Metronome: A metronome is any device that can keep a regular, steady beat. Bards use them for all kinds of performances, including music, chants and various plays. Most metronomes are mechanical in nature, but a few are magical constructs that keep perfect time. A metronome can also be used to create a distracting environment (counts as a distraction for everyone who fails a Will save (DC 15)), as its regular ticks can startle anyone within 20 ft. of the device. Metronomes cost anywhere from 10 gp all the way up to 200 gp, depending on their construction, reliability and materials.
