Marshal Ensnarement

You’ve developed the skills necessary to hold your own in close-quarters Ensnaring. 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 Ensnare a creature by you. To do so, make a grapple check. If you succeed, you and the creature, who now rolls disadvantage +you STR modifier, are both restrained and grappled until the grapple ends.
• You will take 1/2 damage, but due to Ensnarement you can only move 1/2 as far
