After using cantrips for a while, you have learned how to cast multiple cantrips in short periods of time. You have four charges and regain one charge for every short rest and all four from a long rest. Expending a charge allows you to cast two cantrips in a single turn. This feat also extends your knowledge on cantrips. You can now learn a cantrip from a spell scroll in 20 minutes. You also learn one more cantrip of your choice from any class.
