Chain Fighter

You’ve developed the skills necessary to hold your own while using Chain weapons. You gain the following benefits:

• You have advantage on attack rolls against a creature that has no weapons.
• You can use your action to try to pin a creature grappled by you. To do so, make a grapple check. If you succeed, you and the creature are both restrained until the grapple ends. The grappled creature takes 1d4 damage every turn it remains grappled.
