Dilettante

With a few minutes of preparation, a bit of improvisation, and some talent, you can appear proficient in just about anything. When you finish a long rest, you can spend 10 minutes practicing with a simple or martial weapon, skill, or tool, or in the use of a cantrip from the wizard spell list. You gain proficiency with that weapon, skill, or tool, or you learn that cantrip until you finish a long rest. Intelligence, Wisdom, or Charisma is your spellcasting ability for this cantrip when you cast it using this feat (choose when you select the cantrip).
