After playing through the Deadlock Protocol I promptly fell in love with the [Xoris] with its beautiful graphics and sound design. Then, once I found out it's not even a bad weapon, I decided to try making a build of my own, and here it is!
[Fury] can be replaced with [Pressure Point] to have a higher starting damage, but it'll leave you with a slightly lower final sustained DPS once you've hit 12 stacks.
The point of this build is to max out your combo stacks with the weapon's infinite combo duration, so try not to use the heavy attack too much. That said, throwing the weapon without detonating it does not consume combo stacks so go nuts!
