its guardian and the latter will go back to fighting like it usually does, until it decides when it wants to throw its sword again. Make sure not to stay in the middle too much. Also, if you get hit by the sword, you will be 
Paralyzed long enough to be hit by it again, so do not shoot the sword if you’re a sword user, ironic I know. As soon as you kill both of the guardians, enter the portal as fast as possible, unless you got a bag. If you got a white bag, count yourself lucky, take your loot and nexus if you want to play it safe.
If you are fighting to loot a defense potion you can increased your chances if you count out you doing 5k damage on both of the guardians, starting with the one less people are shooting at.
As a trickster or a rogue using the planewalker, it is possible to switch to another starting room(of the 4) by teleporting on a small water spot, (only noticeable while using uncentered view).
There is a secret boss named Janus the Doorwarden. In order to spawn Janus you must destroy every Suit of Armor within the castle.
Upon defeat, Janus opens up, transforming into the portal to the Court of Oryx. You will then spawn into a lone room with Craig, Interm of the Mad God, whom, after a bit of dialogue, will open portals to several lategame dungeons. Janus is an alternative boss fight that is unreccommended if you are not skilled and/or maxed enough to challenge the dungeons ahead. Also, choosing to enter the Court of Oryx means you will miss out on fighting Oryx (and his multiple forms) for loot.
Most of the time, a lot of players rush through Oryx’s Castle, leaving all of the monsters alone. Nowadays, most players DO NOT work together to clear the monsters. Leaving other players, good and bad in the dust. Most players nexus once the Stone Guardians are defeated because they are already behind, giving them no chance to find or get any of their wanted loot. For those who are left, it is recommended for them to defeat Janus to at least, get some decent loot and Potions of Vitality from him.
These guys are almost everywhere and are the main killers of the dungeon. They summon annoying Warriors of Oryx that can swarm around you. They are notorious for rushing onto players, instantly killing most with their Armor Break shots. Before rushing at players, it will stand still for a few seconds and then suddenly run at them, killing players who are caught off guard. If you see a Brute of Oryx, you must be careful not to get rushed on. Archers and Huntresses can easily keep it at bay by Paralyzing it and shooting it down with their bows. Rogues can cloak and knock it out easily without it knowing.
The minions spawned by the Brutes of Oryx. Like their master, they also rush at players, firing 360 shots that will critically damage players who fail to get out of their path of destruction. They can also drop MP potions to help fuel classes such as the Rogue to allow it to keep using his cloak, or any other class that has a useful ability.
The bane of most rushers. It will constantly spawn more insect minions, Providing it an almost invincible shield for protection. Any class that can pierce will provide themselves useful. Classes that can also distract or quickly put them out of submission will also provide themselves useful.
These guys also rush onto you, shooting shots in a star shape. It is advised to steer clear of them. Luckily, they have low health, making it extremely easy for classes to destroy them.
These guys shoot shots that Slow. They are also slow themselves. They will stand still, and then suddenly rush onto you for a quick and easy kill. Shoot them from a distance and then quickly back off once it begins to rush.
The weakest monster in the dungeon. They deal physical damage and are somewhat fast. Any class with decent gear can one-shot it due to its low health.
Like all of the monsters in the dungeon, it will also stand still and rush at you. It is usually stationary, shooting shots. Sometimes, it will enter a phase where it is Invulnerable and heal back to full health, and then continue to fight. Players should note the difference between them from the “fake” suits of armor and the real ones.
