Atticus's entire focus was on his palm in contact with the mana barrier, trying to dissect and comprehend the intricate details of the mana signature contained in the mana barrier.
During this analysis, he meticulously fine-tuned his own magical output to mimic the specific signature.
Atticus stood with his eyes closed, not moving a single inch for more than 30 minutes.
And just when it seemed that nothing would happen, suddenly a burst of mana radiated from Atticus's core, immediately engulfing him.

Using the ethereal cloak, just like the environment, the mana enveloping Atticus would be as free and adaptable as the natural mana in the environment.
