The black lines of rot under his left cheek dipped and wavered.
The curving line of the circle wavered in the light.
The line wavered at its most immediately threatened point, then stiffened again, stood firm.
The line wavered like a branch in a breeze.
Five, six, seven Vampires toppled to the red dirt and the line wavered.
Blade saw the line of spears waver for a moment, but then it steadied.
Shapes do not hold spatially; lines waver out of control.
Not a line of the scene before them so much as wavered.
Not many were thus disabled, but their line wavered and slowed.
The line of men clambering up the seats toward them wavered and broke.
