Spire of Truss

Spire of Truss, or SoT, for short is a scrapped spire that was originally going to be in Ring 1.

Due to the missing portal slot next to Spire of Killbrick Mayhem, and the fact that the other missing slot is in Psychologically Unsafe alongside the other removed spire being Spire of Wallhop Flicking, it can be inferred that Spire of Truss used to be Intermediate.
