I didn't realize the changes in the Versatile Weapon. In fact, the weapon's name has changed and is now displayed as Blood Covered and Sinful Versatile Weapon. I think I can see why it got a new name just like that. With this weapon devouring at least 3 weapons of the Seven Deadly Sins weapon series, I can say that it's very close to completing the weapon series ending up on its bottomless stomach.
Checking on the new skill of the weapon, it seems the Sloth exclusive skill was a buffing skill. I thought it would be control but it was more of a beneficial continuous buff. It's a very good skill as it buffs the party members while giving debuffs to enemies who can hear the song. It's a little too good. And the caveat on this skill is not much of a problem as well even though it leaves me vulnerable while the skill is active and even though it cannot be canceled, this skill is considerably quite powerful in teamplay, and in case I don't want to fight much and prefer to go full support.
