Armor Lock

You swiftly adjust your enemy’s armor so that they cannot move.

Make a Sleight of Hand check against the AC of a creature within reach that is wearing armor, paralyzing it on a success. At the beginning of each of its turns, a creature paralyzed by this maneuver can make a Strength saving throw , ending the effect on itself on a success (unlike normal, the paralyzed creature doesn’t automatically fail this save.)

A creature wearing heavy armor has disadvantage on its saving throw.
