You've learned the skills needed to take your grappling to the next level. If you are wielding no weapons and you grapple a creature, you gain the following benefits:

• You may use your Dexterity bonus to grapple instead of your Strength if you choose.
• You add 1d6 bludgeoning damage on attack rolls against a creature you are grappling.
• You can use your bonus action to try to sweep a creature grappled by you. To do so, make another grapple check. If you succeed, the target is knocked prone, and is no longer grappled.
