Tower of Obnoxious Altitude Sickness

The Tower of Obnoxious Altitude Sickness (ToOAS) is an Expert difficulty tower, with an unconfirmed JToH difficulty, although a good hypothesis might rate it as a soul-crushing tower.

This tower involves climbing a mountain, spanning from Floor 1, to Floor 10, and it can be a surprising challenge, as the higher you go, the more slippery parts appear, and interestingly enough, the music becomes more tense the higher you go, and this tower is exactly based on a specifically high mountain as well, one example is Mount Everest in the Nepal-China border.

This tower starts off quite simply, just some falling platforms, then rapid jumps, but gets increasingly more difficult the higher you go anyway, regardless of the sheer amount of challenges you'd have to do to complete the entire tower yourself, as the "mountain" is encased inside the tower.

It's a themed tower itself, along with several complicated difficulties to hold on to, as there are specific items that are seemingly required for the player to try it out entirely.
