  Otherworldly 
  Patron 
  The beings that serve as patrons for warlocks are mighty 
  inhabitants of other planes of existence—not gods, but 
  almost godlike in their power. Various patrons give their 
  warlocks access to different powers and invocations, and 
  expect significant favors in return. Some patrons collect 
  warlocks, doling out mystic knowledge relatively freely or 
  boasting of their ability to bind mortals to their will. Other 
  patrons bestow their power only grudgingly, and might 
  make a pact with only one warlock. Warlocks who serve 
  the same patron might view each other as allies, siblings, or 
  rivals. 
  The Spirit of Jazz 
  When legendary jazz musician Howlin' Jimmy Jefferson 
  was dying of strange swamp fever, it is said that he 
  recorded one last album, smearing a drop of his own blood 
  on the record. The album itself is lost to time but, in 
  making it, Jimmy liberated his soul to wander the world as 
  the Spirit of Jazz. To this very day, his apparition has been 
  known to appear to aspiring musicians, offering them a 
  piece of its power in exchange for ownership of their souls.  
  Expanded Spell List 
  Your pact with the Spirit of Jazz allows you to choose from 
  an expanded list of spells when you learn a new spell. The 
  following spells are added to the warlock spell list for you. 
  Spirit of Jazz Bonus Spells  
  Musical Secrets 
  At 1st level, you learn the vicious mockery cantrip, which 
  counts as a warlock cantrip for you and doesn't count 
  against the number of cantrips you can learn. Additionally, 
  you gain proficiency with all musical instruments and 
  always use Charisma for any ability checks relating to 
  music. You can use a musical instrument as a spellcasting 
  focus for your warlock spells. Lastly, you can spend 1 
  minute working with whatever materials are lying around 
  to construct any kind of musical instrument you desire.  
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
  These improvised 
  instruments are useless to 
  anyone except you. 
  Sax on Fire 
  Also at 1st level, you can use an action to play a musical 
  instrument and allow your body to be possessed by the 
  Spirit of Jazz. This releases a blast of funky mojo, forcing 
  creatures in a 15-foot cone originating from you to make a 
  Wisdom saving throw against your warlock spell save DC. 
  Each creature that fails its saving throw is deafened until 
  the end of your next turn. 
  Smooth Talk 
  At 6th level, you can channel the supernatural charisma of 
  your patron to convince almost anyone of almost anything. 
  When you make a Charisma (Deception) or Charisma 
  (Persuasion) check, you can use this feature to gain a +10 
  bonus to the roll. You can do so after seeing the initial roll 
  but before any of the roll's effects occur. 
       Once you use this feature, you can't use it again until 
  you finish a short or long rest. 
  Jazz Maverick 
  When you reach 10th level, your freewheeling style renders 
  it impossible to hold you down. You are immune to the 
  grappled, paralyzed, and restrained conditions. 
  Voodoo Scat 
  At 14th level, you are blessed with a fragment of Howlin' 
  Jimmy Jefferson's mad genius. You learn the spell 
  destructive wave and can cast it as an action without 
  expending a spell slot. 
       Once you use this feature, you can’t use it again until 
  you finish a short or long rest.
