Pit Brawler (Khemti)

You were trained to fight as a slave in the brawl pits of your race's demonic masters.   Forced to improvise with whatever items happen to be at hand, you gain the following benefits:

• Increase your Strength or Constitution score by 1, to a maximum of 20.
• You are proficient with improvised weapons.
• Your unarmed strike uses a d4 for damage.
• When you hit a creature with an unarmed strike or an improvised weapon on your turn, you can use a bonus action to attempt to grapple the target.
