I know [Sweeping Serration] doesn't make slash procs more powerful but i put it there to tip the damage distribution in favour of slash so it has more or less the same chance as viral to proc. If you subsume [Xata]'s whisper you can add void damage. Why would you do this? Because you'd also have a chance to proc void's status, bullet attractor, which doesn't only attract bullets but allows projectiles with punch through to penetrate enemies multiple times until the punch through runs out. And [Exergis] has infinite punch through on bodies. Hence, stonks.
