Two-Weapon Fighting
Two-Weapon Fighting lets the Fighter add their ability score modifier to offhand attack damage.
How it works
This is a level-one Fighter Fighting Style choice. Its effect is tied to making an offhand attack: the Fighter can add their Ability Score Modifier to that attack's damage. The supplied passage gives no rest-based use limit.
