Trident of Tapping - minor magic item

This trident can be used to tap on walls, floors and ceilings to ferret out hidden passages and chambers. The three blades of the trident will vibrate and ring out a harmonious note if there is open space within 5’ behind the surface tapped on. The exact note chimed will vary depending on the thickness of the surface. A full round spent tapping a 10’ square area will reveal the exact location of any secret doors in the area.

Use this minor magic item in your D&D 5e campaign or in any other pen and paper fantasy RPG.
