You may not be intimidating with your words, but an ugly look might be all it takes. You ignore your normal modifier and add 1 to intimidation checks you make unless you have a higher modifier, then you add one to your modifier. You can make an intimidation check with advantage a number of times per short rest equal to 1+ your Charisma modifier (minimum of 1). This only effects creatures that can see your face and are not immune to the afraid condition.
