The Flechette Orb provides Puncture Damage as the main output, with the Eclipse and Overdriver adding damage and frequent f-button presses to trigger Speed Holster and Vigorous Swap for very high Puncture Damage. This builds needs to be perfected, but can be used in general survival/interception missions.
If you don't have enough energy, you need to combine it with the [Energizing Shot] and the Tesla Nervos skill.
If you have a teammate to help you out, such as Ivara's Empowered Quiver, you can do more damage.
