Hector

Hector's claim wasn't just empty words. He had observed the automaton's ability and learned their limit from the other three representatives. 

"Although their ability to adapt was incomparable to what I've seen, their critical thinking couldn't be compared to a brain-boosted Magician." Hector smiled as he grabbed a short staff from the shelf assigned to their stage.

The staff was designed in a dark color and inlaid with a marking of a mythical beast from the northern continent, a winged dragon.

As he stepped on the stage, the Magic Formation activated and blocked all the noises coming from the outside. Hector then focused his sight on the copper automaton at the other side of the stage.

The 15 minutes timer had also started as soon as he entered the stage.

Hector activated his Mana Shell and cast an exclusive Mana Spell of the artifact. 

"Eight-Fold Roar!"
