A skill that augments one's aggression in battle. It appears to be a positive skill, but the longer its owner stays in battle, the more their abusive disposition will grow, causing them to lose their usual composure. It's possible to say that this is just one step short of the skill that causes Berserkers to go insane.
The more one attacks, the stronger one becomes, but on the other hand, one's defensive abilities drop. With the added disadvantage of unconsciously lowering one's chances of escape, it can be said that this is a skill that had bad compatibility with the usually composed Meltlilith.
