Brawler

Tavern Brawler. Increase Strength score by 1. Proficient with improvised weapons. Unarmed strike does 1d4 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. 

Attacker. The brawler gains a +2 bonus to attack rolls. Can use a bonus action to dash, disengage, or hide.

Fist.1d4 + 2 bludgeoning damage

Vicious Mockery. You unleash a string of insults laced with subtle enchantments at a creature you can see within range. If the target can hear you (though it need not understand you), it must succeed on a Wisdom saving throw or take 1d4 psychic damage and have disadvantage on the next attack roll it makes before the end of its next turn.

Acidic Brew. As a bonus action, the brawler can make a sleight-of-hand check against their opponent's passive perception to pour a small vial of acid into a nearby drink. The drink deals 2d6 acid damage.
