Chi-Blocking

General Feat (Prerequisite: Dexterity 15+)

You gain the following benefits.

Ability Score Increase. Increase your Dexterity or Wisdom score by 1, to a maximum of 20.

Chi hit and block. When you hit a creature with an Unarmed Strike as part of the Attack action on your turn, it temporarily paralyzes the creature's body part that you hit, and if it's a magical being, it temporarily stops magic from flowing through that body part.

Attack Advantage. You have Advantage on attack rolls against a creature you have paralyzed.

Used twice. If a creature with moderate intelligence has either seen you perform or has had chi-blocking performed on them by the person, you don't gain any advantage against them, and if they know it themselves, you gain disadvantage on your roll.
