Grappler (Revised)

You’ve developed the skills necessary to hold your own in close-quarters grappling. You gain the following benefits:

• You have advantage on attack rolls against a creature you are grappling.
• You can use your action to try to pin a creature grappled by you. To do so, make another grapple check. If you succeed, you and the creature are both restrained until the grapple ends.
• When you hit a creature with an unarmed strike or natural weapon, you can use a bonus action to attempt to grapple that creature.
• When a creature you grapple is restrained or knocked down, you can use a bonus action to use them as cover; half-cover if they are up to your size or three-quarters-cover if they are of a larger size than you.
