You gain the following benefits:

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

Precision Off-Hand. When you take the Attack action on your turn and attack with a weapon that has both the Light and Finesse properties, you can add your proficiency modifier to the damage of an attack made as a Bonus Action with your other weapon (as part of Two-Weapon Fighting).
