Grappling Brawler

You combine your love for brawling and grappling, enhancing your ability to control and dominate opponents in close-quarters combat.  

Tavern Brawler Proficiency:

You gain the benefits of the Tavern Brawler feat, even if you don't have it. This includes the following:

• You are proficient with improvised weapons and unarmed strikes. 
• Your Unarmed Strikes deal 1d4 bludgeoning damage, plus your Strength modifier.  
• When you hit a creature with an Unarmed Strike or an Improvised Weapon attack on your turn, you can use a Bonus Action to attempt to grapple the target. To do so, you must have two free hands. 
• You gain proficiency in the Athletics skill. If you already have proficiency, you instead gain expertise.

Grappler's Advantage:

Your mastery of grappling techniques improves further.  When you successfully grapple a creature, you gain the following benefits:

• The grappled creature's speed becomes 0, and it can't benefit from any bonus to its speed. 
• You have advantage on Attack Rolls against a creature you are grappling.
• While grappling, you can use your Bonus Action to attempt to pin the target. Make a Strength (Athletics) check contested by the target's Strength (Athletics) or Dexterity (Acrobatics) check.  If you succeed, you and the creature are both restrained until the grapple ends.
