While others were side questing, you studied the blade. When you take this feat, you learn one of the actions below. You must be wielding a dagger, greatsword, longsword, scimitar, or shortsword to perform any of these actions. You can use a learned action a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.   You can select this feat multiple times. Each time you do so, you learn an additional action.
