Thurimbar Rod

This rod is a magical Musical Instrument developed by the gnomes of Zilargo. While holding the rod, you can take a Magic action to produce auditory illusions that unerringly replicate the sound of any instrument with which you're proficient, with an effect similar to the Minor Illusion spell, with the sound emanating from the rod. To determine the quality of the performance, make a Charisma check with the Musical Instrument you're replicating. If you are proficient with the Thurimbar Rod, you can produce unearthly music unlike any natural instrument.
