Maybe they have to ring the bells, and keep them ringing until no more demons come. Given the choice, that's what she would do. But Ellis has said to make them stop, and the mission isn't hers alone.

So Laura ducks inside her bell so she can grab the clapper and hold it still, the bell still swinging around her. It bumps awkwardly around her body, but it doesn't chime.

She can see the bottom of a shade approaching, the formless part of it that seems to have oozed out of the ground itself. The shape of it puts a shiver down her back. Holding tight to the clapper, she lets her foot claws appear and kicks both feet out beyond the edge of the bell, slashing at the demon while she dangles there.
