Normally, Signum would be able to make a decisive strike right at that moment on an opponent as slow as Garviel...unfortunately, his armor is very good, and she's not about to claim victory by clanging Laevatein off of whatever monstrosity his plate was made of.

Besides, she knows that he knows that in a serious fight, this opening would be enough to cook him alive in there.

Instead, with a spin, she brings Laevatein's hilt around to crash in through the opening Garviel left with enough force to dent steel, hoping to knock the once-Berserker fully to the ground so she could feasibly put a point under his helmet.
