Ronin

The way of the Ronin has been practiced for generations, and is based upon anticipation of your enemy's next move. Those who follow the way of the Ronin value patience, and using your enemy's lack thereof against them.

The path of the Ronin centers around quick attacks, and waiting for your enemy to make their move against you. Due to this, a Ronin's mind is trained to search for their target's weaknesses, and exploit them in battle. Through patience comes strength, strength of the mind and the blade.

Way of the Blade

When you choose this archetype at 3rd level, you gain the ability to use either your Strength or Dexterity modifiers for attack and damage rolls, your choice.

This feature can be used with any weapon that doesn't have the heavy property.

(Author's Note: Make a custom action in your actions page to remedy the choice)

Anticipation

Starting at 3rd level, you learn to wait patiently in battle. You can dodge as a bonus action, which ends your turn. While dodging, you can use your reaction to attack an enemy attacking you. You have advantage on the attack roll.

You can use this feature a number of times equal to twice your proficiency bonus. You regain all expended uses on a short or long rest.

Warrior's Mind

Starting at 7th level, your warrior mind has sharpened to pick up on the weaknesses of your enemy. You gain proficiency in the Insight skill. If you are already proficient, your proficiency bonus is doubled with that skill.

Additionally, you can use your bonus action to make an Insight check to determine how hurt your target is (at DM's discretion), contested by the opponent's Deception check.

Focused Mind

Starting at 10th level, you gain proficiency in Wisdom saving throws.

Improved Way of the Blade

Starting at 15th level, your keen mind for battle intensifies. When you use your reaction strike with Anticipation, you score a critical hit on a roll of 19-20.

Anticipation: Lethal Flurry

Starting at 18th level, whenever you use your Anticipation: Reactive Strike, you can make two attacks against an enemy attacking you. Additionally, after you've taken your Anticipation bonus action, you can use your reaction to make an attack against any hostile creature that enters your melee range.
