Dragonhunter's Grip
When you hit a creature with a weapon attack in melee, if you have a free hand and the target is one or more sizes larger than you, you can expend one superiority die to grab onto it. You add the superiority die to the attack’s damage roll, and you are now holding onto the target; wherever it moves, you move with it. You are dislodged if you are forcibly moved more than 5 feet from the target, or if you no longer have a free hand. The target has disadvantage on any attempt to shove you.
