Robot Swashbuckler

You focus your training on the art of the blade, relying on speed, elegance, and charm in equal parts. While some warriors are brutes clad in heavy armor, your method of fighting looks almost like a performance. Duelists and pirates typically belong to this archetype.

Fancy Footwork

When you choose this archetype at 3rd level, you learn how to land a strike and then slip away without reprisal. During your turn, if you make a melee attack against a creature, that creature can't make opportunity attacks against you for the rest of your turn.

You only need to attack the target, not hit them, so if you miss and don’t want to stay in melee range you’re free to retreat unimpeded. Using two light-weapons for two-weapon fighting allows you to move past and attack two enemies if you feel the need. The choice between using Cunning Action to Disengage and relying on Fancy Footwork will depend both on what you’re wielding and on how many enemies you need to evade.

 

Rakish Audacity

Starting at 3rd level, your confidence propels you into battle. You can give yourself a bonus to your initiative rolls equal to your Charisma modifier.

You also gain an additional way to use your Sneak Attack; you don't need advantage on the attack roll to use your Sneak Attack against a creature if you are within 5 feet of it, no other creatures are within 5 feet of you, and you don't have disadvantage on the attack roll. All the other rules for Sneak Attack still apply to you.

Any Rogue can Sneak Attack if an ally is within 5 feet of the target. Rakish Audacity allows you to Sneak Attack if no one except the target is adjacent to you, which means that as long as you’re not getting mobbed you can reliably Sneak Attack whenever you hit. 

Panache

At 9th level, your charm becomes extraordinarily beguiling. As an action, you can make a Charisma (Persuasion) check contested by a creature's Wisdom (Insight) check. The creature must be able to hear you, and the two of you must share a language.

If you succeed on the check and the creature is hostile to you, it has disadvantage on attack rolls against targets other than you and can't make opportunity attacks against targets other than you. This effect lasts for 1 minute, until one of your companions attacks the target or affects it with a spell, or until you and the target are more than 60 feet apart.

If you succeed on the check and the creature isn't hostile to you, it is charmed by you for 1 minute. While charmed, it regards you as a friendly acquaintance. This effect ends immediately if you or your companions do anything harmful to it.

 

Elegant Maneuver

Starting at 13th level, you can use a bonus action on your turn to gain advantage on the next Dexterity (Acrobatics) or Strength (Athletics) check you make during the same turn.

This uses your Bonus Action just to grant you Advantage, so you still need to use your Action to use the skill, leaving you no opportunity to attack. 

 

Master Duelist

Beginning at 17th level, your mastery of the blade lets you turn failure into success in combat. If you miss with an attack roll, you can roll it again with advantage. Once you do so, you can't use this feature again until you finish a short or long rest.
