Bugbear gappling

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.
• When you have successfully grappled a creature, you can use a bonus action to try to push the creature prone. To do so a second hand must be free to make the action. Dropping a weapon or shield is acceptable prior to the push. If you succeed, the creature is both prone and grappled, and must break the grapple prior to addressing the prone condition.
