The Duelling Epee has a +15 piercing talent bonus and a 30–70 damage threshold. It is extremely quick and an excellent choice for those that fancy the piercing talent.
The Duelling Epee is locked inside a level 45 chest inside a locked and guarded storage building on Sword Coast. The building containing the chest is located at the Puerto Isabella. Upon entering the small port town, go past the bar and turn right up the stairs. Once at the top of the stairs turn left and approach Benito. Sneak past this guard and unlock the level 50 door. Once inside, grab all the bags of ammo, a bomb, and then unlock the level 45 chest. Inside the chest is the Duelling Epee.
