Star Wars: A Flicker of Hope
The dueling lightsaber isn’t so much a variant lightsaber as it is a hilt style engineered specifically to enhance lightsaber duels. Count Dooku and his apprentices, Komari Vosa and Asajj Ventress, wield dueling lightsabers that feature a curved hilt designed to maximize the potential of a one-handed finesse-based fighting style.
When you wield a dueling lightsaber one-handed, you gain a +1 equipment bonus on attack rolls whenever you make an attack of opportunity with the weapon.
A dueling lightsaber requires an energy cell to operate.
