Wand of Pyrotechnics

This wand has 4 charges per day.
While holding it, you can use an action to
expend 1 of its charges and create a harmless
burst of multicolored light at a point you can
see up to 60 feet away.
The burst of light is accompanied by a crackling
noise that can be heard up to 300 feet away.
The light is as bright as a torch flame but lasts
only a second.
