I am Challenging, the 5th difficulty in JToH. There are 46 towers, 11 steeples and 2 mini towers assigned to me. I give guides to people who are stuck at a tower that is assigned to me. Tower of Stress might be your first challenging. Try not to fail at the harder jumps on Floor 7, or landing on the long truss climb on Floor 9. Let me know if you get stuck at a challenging tower, then I will help you. Good Luck on beating challenging towers in the future!
