Master Duelist

You take full advantage of the versatility offered by one-handed weapons. You gain the following benefits while wielding a weapon in one hand and no other weapons.

• You can don or doff a shield as a bonus action.
• When you make a melee attack with a versatile weapon, you can deal the damage the weapon would deal when used with two hands, even if you are only wielding it in one hand.
• When another creature hits you with a melee attack, you can use your reaction to add your proficiency bonus to your AC for that attack, potentially causing the attack to miss you.
