Being vulnerable in this kind of situation is probably the worst thing that could happen to a magician. They are in front of Barbarians that are twice their size and Warlocks who have mysterious abilities using their Grimoires.
Once they made a mistake, they would be in trouble.
This is what happened to them as they didn't expect that the horde of Barbarians would use a deafening roar that is capable of immobilizing them…
Their Mana Barriers broke and the Tier 5 Body Transformations were canceled in that brief moment. It seems similar to Vincent's Mana Distortion but instead of manipulating mana, they used the sound waves filled with their bloodlust to break them down!
'Bloodlust! It's similar to the Demonic Cult! What's going on?!' Shane was shocked.
He did not expect this kind of attack to come from the Barbarians. They know them as a race that is incapable of mastering mana or other types of energies except for the Warlocks.
