Grappler (Astral Varient)

As a monk of the astral self, you’ve trained your astral arms to grapple and restrain foes. You gain the following benefits:

• Increase your Wisdom score by 1, to a maximum of 20.
• 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, the creature is restrained until the grapple ends.
