Challenging

Challenging is a difficulty in KET that is represented with a dark red color. At this difficulty level, you will see a lot more obstacles that are similar to those of Intense and Remorseless, however more simple. These towers are near impossible for the average ROBLOX obbyist without trying genuine hard obbies first.

Towers of this difficulty require you to be a "true obbyist", dedicated to obbies and basically play them for a living.
