Goblinoid Aggression

Your inner ferocity comes forth when someone tries to strike you. You gain the following benefits:

Ability Score Increase. Increase your Dexterity, Constitution, or Charisma score by 1, to a maximum of 20.

Disturbing Visage. When a creature you can see hits you with an attack roll, you can use your Reaction to hiss and snarl, forcing that creature to reroll. Once you use this trait, you can’t use it again until you roll Initiative or until you finish a Short Rest or a Long Rest.
