Monks of the Way of the Melodic Spirit have learned to channel to their ki to create an embodiment of themselves in an instrument. They've spent years meditating, honing their spirit into a physical representation of themselves in the form of a Spiritual Instrument. As they travel and grow, they learn to sharpen their ki to create a whole orchestra of Spiritual Instruments.

Spiritual Instrument

Starting when you choose this tradition at 3rd level, you mold your ki and gain a Spiritual Instrument. The instrument can take the form as any instrument you want and you gain proficiency in playing it.

You gain the ability to attack with your Spiritual Instrument and new attack options that you can use with the Attack action. These special attacks are ranged spell attack. You are proficient with it, and you add your Wisdom modifier to its attack and damage rolls. The damage type is force and its damage die is a d4. This die changes as you gain monk levels, as shown in the Martial Arts column of the Monk table.

When you gain the Extra Attack feature, this special attack can be used for any of the attacks you make as part of the Attack action.

Harmonious Bolt. You create a magical bolt of sonic energy. Target a creature within 15 feet of you and make a ranged spell attack, if it hits, the target takes damage equal to your Martial Arts die.

Concerto Shockwave. Spend a ki point to create a shockwave of magical energy from your Spiritual Weapon in a 10 feet cone. Each creature in the area must make a Dexterity saving throw against your ki save DC, taking damage equal to a roll of your Martial Arts die on a failure.

Concordant Strike

Starting at 6th level, you can your Spiritual Instrument become more intuned and can make cordinated strikes. Whenever you make an unarmed strike, you can spend a ki point to attack the same target again with a different attack option.

Additionally at level 17, whenever you make an unarmed strike you can spend ki points up to the amount of Spiritual Instruments you have to make an action for each.

Euphonius Weapon

Starting at level 11, you imbue more of your Spiritual Instrument with your ki. Your Spiritual Instrument becomes a spectral weapon.

As a Bonus Action on your Turn, you can move the instrument up to 20 feet but not more than 40 feet away from you and use an Attack action.

Starting at Level 17, you split your spirit to create another Spiritual Instrument. As a Bonus Action on Your Turn, you can move all of your weapons up to 20 feet and make an Attack action for each.
