You gain proficiency in the Acrobatics skill and you add double your proficiency bonus to checks you make with it.

Unarmed attacks that you make gain the Finesse property, allowing your unarmed strikes to utilize Dexterity. When using this property, your unarmed strikes deal 1 + your Dexterity modifier Bludgeoning damage.

Additionally, when you use the Shove special action, you may substitute Acrobatics (Dexterity) for the Athletics (Strength) check.
