Ratio Technique (improved)

The user of this technique can mark their target's body with lines divided into tenths. If the user is able to strike one of these lines on exactly the seven-to-three ratio point, they deliver a critical hit to the subject. This allows them to deal significant damage on tougher adversaries and cleave weak opponent's in two in a single hit.

The lines don't have to measure up to the target's full length or wingspan. Their head, torso, biceps, and forearms are all among applicable limbs for division. This technique can be used on inanimate objects in addition to living beings

Seven to Three Ratio Technique

Beginning when you choose this archetype at 3rd level, as a bonus action you can mark a creature you see, and if you hit it with a attack they must make a CON saving throw DC strength +your proficiency and on a failed save you can add 2d6 damage along with advantage against that target until the beginning of your next turn.

Deadly Ratio

Starting at 7th level, once a creature is marked and hit they suffer heavy damage and there movement speed is halved and until the end of there next turn they get one less attack than they normally do and they cant use any special traits.

Resilient Vigor

Starting at 10th level, once you've marked a target and hit them you gain 20 temporary hp until the end of your next turn. you can only use this once per short rest

Superior Critical

Starting at 15th level, your weapon attacks score a critical hit on a roll of 18–20.

Master of the Ratio Technique

At 18th level,  once you have successfully marked and hit a creature you can forgo the advantage and 1 of your attacks to deal 8d6 (+your strength modifier) necrotic damage to them and if you do they lose a limb and the get two levels of exhaustion. You cant use this until you've completed a long rest.
