Dueling Master

You've learned to be quick and precise with your weapons. You gain the following benefits:

• On your turn, when you miss with an attack with a melee weapon against a creature, you can make one melee weapon attack against the same creature as a bonus action.
• If you make an attack with a one-handed melee weapon and have advantage on an attack roll against the target, you can forgo the advantage for that roll to deal additional damage equal to a roll of the weapon's damage die if the attack hits.
