Swarmer
Swarmers are boxers who apply constant pressure on their opponents by delivering a barrage of punches, relying on quick strikes and fast footwork to rampage towards the enemy and leaving it locked behind the tempest of blows.
Rhythm Abilities
Punch Swarm. You can make one additional unarmed strike or glove weapon attack, plus an additional one each time you hit, up to 5 attacks. You don't add your ability modifier to the damage of these attacks.
Pushing Flurry. The target must succeed on a Wisdom saving throw, on a failure, the target is pushed up tp 10 feet away from you and you move up to 10 feet toward it (without provoking opportunity attacks). If the target was pushed, it has disadvantage on the next Wisdom saving throw or Wisdom ability check it makes until the end of its next turn.
Slip and Counter
At 9th level, you can throw a punch as a reaction against a creature that misses a melee attack against you, within 5 feet.
Correcting Target
At 13th level, once per round when you take the Attack action and miss a target with a punch, you can reroll the attack with advantage.
Overwhelm
At 17th level, at the start of your first turn of combat, if you aren't surprised, you can take the attack action to make six unarmed strikes or glove weapon attacks. Once you use this feature, you must finish a short or a long rest before you are able to use it again.
