The Silver Level skill [Flesh Erosion Trap] is quite unique, allowing it to merge the hands, feet, or even the sharp-toothed heads of attackers into its own flesh when attacked.
The essence of life for undead creatures is the soul flame, the flesh is just a vessel.
The Giant Brutal Butcher doesn't need to use its body as a prison, in fear of being destroyed by enemies.
If its body is destroyed, it can recover by consuming some flesh.
For instance, in a battle with a wolf beast, the wolf beast's forepaw is trapped in the Giant Brutal Butcher's body as soon as it strikes.
It's the same for biting.
This allows the Giant Brutal Butcher to control multiple targets at once with the Silver Level skill [Flesh Erosion Trap], becoming a mobile super glue.
The flesh of the Giant Brutal Butcher contains a high concentration of death qi and mold poison, along with other toxins.
These toxins will infect the flesh of the target while trapping them, posing a threat to their life.
