When Lev was still in Tozir's grasp—within five to ten seconds—he activated his Necromancer skill. If he had been even a few seconds late, he would have completely lost consciousness.
[Skill Name: Necromancer
Description: Dead souls cannot be brought back to life. However, you can make their soulless bodies move according to your will.
Requirements: Only applies to corpses of people you have killed.]
According to the description provided by the Hero's System, the Necromancer skill could make the bodies of enemies he had defeated move according to his will.
Actually, he didn't really know that the skill he possessed was the Necromancer skill.
Back when he was alive on earth, he often manipulated the corpses of people he had killed to increase his combat strength.
It wasn't permanent—only for one use—but his ability, which was the result of Black Magic Authority, had helped him a lot in various critical situations.
