Great Citadel of Impossible Void

== Introduction ==
__NOTOC__
Great Citadel of Impossible Void (GCoIV) is the final structure in Ring 10 in World of Slow Descent. It used to be located on a rock in the void. This Great Citadel is the longest structure in this world, being 220 floors and taking around 69 hours to beat, but 220 hours on a normal run with fails, due to long extensions and a lot of gameplay. There are ten droppers in total. The frame colors are the same as CoV but each floor color equals to ten floors here. So the final ten floors are rainbow. Every floor gets slightly darker, till the point where you can't see anything once you get to the bossfight. This monolith can only be accessed by completing a Aleph-Something obby harder than the entire Lava King Monolith in Zone 10. The obby is hidden so well, that even FINDING it is RoorXD. In practice time, some features are noclip, heal, godmode, tp tool, portals for each floor with a portal room and the most important of all: the orb system.
Tower Type: Omnipotent Great Citadel (ascension, descension, sideways progression, slanted progression, wacky frame) 
Difficulty: Peak Ooo Above Catastrophic ooO (2023 difficulty: maybe around low Omega-Omega)
== Orb system ==
There is a orb system in the old version GCoCIaND that is forgotten about. This is a revamp. Under each orb, there will be a description and cost. The orb system will be used in the lobby. Note that orbs save after you die. You will really need them, especially for the brutal floor 220. Note that orbs can stack, but the effects won't be any better. This is only available in practice time, so this won't butcher the difficulty of GCoIV to LOOP or something.

====== Floor 163: Peak Dilly Impossible ======
THERE IS A SUPERSONIC INSTAKILL SPINNER GOING AROUND THE ENTIRE FLOOR. YOU'RE DEAD.
====== Floor 164: Bottom Monstrous ======
The next 10 floors of gameplay are a slight break compared to the rest of the great citadel.
====== Floor 165: Mid Ultimate ======
====== Floor 166: Mid Supreme ======
====== Floor 167: High Quantum ======
====== Floor 168: Peak RoorXD/Jesus Ballin'/Bottom Hyperwave ======
This floor has a 30 stud jump on the outside section.
====== Floor 169: Low MegaDeath ======
====== Floor 170: Mid 60mmm ======
====== Floor 171: Peak Malicatious ======
====== Floor 172: High Hopeless ======
====== Floor 173: Mid Dilly Impossible ======

However, the next 23 floors are very punishing, as it is all outside. It doesn't introduce any new mechanics but does use them in weird ways.
====== Floor 175: High Imaginary ======
====== Floor 176: Mid Errorisation ======
====== Floor 177: Mid Imperceptible ======
====== Floor 178: Bottom The Crystal Core ======
I enjoy seeing you suffer outside, I really do >:).

Drop down to floor 164.
====== Floor 196: Peak The Middleline ======
There is a boss-fight. The boss (131073c) says that you have not met his true form yet, and that he was only getting started. The bossfight is incredibly hard, with around 100 attacks, and 5 phases. He has about 1 centillion hp and instant kills you. 131073c when defeated, sends you to floor 197. 
=== THE FINAL STRETCH ===
Even looking at the floors can give you a seizure at this point. They are ascension floors.
====== Floor 197: Peak Unbearable ======
These difficulties are all at their max form and it gets 1 difficulty harder every floor! This floor has millions of super sonic instakill spinners.
====== Floor 198: Peak Scary ======
====== Floor 199: Peak Imposter ======
====== Floor 200: Peak 1700s Sea Shanties ======
====== Tower Crossing ======
HAHA THIS TIME YOU HAVE TO BEAT THE ENTIRE LAVA KING MONOLITH
====== Floor 201: Peak U will die ======
====== Floor 202: Peak Aleph-Something ======
This is the final and hardest purist floor. It has purist jumps that one cannot imagine. The final jump is to... JUMP THROUGH A 100 STUD FREAKING WALL.
====== Floor 203: Peak Very Harwfd Difficult! ======
This is a GAT floor.
