Torture Chamber Skip is the first Major Skip performed in any runs. It allows player to skip Grim Grips. For Nero/Dante, the standard method of executing this trick intuses Inertial CS loop.
General Info
Exceed can speed up the process from his Aerial Combo cancels but, it's much tigher and easier to fail with.
Nero's Inertia is generated by CS and his first slash of Aerial Combo controls the player's position before procceding to CS to push Nero backward to reach the platform.
New Game+ uses Calibur which is faster than CS loop.
Vergil must have V-Sync turned ON for this to work. Lady also does something similar.
