Magic Initiate

Choose a class: Bard, Cleric, Druid, Sorcerer, Warlock, or Wizard. You learn two cantrips of your choice from that class’s spell list.

In addition, choose one 1st-level spell from that same list. You learn that spell and can cast it at its lowest level. Once you cast it, you must finish a long rest before you can cast it again.

Your spellcasting ability for these spells depends on the class you chose: Charisma for bard, sorcerer, or warlock; Wisdom for cleric or druid; or Intelligence for wizard.