====== Floor 204: Peak BLACK DEATH ======
====== Floor 205: Peak Perfect ======
====== Floor 206: Peak KAPHTEEZ ======
====== Floor 207: Peak LOOP ======
This is the longest floor in the whole great citadel, beating out even floor 220. This floor takes about 24 hours to do on average. It is just spamming the same The Crystal Core difficulty jumps over again so there isn't much to talk about. It is also unimaginably hard. One obstacle in this floor is walking forever.
====== Floor 208: Peak El Octo Vacio ======
====== Floor 209: Peak YOSHI HAMMER ======
This floor is 200x200. It is the second biggest floor except for of course floor 220.
====== Floor 210: Peak War Crimes ======
This floor features a unique obstacle: laugh clipping through the disconnection screen.
====== Floor 211: Peak % ======
====== Floor 212: Peak Questionable ======
====== Floor 213: Peak Misery ======
====== Floor 214: Peak Tediously Impossible ======
====== Floor 215: Peak Purgatory ======
====== Dropper 10: Low YOSHI HAMMER ======
This is the final and hardest dropper. You have to drop all the way down to... FLOOR 1. Not only that, but at the bottom of the dropper has a very long and very hard outside section over kickbricks. And remember the spinner from floor 163? There are 10 of them now, over the entire outside. Then do the highest jump in this whole great citadel: a 21,500 stud high jump. There isn't any way to cheese it.
====== Floor 216: Peak IMPOSSIBLE.EXE ======
====== Floor 217: Peak TooRNG ======
====== Floor 218: Peak Felix the HET ======
Do that infinite stud glitchwrap.
====== Floor 219: Peak TooTooHard ======
This floor is mostly purist, but one notable obstacle here is to walk through cancollide true instakills. Some obstacles include walking through 200 stud thick wall spam. This floor has a final jump. The sign says "uhh do this 1 nonillion stud jump thxs". Once you do the jump, you get teleported to ERROR 404: FLOOR 220 NOT FOUND+CORRUPTED. Also, the portal is a kickbrick like ToYM2 so good luck.
====== Floor 220A: Mid El Octo Vacio ======
Floor 220 is 500x500x500. It is split into five sub-floors, making each floor 500x100x500. Each one gets MUCH harder than the last. This floor is full of kickbrick spam. There is a instakill spinner with a velocity of 652 spinning around, so yo'ure dead in a few microseconds. There are also conveyors dragging you back at speeds of 2,147,483,647. And the conveyors are also 0.00001x0.01 and are placed 200 studs apart. There is no reason for you to even try this floor. This is slightly easier than floor 219, but much longer.
====== Floor 220B: Low Misery ======
This floor has many absurdly hard RNG flings on outside sections landing on 0.001 stud cancollide false instakills. There are so many inescapable GBJ's that when you try to escape, you hit a kickbrick. There are also obstacles from the previous floor but the conveyors are outside over inescapable GBJ's, cancollide false instakills and placed 10,000 studs apart. Then you have to do NEAT but every block flings you! Once you hit the winpad you get teleported to floor 220C.
====== Floor 220C: Bottom Purgatory ======
This floor has many fling bricks that flings you onto instakills. There is insane client objects that are hardly buildable. There are even more kickbricks, conveyors and cancollide false blocks. There are lots of instakill spinning beatblock wallwalks. Escaping the SC VM barrier ten times in a row is just one normal obstacle in this floor. This is the floor before everything becomes extremely hard to build or even describe.
====== Floor 220D: Peak Felix the HET ======
Ok. This is beyond what most people can even comprehend. Every block here is placed 500 studs away. They are also 0 studs big. They are cancollide false flinging instakill beatblock 1 septillion speed backwards dragging conveyors. It's so dark you're basically blind at this point. If you fail even once, you fall onto the permaban floor and you're banned. This is easier than floor 219, but it has more quality because floor 219 spams the same jumps over and over again and uses no client objects at all. After you're done, you get teleported to TRUE finale: floor 220E.
