The【Soul Break】that he had acquired after destroying Sercrent’s soul was a particularly powerful skill.

Upon careful inspection, it had turned out to be a skill that dealt damage to Mana equal to the amount of damage to Vitality that Vandalieu inflicted.

If he dealt damage to Vampires with this, their Mana would stay damaged even if their Vitality recovered immediately, so this skill would be effective to use in battles against Vampires. He would even be able to drain the Dragon Golem of the Mana it used as its power source… if he could damage it.
