Bagpipes of Resonance

This set of bagpipes are much like any other, except for oversized brass resonance bells on the ends of the sticks. This allows more time for the vibrations to build which creates a far more powerful, longer reaching sound - although the quality of tone is still an acquired taste.

For the purposes of checks where the output volume of your instrument may play a factor in success, your DM may allow advantages on ability Performance checks, circumstances permitting. 

This also allows you to boost your Bard spell 'Shatter', by adding 1d8 at second level, and 2d8 at any level above that, once per long rest.

If you have proficiency with a given musical instrument, you can add your proficiency bonus to any ability checks you make to play music with the instrument. A bard can use bagpipes as a spellcasting focus.
