The only way someone could beat a 3rd stage Body Formation Maugnetic like Arsonny was if they had a magic realm of 7-star or higher. But that was just the theoretical idea. Real life fighting was much more complicated, and a Maugnetic could easily overpower an 8-star realm magician if they used their Aubilities correctly.
The only one who could have defeated him was Seberus Augindore, an 8-star Tower Master back in the Kings region. But, from what they knew, Arsonny hadn't left the Queens region as of yet so he couldn't have encountered someone as strong as Seberus.
"Could this be a hoax?" Bobby asked. "Maybe he purposefully left his armor so that he could escape."
The other two nodded, feeling that this was the most logical explanation as to what had happened.
It was that, or there was a 3rd stage or higher Maugnetic in the lower Queens region. But that was very much unlikely.
