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 to learn from that same list. Using this feat, you can cast the spell once at its lowest level, and you must finish a long rest before you can cast it in this way 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.
