Fairer Potion
Ignacy has a few techniques in his arsenal that allows him to use his consciousness to affect his target. It may not be as strong as those Magic Artifacts that specialize in this technique but it is still very easy to cast and only requires a brief moment to activate.
As soon as Vincent mentioned using their consciousness energy to attack, he didn't hesitate and followed it since they have no better choice.
The barbarians were advancing and not giving them time to try their Magic Tools or ephemeral mana arts.
Since time is not on their side, he used his Command Inducement to one of the tattooed Barbarians. Normally, this technique isn't that powerful and could only affect weaker mana practitioners.
He commanded the barbarian to step back.
It is a simple command. If the barbarian followed his instruction, then Vincent was truly their lifesaver.
