Abilities 40 of Monk
Improved Grapple IV
Unarmed
You trigger an Unarmed ability by attacking the intended target with an Unarmed Attack. If you do not have the Proficiency to use Unarmed Attacks, or that arm is Maimed, you cannot use the ability.
Pin 4
You cannot attack, move, or use abilities other than speaking so long as the user holds you. If the attack was delivered in melee, the user must hold their weapon on you. Otherwise, they must hold a hand up toward you. The effect ends if the user attacks, moves, or uses an ability other than speaking. It also breaks after you are attacked four times. The user may perform these attacks without ending the Pin, and may opt to use one of the attacks to drag you against your will.
