Entity: Polymath

Source Player Core pg. 98 ^2.0

Your muse is a jack of all trades, flitting between skills and pursuits. Some bards are constantly moved by new muses or draw their inspiration from an idealized being, whether it's based on a real person or purely philosophical. If your muse is a single creature, it might be an eclectic creature like a fey or one who's learned a lot over a long lifespan; if a deity, it might be Desna or Calistria. Art inspired by a polymath muse is restless, with each composition exhibiting new techniques and an ever-evolving style.
As a bard with a polymath muse, you are interested in a wide array of topics but rarely dedicated to any one, and you rarely make up your mind—you want to try everything.
