Ronin

The ronin dedicate their lives to mastery of the art of swordsmanship. Their ferocity and unwillingness to yield garnish those who follow the path of the ronin a widespread reputation. Though some ronin prefer to work in the shadows, others strive for the spotlight and overcome any challenges that come their way.

Art of the Blade

When you choose this archetype at 3rd level, your training with larger blades allows you to use them more elegantly and precisely. You gain proficiency with the Longsword (if you do not already have it), and the ability to treat a Longsword as a finesse weapon in place of its versatile property. You can draw a finesse weapon as part of an attack action, and when you do so on the first round of combat, you have advantage on your next attack roll.

In addition, you also gain proficiency in calligrapher's supplies.

Rushing Strike

Also at 3rd level, your speed with the sword allows for more deadly blows to an unprepared opponent. When you use your Cunning Action to Dash and you move at least 15 feet in a straight line, you gain advantage on your next melee weapon attack until the start of your next turn. 

In addition, you have developed more unique ways to strike your foes, targeting certain weaknesses. You have a well of points equal to your Wisdom modifier (minimum 1) to spend on the attacks you make against a creature. When you hit a creature with a melee weapon attack, you can choose to spend the necessary points to enhance your attack with one of the following:

1. Crippling Strike (Costs 1): the target’s speed is halved until the end of its next turn.
2. Disorienting Strike (Costs 2): the target has disadvantage on its next attack roll or saving throw.
3. Razor Strike (Costs 3): the target gains vulnerability to the damage of the attack. Also, the next time the target moves, it takes additional damage equal to your Rogue level.

You regain all expended points after you complete a long rest.

Dangerous Reputation

At 9th level, your fame begins to precede you. You are widely known as a swordmaster, and are welcome between many social circles. Your skills have earned the respect of many notable individuals, ranging from noblemen to criminal lords to other skilled swordsmen. You can add your Wisdom modifier to any Charisma-based skill checks. 

Parry Master

Also starting at 9th level, your quick reflexes help to shield you from unanticipated attacks. When you use your Uncanny Dodge ability, you gain a +2 bonus to your AC until the start of your next turn. You cannot apply this bonus if you are unarmed or wearing medium or heavy armor or wielding a shield.

Bladed Demon

At 13th level, you strike down your foes with such ferocity, brutality, and swiftness that your mere presence causes your enemies to cower in fear, while also bolstering the resolve of your allies. Immediately after reducing a creature to 0 hit points, you can attempt to frighten a creature that can see you within 30 feet as a bonus action. The target creature must succeed a Wisdom saving throw (DC=8+wis mod+prof bns) or become frightened of you until the end of your next turn. A creature frightened in this way has disadvantage on all attacks while all attacks against the frightened creature have advantage. 

In addition, if you reduce the frightened creature to 0 hit points, then as a bonus action you can force another creature within 30 feet of you that can see you to make the save against being frightened in this same way. You can continue this streak for a number of creatures equal to your Wisdom modifier. Upon reaching this number, or if a creature succeeds its save, or if you fail to reduce a frightened creature to 0 hit points, then the streak is lost. 

You can use this feature once per short or long rest.

Deadly Counter

Starting at 17th level, when you use your Uncanny Dodge ability as a reaction from being hit by a melee attack, you can make a melee attack against your attacker as part of the same reaction. On a hit, you deal Sneak Attack damage as well.
