Grappler Improved

You’ve developed the skills necessary to hold your own in close-quarters grappling. You gain the following benefits:

• You have advantage on attack rolls against a creature you are grappling.

In addition, you gain the following maneuvers:

• Head Smash: You attempt to smash your head against against the head of your target you are already grappling. Make a new contested grapple check, on a success the target must make a Con saving throw or be stunned for one round.
• Charging Tackle: You attempt to tackle and pin your opponent to the ground. After moving at least 10 feet towards your target, make contested grappling checks. On a success, both characters fall prone, with the target being restrained for one round, so long as you remain your position on top of them.
• Wrist Grab: You attempt to take away some of your targets maneuverability and danger by controlling their forelimbs. Make a new grapple check, on a successful check the target is forced to drop their weapon in that hand and cannot use that forelimb until they successfully escape.
