Minotaur's berserk

Suddenly, its muscles bulged, growing even larger as it employed some kind of body-strengthening magic. With incredible speed, it burst through Lucius's wind barrier, sending him tumbling across the stone floor. 

The tide of the battle shifted once again to its favor as it broke free from Lucius's entanglement. It was already ferocious enough. But now that it grew in size, it exuded an even more threatening aura. 

Its movement became sharper than ever. At the same time, its strength surged to an unprecedented level. 

Immediately, Kaiser lashed out with Naga, the whip-snake wrapped around the Minotaur's arm, barely limiting its movement. This action of Kaiser barely prevented Lucius's death. If not for him, it'd have pounced on Lucius with its massive arms. 

Though he prevented it from advancing on Lucius, he found it extremely difficult to restrain it. This took a toll on his body as he tried to keep it from advancing.