====== Floor 220E: Low Ooo Above Catastrophic ooO ======
Every obstacle here is literally incomprehensible. If you do one jump here, you get a existential crisis. It is not for people that are scared of obbies. Here are some examples of obstacles. Floor 220E doesn't want you to enter. Obviously, you already can't beat this, it's quite obvious but you have to first enter. There are 3 parts to hacking this. First, you must enter the code. Simple, right? The code is 18 characters long. Even worse, the system goes into lockdown mode if you get the password wrong around 16 times. First, you have to practice getting past the floating point. This can be done by using mid-air fling control to fling yourself past the floating point so far that Roblox can't perceive where you are. But now what? Well, you have ascended past Roblox where other universes lie. You can go to other universes, but in here, physics is weird as it is the middleline between multiple worlds. You need to find the perfect rift to abuse physics enough. Now it is time things get a bit messy. You've already distorted the void enough to allow physics, but the structure you are in is not in the rift. To do this, you need to distort time, so you can have the same fling effects and how Client Objects work differently. First, you must travel facing northeast and slightly up. Why? That's the direction of the source of time. Now, you must go in two different directions, one towards Aleph-Null and the other direction towards Supreme. This can be hard, as they are probably both down by a lot, so you must be incredibly accurate. The last thing you have to do is jump. As you know, jumping here can be extremely hard. But you must do this at the exact moment the time core slightly wanes, as it is slightly weaker during that time. This process has to be extremely well-timed, as you must jump right at the moment you create the slight crack in time. Now, you have split the core, and created two timelines. You're almost there. After you've created the two timelines, you have to do something quite difficult. You have to create a bridge of the floating point in the other universe to this universe. This can be done by enabling the Reality Switch, but you have to turn it to around the 36.942 degrees. Then, locate the direction of NeaT and use the Reality Switch to reflect NeaT's parts to create a reflecting bridge. But the bridge is dependent on NeaT's reflecting parts. So, after you have done this, construct a direct copy of NeaT, and then Z-fight it with WBaT. Then, turn towards ToSO and harness the truss on the inside to solidify the bridge. After you have done this, the realities have been linked and you can travel into the alternate timeline. This can be dangerous, so on average you will need to do this process 1,832,348,873,052,831 times to find a timeline that has not been corrupted or destroyed. Once you have done that, you have finally created the bridge to the bossfight.
=== Bossfight ===
OK. I HAD ENOUGH OF YOU. I'M TALKING TO YOU IDIOT, SANJAY2133. STOP THIS. THE BOSSFIGHT IS COMING.
====== Phase 1: Peak U will die ======
The boss has a googolplex HP and does a googol hits a second. It also does infinite damage. You have a weapon that does 12 damage. LOL.
====== Phase 2: Peak LOOP ======
You thought that was it? It's not. The boss has infinite HP and does infinite hits a second. It also does infinite damage. You have a weapon that does 0 damage. It's so dark that you're blind. (Insert trollface)
====== Phase 3: Peak Ooo Above Catastrophic ooO ======
Finally you're here. The boss has NO hp and does NO damage. Even the darkness goes away. He's just here watching you suffer. Even the boss cannot withstand the next obstacle-
 ERROR 404: GREAT CITADEL GLITCHING
You've even more screwed than any other time in this entire great citadel, because you've come across a time wrap! In order to activate these, you must go to the furthest omniverse, and find something closer to your house than your house, or wherever you live. You can use these to do leaps in jumps. Using these more than foures will insta-kill you from existence, so be careful. So heres how to use this mechanic (Bold = Important)
# You must travel in time exactly 0.4(random digits, lets say ours is 20228028301929292802920 and so on until arrives) after you do a jump, then use it and jump spontaneously instantly right after.
# You must calculate PIX401 (x 401) which not only do you have to count all the digits of pi, but you have to do all of them multiplied by 401, so the script is flipped in that time section with the numbers you got from the time warp.(0.445822208202839293 and so on until- you know what, you get it, right?)
You could not have done that, not at the class 15 to baseline class 16 skill level..
You've beaten the great citadel.
== Ending ==
You are taken to the largest winroom ever, at 10000x10000x10000 studs. Everyone in the obbying community will be congratulating you. You've already done one Destroiny obstacle, why not finish the entire difficulty? You will get even more GG's if you do it. But take some breaks and don't forget to touch grass.
