Way of Resonance

Monks of the Way of Resonance have learned to manipulate their ki in order to create powerful sound waves and use them for various purposes. Founded upon the meditation of the cosmic sounds that resonate throughout the universe, as well as the appreciation of those sounds that come from all life, these monks can be found wandering the world in search of new sounds to meditate upon, hoping to one day reach enlightenment by becoming one with sound itself. To a resonant monk, all sounds of the world are beautiful, even those used to bring low their enemies.

Acoustic Attunement

When you choose this tradition at 3rd level, you gain proficiency in the Performance skill. If you already have this proficiency, you gain proficiency in one other skill of your choice. You also gain proficiency in two instruments of your choice.

World of Sound

Starting at 3rd level, you begin to develop extrasensory hearing as a result of your training and use of ki, granting you abilities when you reach certain levels in this class, as detailed below:

At 3rd level, you gain the ability to see the world around you through sound alone. You have blindsight, allowing you to perceive your surroundings without the use of sight, out to a range of 30 ft. Within that range, you can effectively see anything that isn’t behind total cover, even if you’re blinded or in darkness. Moreover, you can see an invisible creature within that range, unless the creature successfully hides from you.

At 5th level, your training with ki increases the base range of your blindsight increases to 60 ft, and grants you immunity to being deafened.

At 11th level, as a result of extensive training in combat, you have advantage on all Wisdom (Perception) checks that rely on sound, and other creatures don't gain advantage on attack rolls against you as a result of being unseen by you.

Sonic Magnification

Also at 3rd level, you have learned to use your ki to manipulate the sound that emanates from your attacks, causing the sound itself to deal damage. Once per turn when you hit a creature or an object with a weapon attack, you can deal extra thunder damage to the target equal to one roll of your Martial Arts die + your Wisdom modifier and push the target 5 feet away from you.

Art of Quietude

At 6th level, you can remove a creature's ability to make sound by interacting with their ki. When you hit a creature with an unarmed attack, you can expend 1 ki point to force the target to make a Constitution saving throw. On a failed save, the target becomes unable to speak or produce verbal components for spells until the end of its next turn.

In addition, you can touch one willing creature (this can be you) to grant them advantage on all Dexterity (Stealth) checks they make for 1 minute. You can do this a number of times equal to your proficiency bonus, and you regain all expended uses when you finished a long rest.

Blaring Counterstrike Technique

By 11th level, your training toward manipulating sound in combat allows you to instinctively release sonic explosions when attacked. Once per turn when you are hit with a melee attack, you can immediately deal thunder damage to the attacker equal to two rolls of your Martial Arts dice + your Wisdom modifier and push it up to 15 feet away from you.

You can do this a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

Soul of Resonance

Starting at 17th level, you have become attuned to sound at the very core of your being, allowing you to travel with it. Whenever you use your Sonic Magnification or Blaring Counterstrike Technique feature, you can immediately teleport to an unoccupied space you can see within 30 feet of you.
