Bell

The Bell is an interactive object in the Duality dungeon, where it is used in the boss fight against Caiatl. Shooting a bell from afar transports players into a Nightmare, and players must stand inside the circle around a bell to return safely. Certain enemies called Bellkeepers can lock a bell, making it unusable until they are killed.

During the stun phase, kill the Bellkeepers on the side Caiatl is approaching, then shoot that bell as she closes in. The hit stuns her and opens a short damage window; this repeats three times per phase. Standing close to the bell used for the stun grants a damage bonus.
