Skillful Melee

You’ve developed the skills necessary to hold your own in close-quarters combat, using intimidation tactics to better your adversary. You gain the following benefits:

• You gain disadvantage on attack rolls against creatures further than 10ft.
• You can use your bonus action to try to disarm a creature that is currently grappled by you. To do so, make another grapple check on top of the already grappled creature. If you succeed, the creature is disarmed and they have disadvantage on picking their weapon back up.
• Before you attack a creature within 5ft of you, you may use up all of your movement doing a haka or a war-dance up to 5 times per long rest, if you do so, roll an Intimidation check and divide it by 2 (example: If you roll a 3, its going to be 1.5, so just round up to 2). Whatever the Intimidation check ends up being by the end, add that your attack roll. (example: If you rolled a 10 to hit, and your intimidation was a 2, your roll to hit is now a 12.)
