Advanced Dueling

Honor is your Achilles' Heel. I suppose that makes you Achilles. Need not remind you that he was known for much more.

• You gain a additional +2 bonus to damage rolls with all melee weapons while not wielding a shield.
• This is a recharge ability. Roll a 1d6 at each start of your turn and the ability recharges on a 6. As a bonus action, you may designate a target you can see for a duel. Your proficiency score is doubled while the enemy is in range of your melee attack reach. You may add your proficiency score to your melee damage if the attack is against a designated target and you meet the conditions of the Dueling fighting style. When you reduce the target to 0 hit points with a melee attack, this ability immediately recharges.
