If he gets someone with that whip, there's a good chance things are going to get up close and personal. Practice art of another one of Braun's level 2 abilities!

Whip Enthusiast:

At 2nd level, when you take the Attack action with a whip, you may use your bonus action to attempt to grapple the creature. All standard grappling conditions apply to make this attempt. On a successful grapple, the target is restrained and you may not attack with the whip again until the grapple ends.
