Way of the Grasping Hand

Monks of this path largely forsake the fluid movements and graceful strikes of most other forms of martial arts. Rather, they hone their bodies into weapons of pure physical force, able to overpower foes with the strength of their very soul.

Ground and Pound

At 3rd level, you become proficient in Athletics and add double your proficiency bonus when making skill checks with that skill. In addition, you can also use the bonus action unarmed strike from your Martial Arts feature after using your Attack action to shove or grapple a creature.

Soul Binding

Also at 3rd level, you become able to create phantom limbs out of pure ki. When you attempt to grapple a creature, you can spend 1 ki point to cause the grapple to gain the following effects for its duration:

You do not need a free hand to attempt this grapple.

Your reach is considered to be 10 feet for this grapple.

The target must succeed on a Strength(Athletics) or Dexterity(Acrobatics) check contested by your Wisdom(Athletics) check in order to escape.

Tight Grip

At 6th level, your strength surpasses your body's natural limitations. When you use your Soul Binding feature, you count as one size larger than your actual size for the purposes of grappling and moving grappled creatures.

In addition, when you are grappling a creature of your size or smaller (not applying the effective size increase from this feature), the creature is subjected to the restrained condition as well as the grappled condition. This restrained condition ends if the grappled condition ends.

Neck Snap

At 11th level, your technique becomes increasingly lethal. When you roll a 20 on your Athletics check to grapple a creature that has a neck, you can spend 1 ki point as part of that attack to attempt to snap the creature's neck.

The creature must make a Constitution saving throw, taking 10d10 magical bludgeoning damage and becoming paralyzed on a failure (the creature can repeat the saving throw as an action on each of its turns, becoming no longer paralyzed on a success). Creatures that succeed on the saving throw take half as much damage and are not paralyzed.

Attack on Titan

At 17th level, your strength knows no bounds. Grappling attacks you make using your Soul Binding feature can target a creature of Gargantuan size, but you cannot grapple other creatures while grappling a Gargantuan creature.

In addition, your movement is not decreased due to grappling creatures that are Huge or smaller.
