==Class 7 / Power 7 | The Borderline (Beyond Humanly Impossible) | TAS Impossible==
If you're a Class 7 obbyist, there is now a high chance of you not getting past this class. 99% of the difficulties here have at least some sort of red correlation. Probably because they were blasted into the volcano, and are now 15 times harder.
I won't even speak.

These difficulties are physically impossible, and are designed to make people demotivated. If to decide to continue, buckle up, because it's not getting easier from here. Found in unofficial chart.

==Class/Power 9 | Theoretical Impossibility==
Once we reach the theoretical difficulties, the difficulty ramps up to ridiculous levels. Comparison between difficulties stops at RoorXD, where each jump seems physically impossible. For example, you have to wait until the heat death of the universe or walk forever while playing Roblox. You got the hang of it as you progress throughout class 9.

== Class/Power 10 | Inexistent Possibility | Pure Hell ==
Obstacles in this class are beyond impossible, as only ridiculous jumps are demanding enough for this class, ranging from 30 stud jumps to gravity and god mode control. The size and ludicrosity of obstacles here start to ramp up VERY quickly, and you'd see most built joke towers are class 10 since it's very difficult to build ludicrously large obstacles. (I'm looking at you, TFD difficulty Obby Creator towers.) Many classical tower-related creations start to become more and more loosely applied here. You can take ToAST, remove its winpad, and call it a class 10 difficulty tower since this class does not rely on floating-point limit size errors unlike classes 11 and 13. However, this example is still possible to be completed by exploiters by creating a new winpad, which fully qualifies for a class 10 difficulty obby.

==== The Death Chain (Class 10 - Class 12)====
It's time to die. These difficulties are IMPOSSIBLE. (They're not sub-difficulties lol) Even harder than the legendary MegaDeath, despite being only High-Peak Class 10. Obstacle size multiplies by a lot here, and most of these difficulties feature outside sections. The obstacle size here grows EXPONENTIALLY, by a factor of two, which means jumps can range from 50 stud jumps to 50,000+ stud jumps.
Note: Recently, this chain has been getting a lot of attention. This chain is between difficulties MegaDeath and Limiting, and is owned by 4 editors. Any other difficulties in this chain will reverse existify. Currently, 18 removed difficulties used to be in this chain but were ultimately denied due to their impeccably garbage quality and names.
