I am ToS, the difficult tower in Ring 1: Limbo, with (4.88). My creator is zanychrome and T3mpl4te. I am mostly known for the long truss jump on floor 9. Not to be confused with Tower of Increasing Stress, an Intense difficulty tower located in the Forgotten Ridge. The Tower building kit uses my music zones. My music is the base music for versions 5.1, 5.3, v5.35, 5.4, and 5.5 of the EToH Tower Creation Kit. I got added on August 2018, along with ToKY, ToTS, ToR and ToC. And I got revamped on December 2, 2025.
