Bell's Effects

The bell is activated when near the presence of a hidden door. Once in proximity, a refreshing tone will cause the bell to ring out. This chime can only be heard by the user.

After signaling the user, the bell will cause a pale blue light to gather, indicating the location of the secret door.[1]
