You learn two spells of your choice. These spells can come from the Cleric, Druid, or Wizard spell list or any combination thereof (see a class’s section for its spell list). A spell you choose must be a cantrip or a spell for which you have spell slots, as shown in the Bard Features table.
You always have the chosen spells prepared, and whenever you gain a Bard level, you can replace one of the spells with another spell that meets these requirements.
