The mastered hand tradition teaches monks how to use their palms as conduits for the ki flowing trough their bodies. Instead of focusing on aggressive strikes and in the power of their bodies, a gentle touch of their hands can disrupt the ki inside their enemies, causing great harm.

Channeling the ki to the palms is also useful to defensive methods of fighting, using the hands as a barrier for the rest of the body, shielding the monk from strikes.

Pressure Strikes

Disarm

At 6th level, you can use your reaction to parry or catch a weapon when you are hit by a melee weapon attack. When you do so, the damage you take from the attack is reduced by 1d10 + your Dexterity modifier + your monk level. If you reduce the damage to 0, you knock the weapon from the attacker's grasp.

You can use your action to disarm an opponent. Make a Dexterity or Strength check contested by the target's Strength check. If the target lose the context, the weapon is knocked out of his hand. If he win, the target have disadvantage on its next attack.

The vibrations are harmless unless you use your action to end them. To do so, you and the target must be on the same plane of existence. When you use this action, the creature must make a Constitution saving throw. If it fails, it is reduced to 0 hit points. If it succeeds, it takes 10d10 necrotic damage.

You can have only one creature under the effect of this feature at a time. You can choose to end the vibrations harmlessly without using an action.
