Disciplined Swordsman

Ok, i really just want an anime swordsman who can do a bunch of attacks in an intstant to look like a badass when it goes well, or a dumbass when i fail.

Identify/Exploit

When you choose this archetype at 3rd level, you learn how to Identify and Exploit the weaknesses of a creature that missed you. As a reaction when missed, you can Identify a weakness in your enemy.

During your turn, if you hit with a melee attack against a creature, you can deal half damage (rounded down) to Exploit the enemys weakness, doing a different effect based on the weakness Exploited.

Dueling Form

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

Focus Target

You choose a creature you can see within range and focus on it as your quarry. For as long as you only attack this target you deal an extra 1d6 damage whenever you hit it with a weapon attack, and you have advantage on any Wisdom (Perception) or Wisdom (Survival) check you make to find it.  If the target drops to 0 hit points you can use a bonus action on a subsequent turn of yours to mark a new creature. Whenever you break focus you are stunned for 1 round.

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.

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.
