You’ve developed the skills necessary to hold your own in close-quarters grappling using your acrobatic prowess. 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.
• You must use your acrobatics score instead of your athletics score when attempting a grapple. The creature you attempt to grapple may choose either score to contest your acrobatics.
