Leg-Sweeper

You like to keep your enemies at your feet. You gain the following benefits:

• Creatures within your reach provoke opportunity attacks from you if they try to stand up from prone.
• When you make a shove attack to knock a creature prone, you have advantage on the Strength (Athletics) check.
• You can use your action to try to pin a creature that is both prone and grappled by you. To do so, make another grapple check. If you succeed, you and the creature are both restrained until the grapple ends.
