Unspeakable

----
Unspeakable is a Level 3 difficulty, located right in the middle of Terrifying and Catastrophic, making it more tougher than Terrifying, but right before the finale of the canon JToH chart. If this were to be put into the JJT difficulty chart, it's rating would be placed around 11.5, making it equal to the difficulty that is named Petrifying. 
This difficulty is rather harder and more onerous than Terrifying, and also as of the writing this currently the only sub-difficulty of it, but it can be called more elementary to surpass than the next difficulty, Catastrophic. Unspeakable is also classified as a difficulty that is in progress, and I promise that I will finish it tomoroww.
