Requires Choke-Hold Feat

When you are grappled, you can use your action to reverse
the grapple. Make a grapple check against the creature. If
you succeed, you are no longer considered grappled and the
creature that was grappling you becomes grappled by you if it is
your size or smaller.
Additionally, you have advantage on melee attacks you make
against a creature you are grappling.
