Batmud: Choreography of mutilation skill

I think this is the mastery for Spawn related powers. I think it improves the damage of clawed strike and possibly the chance to hit well with tentacles. But I don’t have any good info on this.

The ingame help reads:

Skill duration: random.
Type of skill : mastery skill.
Affecting stats: None.
It uses no endurance points.
Some followers of Azzarakk have developed killing and mutilation into a
chaotic form of art. While these followers are rare, the discipline is
terrible to behold.
