Braggart

The roguish tradition of the braggart was created by rogues who enjoy the thrill of duels, and can do extraordinary deeds by the power of their self confidence alone. These fencing masters use intimidating bouts and taunts to demoralize their opponents. Often braggarts don't fight for anything other than the enjoyment of the fight itself, treating the swordplay as a sport. Although, those who mistake this style as nothing more than a game, can be surprised by the lethal accuracy of their blades.

Bravado

Starting at 3rd level, you can enter in a special stance called Bravado. You can use an action and make a Charisma (Intimidation) ability check, against a creature you can see and it's 30 feet reach, this check is opposed with a Wisdom (Insight) ability check of the targeted creature. If you surpass the check of your opponent, then you're considered in Bravado. This stance lasts until you or the targeted creature are reduced to 0 Hit Points, you use the Disengage action on your turn, you use a special attack called a finisher, or until the encounter ends, whichever comes first. You are either in a stance of Bravado or you are not.

While you are in Bravado, you gain a +5-foot bonus to your Speeds, and have advantage to your Dexterity (Acrobatics), and Strength (Athletics), ability checks. Also, finishers can be used only while you are considered in Bravado, and  normally cause you to end your stance of Bravado.

Precise Finisher

Also at 3rd level, you gain access to finishers. Finishers are spectacular finishing moves that can be used while you are in Bravado. While you are in Bravado, when you take the Attack action, you can end your Bravado to have advantage with the first weapon attack you make on the turn. You can only use Precise Finisher if you don't have disadvantage on the attack roll.

Morale Boost

At 9th level, when you take damage from an attack, you can use your reaction to gain temporary Hit Points equal to your level plus your Charisma modifier. You can use this feature once, and regain it with a short rest.

Wounding Finisher

A 13h level, while you are in Bravado, when you make a melee weapon attack with a weapon that deals slashing or piercing damage, you can end your Bravado, and if you hit your opponent with this attack, you can make the target takes continuous necrotic damage at the beginning of each of its turn, equals to half the damage you did (rounded up), during a number of rounds equals to your proficiency bonus. Once you use Wounding Finisher, you can't use the Attack action for the rest of your turn.

Lethal Finisher

At 17th level, while you are in Bravado, when you make a melee weapon attack, you can end your Bravado to make your target takes double the damage inflicted if you hit it with this attack, If your attack roll was a critical hit, and your opponent is not reduced to 0 Hit Points, you don't end your Bravado.
