With the multiple layers of magic on top of the stealth cloaks, Toz even had a hard time sensing himself. He was reminded slightly of his magic, Void's Embrace. If someone experienced the sensation of being hidden from themselves for too long, it wasn't impossible for them to lose themselves and go at least slightly crazy.
However, the effort needed to replicate it wasn't something that would make it worth the effort. Four mages, one with a unique inclination on top of a heavily enchanted cloak, all combined to hide Toz and the others away so that they could only rely on their sense of self to know where they were.
Toz and the others couldn't even tell where the others were. They could only rely on and trust each other. Thankfully, they had already gone over the plan together with the information Braxton had told them several times. As long as everyone remembered everything correctly and followed the plan, there shouldn't be any issues.
