Toz almost groaned in frustration at the restriction that constrained his consciousness before he realized it wasn't the restriction's fault he couldn't leave his body with his mind. It was a defensive measure to prevent himself from injuring his mind by exposing it to the outside world without the support of mana.
Toz had no trouble expanding his consciousness to absorb and convert mana when he trained. But trying to do the same thing without the support of his own mana proved a lot more challenging.
However, he could feel that the resistance hindering his consciousness from leaving his body wasn't as stubborn as the layer covering his mana pool. Toz felt as if he could pierce through the resistance as long as he tried hard enough. But he wasn't sure if he should.
Bringing his bare consciousness outside his body without the support and protection of his mana could very well lead to it getting injured or his mind suffering harm.
